CNSA 2.0

What Is CNSA 2.0?

Commercial National Security Algorithm Suite 2.0 (CNSA 2.0) is the NSA's required cryptographic suite for National Security Systems, setting a 2027 horizon for adoption of quantum-safe algorithms in new acquisitions.

CNSA 2.0 sets concrete deadlines for post-quantum cryptographic adoption in defense and national security contexts. System integrators, OEMs, and contractors selling into NSS-adjacent markets need to identify quantum-vulnerable cryptography in their products and plan migrations within the CNSA 2.0 timeline — a task that requires cryptographic inventory across deployed artifacts.
