How to decide between SOC 2 and ISO 27001

Start with the words your buyers use. The wrong framework can be technically strong and still fail procurement.

01Read the customer requirement literally

If the questionnaire asks for SOC 2 Type 2, ISO 27001 will not automatically substitute. The reverse is also true.

02Map geography and deal size

US enterprise SaaS skews SOC 2. European and global supplier programs often skew ISO 27001.

03Reuse controls where possible

Many controls overlap. If you need both, design the evidence program once and choose auditors or consultants who understand both frameworks.

SOC 2 vs ISO 27001 questions

How buyers interpret the two frameworks.

Is SOC 2 better than ISO 27001?

βŒ„
