Network Security Assessment Checklist for Small Businesses in 2026

Small businesses account for 43 percent of all cyberattack targets, yet fewer than 14 percent have adequate defenses in place, according to the 2025 Verizon Data Breach Investigations Report. The disconnect is staggering: the organizations least equipped to survive a breach are the ones attackers pursue most aggressively. A single ransomware event can cost a small business between $120,000 and $1.24 million when accounting for downtime, data recovery, regulatory fines, and reputational damage. For many, that is an extinction-level event.

A network security assessment is the structured process of identifying vulnerabilities, misconfigurations, and gaps across every layer of your IT infrastructure before an attacker exploits them. It is not a one-time project. It is a recurring discipline that separates businesses that survive from those that become statistics. At Petronella Technology Group, we have conducted thousands of these assessments over 24 years for organizations across healthcare, defense contracting, legal, financial services, and manufacturing. The checklist below distills that experience into a practical framework any small business can use to evaluate and strengthen its network security posture.

Craig Petronella, founder of Petronella Technology Group, NC Licensed Digital Forensics Examiner, and author of 15 books including How Hackers Can Crush Your Business, developed this checklist based on real-world findings from assessments across the Research Triangle and nationwide. Every item on this list has been validated against the most common attack vectors we see exploited in the field.

Why Small Businesses Cannot Afford to Skip Network Assessments

The threat landscape in 2026 has shifted dramatically. Artificial intelligence has lowered the barrier to entry for attackers, enabling automated reconnaissance, polymorphic malware, and highly convincing phishing campaigns that can be generated at scale. Nation-state attack tools that were once reserved for targeting governments and Fortune 500 companies now appear routinely in attacks against businesses with 50 employees or fewer. The assumption that small businesses are too small to be targeted has never been more dangerous.

Beyond the direct threat of attack, network security assessments serve critical business functions. Cyber insurance carriers now require documented assessments as a condition of coverage, and claims are routinely denied when organizations cannot demonstrate they conducted regular security reviews. Compliance frameworks including HIPAA, CMMC, PCI DSS, SOC 2, and ISO 27001 all mandate periodic risk assessments. And prospective clients, especially enterprise buyers evaluating small business vendors, increasingly require evidence of security assessments during procurement reviews.

Petronella Technology Group has maintained a zero-breach record across all managed clients since 2002. That track record is built on proactive assessment, not reactive response. The checklist below reflects the same methodology we use with our 2,500+ clients.

The Complete Network Security Assessment Checklist for 2026

This checklist covers 15 critical assessment areas. For each item, we explain what to evaluate, why it matters, and what a passing result looks like. Use this as a self-assessment guide, or bring it to your next conversation with a virtual CISO or security provider.

1. Perimeter Security and Firewall Configuration Review

Your network perimeter is the first line of defense, and it is often the most neglected. Firewalls accumulate rules over years of changes, employee departures, vendor requirements, and emergency exceptions. The result is typically a rule base with dozens of overly permissive entries that no one fully understands and no one wants to touch for fear of breaking something.

Start by exporting your firewall rule base and reviewing every rule. Identify rules that allow traffic from "any" source or to "any" destination. Check for rules permitting inbound access on high-risk ports such as RDP (3389), SSH (22), SMB (445), and Telnet (23). Verify that default administrator credentials have been changed on all network devices including firewalls, switches, routers, and access points. Document every open port and the business justification for each one.

A proper perimeter review should also include external vulnerability scanning. PTG's Managed XDR Suite performs continuous external attack surface monitoring, identifying exposed services and misconfigurations in real time rather than waiting for the next annual assessment. The difference between continuous monitoring and annual scanning is the difference between catching a misconfiguration in hours versus leaving it exposed for months.

Passing criteria: No unnecessary open ports, no default credentials on any network device, all firewall rules documented with business justification and expiration dates, external scan showing no critical or high-severity findings.

2. Internal Network Segmentation Analysis

A flat network is an attacker's most valuable asset after initial access. Once inside a network with no segmentation, lateral movement is trivial. The attacker can reach file servers, databases, payment systems, email servers, and backup infrastructure from any compromised endpoint. Proper segmentation limits the blast radius of any breach and is explicitly required by HIPAA, PCI DSS, CMMC, and SOC 2.

Evaluate your VLAN architecture. Critical systems such as servers, databases, payment processing, and medical devices should be on isolated network segments with controlled access between them. Guest wireless should be completely isolated from production networks. IoT devices, which are notoriously insecure, should be on their own segment with strictly limited outbound access. Printers and multifunction devices, which are frequently overlooked, should also be segmented because they often run outdated firmware with known vulnerabilities.

Test your segmentation by attempting to access resources across segments without authorization. Many organizations implement VLANs but fail to configure inter-VLAN routing restrictions, rendering the segmentation cosmetic rather than functional. PTG's ComplianceArmor platform maps your network segmentation against specific compliance control requirements, identifying gaps between your current architecture and what regulators expect.

Passing criteria: Minimum four network segments (production servers, user workstations, guest/IoT, management), inter-VLAN access controlled by firewall rules, no unauthorized cross-segment access confirmed by testing.

3. Wireless Security Assessment

Wireless networks expand your attack surface beyond the physical walls of your office. An attacker sitting in the parking lot with a laptop and a directional antenna can attempt to compromise your wireless infrastructure without ever entering the building. Wireless security failures are among the most common findings in our assessments, and they are among the easiest to exploit.

Verify that all wireless networks use WPA3 or, at minimum, WPA2-Enterprise with RADIUS authentication. WPA2-Personal with a shared pre-shared key is insufficient for business environments because every employee and former employee who ever received the password retains access until the key is changed. Check for rogue access points, which are unauthorized wireless devices connected to your network, often installed by employees seeking better coverage. Conduct a site survey to identify signal leakage outside your premises and adjust power levels accordingly.

Review guest wireless configuration. Guest networks should provide internet access only, with no ability to reach internal resources. Verify that client isolation is enabled so that devices on the guest network cannot communicate with each other. Check that a captive portal or acceptable use agreement is in place for guest access.

Passing criteria: WPA3 or WPA2-Enterprise on all production networks, no rogue access points detected, guest network fully isolated with client isolation enabled, wireless signal contained to premises.

4. Access Control and Identity Management Verification

Access control failures are the root cause of the majority of breaches. The principle of least privilege, granting users only the minimum access required to perform their job functions, is universally recommended and almost universally violated. Excessive permissions accumulate as employees change roles, take on temporary projects, and receive access grants that are never revoked.

Audit your Active Directory or identity provider. Identify accounts with domain administrator privileges and verify each one is assigned to a named individual with a documented business need. Check for service accounts with excessive privileges, especially those using shared or default passwords. Review group memberships for privilege creep, where users retain access from previous roles. Verify that all terminated employee accounts are disabled within 24 hours of departure.

Multi-factor authentication is non-negotiable in 2026. Verify that MFA is enforced on all remote access including VPN, email, and cloud applications. Check that MFA is also required for all administrative access to servers, network devices, and cloud management consoles. SMS-based MFA should be replaced with authenticator apps, hardware tokens, or passkeys, as SIM-swapping attacks have made SMS verification unreliable.

PTG's vCISO services help organizations design and implement zero-trust access architectures that enforce least privilege systematically rather than relying on manual access reviews that inevitably fall behind.

Passing criteria: All privileged accounts documented and justified, MFA enforced on all remote and administrative access, no shared or default passwords on service accounts, terminated user accounts disabled within 24 hours.

5. Endpoint Security Posture Assessment

Every endpoint, whether a workstation, laptop, mobile device, or server, is a potential entry point for attackers. Endpoint security has evolved well beyond traditional antivirus, and organizations still relying solely on signature-based antivirus are effectively unprotected against modern threats.

Verify that every endpoint runs an Endpoint Detection and Response (EDR) solution capable of behavioral analysis, not just signature matching. Check that EDR agents are installed, running, and reporting to a central management console on 100 percent of endpoints. Identify any unmanaged devices on the network using network scanning tools. Verify that endpoint disk encryption (BitLocker on Windows, FileVault on Mac) is enabled on all devices, especially laptops that leave the office.

Review mobile device management policies. Personal devices accessing company email or data should be enrolled in an MDM solution that can enforce screen locks, encryption, and remote wipe capability. Check that USB mass storage is disabled or controlled by policy on workstations handling sensitive data.

Passing criteria: EDR deployed on 100 percent of endpoints, full disk encryption enabled on all devices, MDM enforced on all mobile devices accessing company resources, no unmanaged devices on the network.

6. Email Security and Phishing Defenses

Email remains the primary attack vector for small businesses. Over 90 percent of successful cyberattacks begin with a phishing email, and AI-generated phishing campaigns in 2026 are virtually indistinguishable from legitimate communications. Your email security posture determines whether these attacks succeed or fail.

Validate your email authentication records. SPF (Sender Policy Framework) must be configured to specify which servers are authorized to send email for your domain. DKIM (DomainKeys Identified Mail) must be enabled to cryptographically sign outbound messages. DMARC (Domain-based Message Authentication, Reporting, and Conformance) must be set to a policy of quarantine or reject, not "none," which provides monitoring but no protection. Check that DMARC reports are being collected and reviewed.

Evaluate your email security gateway or filtering solution. It should provide URL rewriting and time-of-click analysis, attachment sandboxing, impersonation protection for executives, and integration with your EDR platform. Review phishing simulation results from the past 12 months. If you are not conducting regular phishing simulations, that is itself a critical finding.

DNS filtering should block access to known malicious domains and newly registered domains, which are disproportionately used in phishing and malware distribution. Verify that DNS-over-HTTPS is not bypassing your DNS filtering controls.

Passing criteria: SPF, DKIM, and DMARC properly configured with DMARC at quarantine or reject, email security gateway with URL and attachment analysis, phishing simulations conducted quarterly with click rates below 5 percent.

7. Patch Management and Vulnerability Remediation

Unpatched vulnerabilities are the second most exploited attack vector after phishing. The window between vulnerability disclosure and active exploitation has shrunk to days or even hours for critical vulnerabilities. Organizations that patch on a monthly cycle are leaving themselves exposed for weeks after each new disclosure.

Conduct a comprehensive vulnerability assessment across all systems. This includes not just servers and workstations but also network devices (firewalls, switches, routers), IoT devices, printers, and any internet-facing applications. Prioritize findings by exploitability and business impact, not just CVSS score. A medium-severity vulnerability on an internet-facing system may pose more risk than a critical vulnerability on an isolated internal system.

Review your patch management process. Critical and high-severity patches should be deployed within 72 hours of release for internet-facing systems and within 14 days for internal systems. Verify that all operating systems, applications, and firmware are within their vendor support lifecycle. End-of-life software that no longer receives security updates, such as Windows Server 2012 or legacy versions of Microsoft Office, must be upgraded or isolated.

PTG's managed IT services include automated patch management with testing and staged deployment, ensuring critical patches are applied rapidly without disrupting business operations.

Passing criteria: No critical unpatched vulnerabilities on internet-facing systems, all software within supported lifecycle, patch deployment within defined SLAs, vulnerability scan conducted within the past 30 days.

8. Backup and Disaster Recovery Validation

Backups are your last line of defense against ransomware, hardware failure, and human error. Yet we routinely discover during assessments that organizations have not tested their backup recovery in months or years. A backup that has never been tested is not a backup. It is a hope.

Verify that backups follow the 3-2-1-1 rule: three copies of data, on two different media types, with one copy offsite and one copy immutable (cannot be modified or deleted by ransomware). Check that backup encryption is enabled both in transit and at rest. Verify that backup credentials are separate from production domain credentials, so that an attacker who compromises Active Directory cannot also delete your backups.

Test recovery procedures. Perform a full system restore of at least one critical server to verify that the backup is complete, the recovery process works, and your team knows how to execute it under pressure. Document the Recovery Time Objective (RTO) and Recovery Point Objective (RPO) for each critical system and verify that your backup schedule meets these objectives.

Review your disaster recovery plan. Does it account for scenarios beyond ransomware, including natural disasters, hardware failure, cloud provider outages, and insider threats? When was the plan last updated? When was it last tested? Who is responsible for executing it?

Passing criteria: 3-2-1-1 backup strategy in place, immutable backups configured, full recovery test completed within the past 90 days, documented RTO/RPO for all critical systems, disaster recovery plan updated within the past 12 months.

9. Logging, Monitoring, and Incident Detection

Without adequate logging and monitoring, breaches persist undetected for an average of 194 days according to IBM's 2025 Cost of a Data Breach Report. Nearly seven months of unauthorized access before anyone notices. For a small business, that is seven months of data exfiltration, seven months of credential harvesting, and seven months of attacker entrenchment that will make remediation exponentially more difficult and expensive.

Verify that critical systems generate security audit logs. This includes authentication events (successful and failed), privilege escalation, file access on sensitive shares, firewall rule changes, email forwarding rule creation, and administrative actions on all systems. Logs must be forwarded to a centralized log management system or SIEM (Security Information and Event Management) platform where they are protected from tampering.

Check log retention policies. Most compliance frameworks require a minimum of 12 months of log retention, with some requiring longer. Verify that log storage capacity is adequate and that logs are not being silently dropped due to storage constraints. Review alerting rules to ensure that high-priority events, such as multiple failed authentication attempts, new administrator accounts, or data exfiltration indicators, trigger immediate notifications.

PTG's 24/7 SOC (Security Operations Center) through our Managed XDR Suite provides continuous monitoring with human analysts reviewing alerts around the clock. This is a level of detection capability that most small businesses cannot build internally but can access through a managed service.

Passing criteria: Centralized log collection from all critical systems, minimum 12-month retention, automated alerting on high-priority events, logs protected from tampering with integrity verification.

10. Cloud Security Configuration Review

The migration to cloud services has introduced an entirely new category of security risk: misconfiguration. Cloud breaches are overwhelmingly caused not by sophisticated attacks but by simple misconfigurations, such as publicly accessible storage buckets, overly permissive IAM policies, and unencrypted databases. The shared responsibility model means your cloud provider secures the infrastructure, but you are responsible for securing your configuration.

Review IAM (Identity and Access Management) policies across all cloud platforms. Identify any policies granting wildcard permissions. Check for access keys that have not been rotated within 90 days. Verify that root or global administrator accounts are secured with hardware MFA tokens and are not used for routine operations.

Audit storage configurations. Verify that all storage buckets, blobs, and file shares are private by default. Check that server-side encryption is enabled. Review sharing settings to ensure no sensitive data is publicly accessible. Scan for exposed API keys, database connection strings, and credentials in code repositories.

Evaluate network security groups and firewall rules in cloud environments. Apply the same rigor you would to on-premises firewall rules: no unnecessary inbound access, no overly permissive outbound rules, and all rules documented with business justification.

Passing criteria: No wildcard IAM permissions, all storage private by default, encryption enabled on all data at rest and in transit, no exposed credentials, cloud security posture management (CSPM) tool deployed.

11. Compliance Mapping and Gap Analysis

For small businesses operating in regulated industries, network security assessments must map directly to applicable compliance requirements. A technically thorough assessment that does not address compliance obligations is incomplete, and a compliance-focused assessment that does not address real-world threats is theater.

Identify every regulatory framework that applies to your organization. Common frameworks for small businesses include HIPAA (healthcare data), CMMC (defense contracting), PCI DSS (payment card data), SOC 2 (service providers), and state privacy laws. Map each assessment finding to the specific compliance controls it satisfies or violates. Document remediation actions with timelines and responsible parties.

PTG's ComplianceArmor platform automates compliance mapping across multiple frameworks simultaneously. Rather than conducting separate assessments for each framework, ComplianceArmor identifies overlapping controls and generates unified documentation that satisfies multiple auditors from a single assessment effort. This reduces assessment costs and eliminates the inconsistencies that arise when different teams assess the same environment against different standards.

Passing criteria: All applicable compliance frameworks identified, assessment findings mapped to specific controls, gap analysis documented with remediation timelines, evidence package organized for audit readiness.

12. Incident Response Plan Testing

Having an incident response plan is not enough. The plan must be tested, and the people responsible for executing it must practice under simulated conditions. An untested incident response plan fails at the worst possible moment: when a real incident creates the pressure, confusion, and urgency that expose every gap in preparation.

Verify that a documented incident response plan exists and has been updated within the past 12 months. The plan should define roles and responsibilities, communication procedures (internal and external), containment strategies for common incident types, evidence preservation procedures, and regulatory notification requirements. Check that contact information for key responders, legal counsel, cyber insurance carriers, and law enforcement is current.

Conduct a tabletop exercise. Walk through a realistic scenario, such as a ransomware attack discovered on a Friday evening, and evaluate how your team responds. Identify decision points where uncertainty or delay would worsen the outcome. Document lessons learned and update the plan accordingly.

PTG provides penetration testing services that include incident response validation, testing not just whether attackers can breach your defenses but whether your team detects and responds effectively when they do.

Passing criteria: Documented incident response plan updated within 12 months, tabletop exercise conducted within the past 6 months, all contact information verified, regulatory notification requirements documented for each applicable framework.

13. Physical Security Controls

Network security assessments that ignore physical security miss a critical attack vector. Physical access to server rooms, network closets, and workstations can bypass every digital control you have implemented. Social engineering attacks that gain physical access to facilities are alarmingly effective against small businesses that lack formal visitor management procedures.

Verify that server rooms and network closets are locked and that access is restricted to authorized personnel. Check that access logs are maintained and reviewed. Ensure that network jacks in public areas such as lobbies, conference rooms, and break rooms are either disabled or on an isolated VLAN. Verify that screens lock automatically after a maximum of 5 minutes of inactivity and that clean desk policies are enforced for areas handling sensitive information.

Review disposal procedures for old equipment. Hard drives, SSDs, and devices being decommissioned must be securely wiped or physically destroyed. Petronella Technology Group provides certified data destruction services that include a certificate of destruction for compliance documentation.

Passing criteria: Server room access restricted and logged, unused network jacks disabled, automatic screen lock enforced, documented equipment disposal procedures with certificates of destruction.

14. Third-Party and Vendor Risk Assessment

Your network security is only as strong as the weakest vendor with access to your systems. Third-party risk has been the root cause of some of the largest breaches in history, from the Target breach through an HVAC vendor to the SolarWinds supply chain attack. Small businesses often grant vendors broad network access without conducting any security evaluation.

Inventory every third party with access to your network, data, or systems. This includes IT service providers, software vendors with remote access, cloud service providers, payment processors, and any contractor with VPN or RDP access. Evaluate each vendor's security posture through security questionnaires, SOC 2 reports, or independent assessments. Verify that vendor access is limited to the minimum necessary and is revoked promptly when the engagement ends.

Review data sharing agreements. Every vendor that processes, stores, or transmits your sensitive data should have a signed agreement specifying security requirements, breach notification obligations, and data handling procedures. For HIPAA-covered entities, Business Associate Agreements are legally required for any vendor handling protected health information.

Passing criteria: Complete vendor inventory maintained, security assessments completed for all critical vendors, vendor access limited and regularly reviewed, data sharing agreements in place for all vendors handling sensitive data.

15. Security Awareness Training Evaluation

Technology controls are necessary but insufficient. The human element remains the most exploited vulnerability in any organization. Security awareness training transforms employees from the weakest link into an active layer of defense, but only if the training program is effective, relevant, and ongoing.

Verify that all employees complete security awareness training upon hire and at least annually thereafter. Training should cover phishing recognition, password hygiene, social engineering tactics, physical security awareness, data handling procedures, and incident reporting. Check that training content is updated to reflect current threats, not recycled content from years past.

Measure training effectiveness through phishing simulations, knowledge assessments, and incident reporting metrics. An effective program should demonstrate declining phishing click rates, increasing report rates, and faster reporting times over successive quarters. Training should be role-specific: employees handling financial transactions need training on business email compromise, healthcare staff need HIPAA-specific training, and IT staff need technical security training beyond general awareness.

Passing criteria: 100 percent of employees trained within the past 12 months, phishing simulation click rate below 5 percent, role-specific training for high-risk positions, training content updated to reflect current threats.

How to Prioritize Your Assessment Findings

Completing the checklist will almost certainly produce a list of findings. The question is not whether you will find gaps but how to prioritize remediation when budget and time are limited. Not all findings carry equal risk, and treating them equally leads to wasted resources on low-impact items while critical vulnerabilities remain unaddressed.

Use a risk-based prioritization framework. For each finding, evaluate two factors: the likelihood of exploitation and the business impact if exploited. A critical vulnerability on an internet-facing system with no compensating controls is a higher priority than a medium vulnerability on an isolated internal system protected by network segmentation. Focus first on findings that an external attacker could exploit without authentication, then move to findings that require internal access, and finally address hardening improvements that reduce risk but do not represent immediate exploitable vulnerabilities.

Create a remediation roadmap with three tiers. The first tier covers critical findings that must be addressed within 30 days: unpatched internet-facing vulnerabilities, missing MFA on remote access, exposed credentials, and default passwords. The second tier covers high-severity findings to address within 90 days: network segmentation gaps, logging deficiencies, and missing backup testing. The third tier covers medium and low findings to address within 180 days: policy updates, training improvements, and documentation gaps.

When to Conduct Network Security Assessments

At minimum, conduct a comprehensive network security assessment annually. However, treating assessments as a once-a-year exercise is insufficient for the current threat landscape. Specific events should trigger an immediate reassessment outside the regular cycle:

• Office moves or expansions that change the physical network topology
• Mergers and acquisitions that integrate new networks and systems
• Major technology deployments such as cloud migrations, ERP implementations, or new line-of-business applications
• Security incidents that may indicate broader compromise requiring investigation
• Compliance audit preparation to identify and remediate gaps before auditors arrive
• Cyber insurance renewals where carriers increasingly require current assessment documentation
• Significant personnel changes especially in IT or leadership roles with elevated access
• Vendor changes when onboarding new service providers with network access

Organizations handling regulated data should consider quarterly assessments for high-risk areas such as internet-facing systems and access controls, with comprehensive annual assessments covering the full checklist.

The Cost of Doing Nothing

Small business owners often defer network security assessments because of perceived cost. The assessment itself is an investment, but the cost of not assessing is orders of magnitude higher. Consider the math: a professional network security assessment for a small business typically costs between $3,000 and $15,000 depending on scope and complexity. The average cost of a data breach for a small business is $164,000, and that figure does not account for lost business, reputational damage, or the personal liability that can attach to business owners who failed to implement reasonable security measures.

Regulatory penalties add another dimension. HIPAA violations can result in fines of up to $2.13 million per violation category per year. CMMC non-compliance means losing the ability to bid on Department of Defense contracts. PCI DSS non-compliance can result in fines of $5,000 to $100,000 per month. State privacy law violations carry their own penalty schedules. In every case, the ability to demonstrate that you conducted regular security assessments and acted on findings is a significant mitigating factor in enforcement actions.

Frequently Asked Questions

How long does a network security assessment take?

A typical assessment for a small business with 25 to 100 endpoints takes 5 to 10 business days, including scanning, analysis, and report generation. Larger or more complex environments may require additional time. PTG provides a detailed timeline and scope document before beginning any assessment.

Will the assessment disrupt our normal business operations?

Assessments are designed to minimize disruption. Vulnerability scanning is typically conducted during off-hours or with throttled bandwidth to prevent performance impact. Penetration testing activities are coordinated in advance with your team. The only assessment activity that may require brief downtime is backup recovery testing, which can be scheduled for maintenance windows.

How often should we conduct a network security assessment?

At minimum, conduct a comprehensive assessment annually. Organizations handling regulated data such as healthcare information, payment card data, or controlled unclassified information should assess quarterly for high-risk areas. Additional assessments should be triggered by major changes such as office moves, mergers, technology deployments, or security incidents.

What is the difference between a vulnerability assessment and a penetration test?

A vulnerability assessment identifies known vulnerabilities across your environment through automated scanning and manual review. A penetration test goes further by attempting to exploit those vulnerabilities to demonstrate real-world impact. Both are valuable and serve different purposes. Vulnerability assessments provide breadth of coverage, while penetration tests provide depth of validation.

Do we need a network security assessment if we use cloud services?

Absolutely. Cloud environments introduce their own set of security risks including misconfiguration, excessive IAM permissions, and exposed storage. The shared responsibility model means your cloud provider secures the infrastructure, but you remain responsible for securing your configuration, data, and access controls. Cloud-specific assessment is a critical component of any comprehensive network security evaluation.

Can a network security assessment help with cyber insurance?

Yes. Cyber insurance carriers increasingly require documented security assessments as a condition of coverage. Assessment reports demonstrate due diligence and can help qualify for lower premiums. More importantly, having current assessment documentation and demonstrated remediation of findings helps ensure that claims are not denied for failure to maintain reasonable security controls.

What qualifications should a network security assessor have?

Look for assessors with recognized certifications such as CISSP, CISM, CEH, or OSCP, combined with documented experience in your industry. At PTG, our assessments are led by Craig Petronella, an NC Licensed Digital Forensics Examiner with 24+ years of experience and 15 published books on cybersecurity. Industry-specific expertise matters because assessors must understand both the technical vulnerabilities and the regulatory context of your environment.

What happens after the assessment is complete?

PTG delivers a comprehensive report including an executive summary, detailed technical findings, risk ratings, and a prioritized remediation roadmap. We schedule a review meeting to walk through findings, answer questions, and help you develop a remediation timeline. For clients who need ongoing support, our managed IT services and vCISO programs provide continuous monitoring and security program management.
