FAQ

How long does FedRAMP authorization take?

Timelines vary by baseline and maturity; many first-time Moderate efforts run roughly 12–24 months including remediation.

Can we reuse SOC 2 evidence for FedRAMP?

Often partially—cross-map controls in a GRC platform, then close FedRAMP-specific gaps (SSP depth, ConMon, federal inheritance).
