Frequently Asked Questions

How long does a SOC 2 audit typically take for a B2B SaaS company?

The timeline varies depending on your organization’s size and readiness. Initial preparation typically takes 3-6 months, while the actual audit process takes 4-8 weeks. Type I audits (point-in-time) are faster than Type II audits (3-12 month period), but most enterprise customers require Type II reports.

What’s the difference between SOC 2 Type I and Type II audits?

SOC 2 Type I examines the design of your controls at a specific point in time, while Type II evaluates both the design and operating effectiveness of controls over a period (typically 3-12 months). Type II provides more assurance and is generally preferred by enterprise customers.

How much does SOC 2 compliance cost for a SaaS company?

Costs vary significantly based on company size, complexity, and current security maturity. Expect to invest $50,000-$200,000+ for the first year, including auditor fees, consulting costs, and internal resources. Ongoing annual costs are typically lower as processes mature.

Do I need to be SOC 2 compliant to sell to enterprise customers?

While not legally required, SOC 2 compliance has become a de facto requirement for B2B SaaS companies selling to enterprise customers. Many large organizations won’t consider vendors without current SOC 2 Type II reports.

How often do I need to renew my SOC 2 audit?

SOC 2 reports are typically valid for one year. Most companies undergo annual audits to maintain current compliance status and meet customer requirements for up-to-date reports.
