Frequently Asked Questions

Common questions about SOC 2 and ISO 27001

Can I get both SOC 2 and ISO 27001 certifications?

Yes, many companies choose to implement both frameworks. They complement each other well - SOC 2 for US customers and ISO 27001 for international markets. The good news is that there's significant overlap between the frameworks, so achieving one makes the other much easier.

Which one is easier to implement?

SOC 2 is generally considered easier and faster to implement. It has fewer requirements and can be completed in 3-6 months compared to 6-12 months for ISO 27001. However, the "easier" choice depends on your specific needs and customer requirements.

Do I need both Type I and Type II for SOC 2?

Start with Type I to establish your control design, then move to Type II for ongoing effectiveness. Most enterprise customers require Type II, but Type I is a good first step that demonstrates commitment to security while you build operational maturity.

How often do I need to renew my certifications?

SOC 2 requires annual audits for both Type I and Type II. ISO 27001 requires annual surveillance audits with a full recertification every 3 years. Both frameworks require continuous monitoring and improvement between audits.

Which certification do enterprise customers prefer?

US enterprises typically prefer SOC 2, while international companies often require ISO 27001. Many global enterprises now ask for both. Research your target customers' requirements before deciding which framework to pursue first.
