What is zero trust security in simple terms?

Zero trust is a security approach that assumes no user, device, or network connection should be trusted by default. Instead of relying on a network perimeter (like a VPN or firewall) to keep bad actors out, zero trust verifies the identity and security posture of every user and device for every access request. Think of it as requiring a badge scan at every door in your building, not just the front entrance. PTG implements zero trust architectures that make this verification seamless for users while dramatically reducing your attack surface.

How long does a zero trust implementation take?

Zero trust is a maturity journey, not a single deployment. PTG typically delivers the initial assessment and roadmap within 2-4 weeks, implements the identity pillar (MFA, conditional access) within 30-60 days, and progresses through network microsegmentation, device trust, and continuous monitoring over 6-18 months depending on environment complexity. Each phase delivers standalone security value, so you do not have to wait for full implementation to see results.

Do we need to replace all our existing security tools?

No. Zero trust is an architecture and philosophy, not a single product. PTG builds zero trust on top of your existing investments wherever possible — integrating with your current firewalls, identity providers, endpoint protection, and cloud platforms. We identify gaps that require new capabilities and recommend solutions that complement rather than replace your existing security stack.

Is zero trust required for CMMC, HIPAA, or SOC 2 compliance?

While none of these frameworks explicitly mandate "zero trust" by name, they all require the individual controls that zero trust implements: multi-factor authentication, least-privilege access, network segmentation, continuous monitoring, and data protection. Implementing zero trust satisfies these requirements comprehensively and positions your organization ahead of evolving regulatory expectations. Federal contractors should note that Executive Order 14028 mandates zero trust adoption for federal agencies and their supply chains.

Will zero trust slow down our employees?

A well-implemented zero trust architecture should be nearly invisible to users during normal operations. Modern conditional access policies evaluate risk signals in real time — if a user is on a managed device, from a known location, with healthy endpoint status, authentication happens seamlessly. Users only encounter additional verification steps when risk signals change: new devices, unusual locations, or anomalous behavior patterns. PTG tunes policies to minimize friction while maintaining security.

What is the difference between zero trust and a VPN?

A VPN grants broad network access once authenticated — once you are connected, you can typically reach many resources on the corporate network. Zero trust grants granular, application-specific access based on identity, device health, and context. A VPN trusts you once at the front door; zero trust verifies you at every resource you attempt to access. PTG helps organizations transition from VPN-based remote access to zero trust network access (ZTNA) that provides more granular control with a better user experience.

Zero Trust Security

Zero Trust Security Never Trust, Always Verify

The traditional security perimeter is gone. We implement zero trust architectures aligned with NIST SP 800-207 that verify every user, device, and connection before granting access -- every time.

Zero Trust Implementation Capabilities

Comprehensive zero trust covering all five CISA pillars: Identity, Devices, Network, Applications, and Data.

Identity and Access

MFA for all users with conditional access policies based on risk signals
SSO for SaaS and on-premises applications with Azure AD, Okta, or Duo
Privileged access management and identity governance for joiners/movers/leavers

Network and Endpoints

Microsegmentation that eliminates flat networks and restricts lateral movement
Device posture assessment and compliance verification before granting access
Cloud zero trust for AWS, Azure, and GCP with workload identity and CASB

NIST SP 800-207 Aligned

The Five Pillars of Zero Trust

Covering all five pillars defined by the CISA Zero Trust Maturity Model.

Identity

Strong authentication, conditional access, identity governance, and continuous session validation for every user and service account.

Devices

Device posture assessment, EDR, certificate-based identity, and compliance enforcement before granting access.

Network

Microsegmentation, encrypted communications, software-defined perimeters, and elimination of implicit trust zones.

Applications

Application-layer access controls, API security, secure development practices, and runtime authorization checks.

Data

Data classification, encryption at rest and in transit, DLP enforcement, and access logging regardless of location.

The Transformation

Perimeter Security vs. Zero Trust

Before -- Perimeter Security

Trust Inside the Firewall

Once past the perimeter, users and devices have broad access to network resources.

Free Lateral Movement

Attackers who breach one system move freely to domain controllers, databases, and backups.

VPN as Single Gate

Remote access through VPN grants network-level access rather than application-level access.

After -- Zero Trust

Verify Every Request

Every access request is authenticated and authorized regardless of network location.

Contained Blast Radius

Microsegmentation ensures a compromised system cannot reach other resources without additional verification.

Application-Level Access

Users access only the specific applications they need, not the entire network.

FAQ

Frequently Asked Questions

What is zero trust security?

Zero trust is a security model based on "never trust, always verify." Instead of assuming everything inside your network is safe, it requires continuous verification of every user, device, and application before granting access to any resource.

Do I need to replace all my existing security tools?

No. Zero trust is an architecture, not a single product. We integrate with your existing firewalls, identity providers, EDR, and cloud platforms to implement zero trust principles across your current infrastructure.

Which compliance frameworks require zero trust?

CMMC 2.0 requires MFA and least-privilege access. HIPAA mandates minimum necessary access. PCI DSS 4.0 requires targeted risk analysis for access exceptions. Federal Executive Order 14028 mandates zero trust for government agencies and contractors.

How long does zero trust implementation take?

Zero trust is a phased journey, not a one-time project. We deliver quick wins (MFA, conditional access) in weeks, with microsegmentation and full architecture maturity over 6-12 months.

Will zero trust slow down my users?

Modern zero trust implementations use risk-based authentication that is transparent to users during normal operations. Step-up verification only occurs when risk signals change, keeping productivity high while security stays strong.

Does zero trust work for remote and hybrid workers?

Absolutely. Zero trust was designed for the reality of remote work. It replaces VPN-based network access with identity-based application access, providing better security and a better user experience for distributed teams.
