Why the NIST Zero Trust Architecture No Longer Requires Decryption by Jonathan Barrett

The document outlines NIST Zero Trust Architecture (SP 800-207) principles and explains why decrypting traffic is discouraged, emphasizing that effective detection can be achieved through metadata analysis and machine learning, especially amid widespread adoption of TLS 1.3 and related security mechanisms. It highlights the need for modern NDR to provide visibility across encrypted traffic, devices, and identities without agents, and positions Vectra’s AI-driven, FIPS-compliant Cognito Platform as a turnkey solution supporting Zero Trust.
