Frequently Asked Questions

How long does ISO 27001 certification take?
For most SMBs, 3-6 months from starting to certification audit. This includes establishing the ISMS, implementing controls, running an internal audit, and completing the Stage 1 and Stage 2 certification audits. Companies with existing security practices can move faster. Companies starting from scratch should plan for closer to 6 months.
How much does ISO 27001 certification cost?
Total cost varies by company size. For a 20-50 person company, expect $15,000-$40,000 including consulting, tooling, and certification body audit fees. The certification audit itself typically costs $5,000-$15,000 depending on scope and auditor. Annual surveillance audits cost roughly half the initial audit fee.
What is the difference between ISO 27001:2013 and ISO 27001:2022?
The 2022 revision restructured Annex A from 114 controls in 14 domains to 93 controls in 4 themes (Organizational, People, Physical, Technological). It added 11 new controls covering areas like threat intelligence, cloud security, and data masking. Organizations certified under the 2013 version had to complete the transition by October 2025; certificates against the 2013 revision are no longer valid and all new certifications are issued against the 2022 revision.
Do I need ISO 27001 if I already have SOC 2?
It depends on your market. SOC 2 is recognized primarily in North America. ISO 27001 is the global standard, particularly important for European customers and contracts. Many companies pursuing international business need both. The overlap is significant - roughly 60-70% of controls map between the two frameworks.
