ENS — Spain's National Security Framework

The mandatory security framework for the Spanish public sector and its suppliers, with three categories matched to risk.

What is ENS?

The Esquema Nacional de Seguridad (ENS), updated by Royal Decree 311/2022, establishes the security policy for the use of electronic means by Spanish public administrations and the private entities that provide them services.

ENS classifies systems into Basic, Medium and High categories and structures controls across the security dimensions of confidentiality, integrity, availability, authenticity and traceability.
