Frequently Asked Questions
How long does ISO 27001 certification take?
Typical timeline is 6 to 12 months from gap assessment through Stage 2 certification audit, depending on your starting maturity and scope complexity.
What frameworks does ISO 27001 map to?
ISO 27001 maps extensively to NIST frameworks, GDPR, HIPAA, SOX, and SOC 2.
What changed in the 2022 revision?
ISO 27001:2022 restructured Annex A from 114 controls in 14 domains to 93 controls across 4 themes (Organizational, People, Physical, Technological), adding 11 new controls.
Is ISO 27001 required by law?
Not required by law directly, but many contracts, regulations, and customer requirements effectively mandate it. Certification demonstrates security maturity to customers, partners, and regulators.
How does ISO 27001 relate to SOC 2?
Both assess security controls, but ISO 27001 results in a formal certification while SOC 2 produces an attestation report. Many organizations pursue both for different audiences.
