Frequently Asked Questions

Is NIST CSF mandatory for SaaS companies?

NIST CSF is voluntary unless you're a federal contractor or in regulated industries referencing it. However, it's widely adopted as a security best practice framework globally.

How does NIST CSF relate to SOC 2?

NIST CSF provides a risk management framework; SOC 2 provides attestation. Many organizations map SOC 2 controls to NIST CSF categories. They're complementary, not competing.

What implementation tier should SaaS companies target?

Most mature SaaS companies target Tier 3 (Repeatable) or Tier 4 (Adaptive). Start by assessing current state, then create a roadmap based on risk tolerance and resources.
