SOC 2 VS ISO 27001
The main difference between SOC 2 and ISO 27001 is their scope and market focus. SOC 2 is primarily focused on North American markets and demonstrates security controls to customers, whereas ISO 27001 is an international standard that requires a comprehensive Information Security Management System (ISMS).
Choose **SOC 2** if your primary market is North America and you need to close deals with US-based enterprise customers quickly. Choose **ISO 27001** if you are expanding internationally or building a formal security program from the ground up.

Frequently Asked Questions
Can I do SOC 2 and ISO 27001 together?
Yes, and it is often recommended. There is about 70-80% overlap in controls. Doing them together can save time and audit fees compared to doing them separately.
Which one is harder to achieve?
ISO 27001 is generally considered more rigorous due to its documentation requirements for the ISMS. SOC 2 allows for more flexibility in defining your controls.
Do I need SOC 2 Type 1 before Type 2?
Not strictly required, but highly recommended. Type 1 checks design at a point in time, while Type 2 checks operating effectiveness over a period (usually 3-12 months).
