ENS Compliance & Certification: The Spanish Standard for Digital Sovereignty.
Compliance with the Esquema Nacional de Seguridad (ENS) — Royal Decree 311/2022 is often a contractual requirement to work with Spanish public administration, and a strong signal of security maturity. We help you achieve audit-ready compliance for Basic, Medium and High categories.
What RD 311/2022 changes in practice
The ENS update via Royal Decree 311/2022 reflects a more demanding threat landscape. For many organizations, the biggest shift is moving from “point-in-time compliance” to a model that expects continuous oversight.
At Hard2bit, we deliver a pragmatic roadmap so the certification process does not block operations — it strengthens them through measurable controls, governance, and evidence.
NIS2 alignment
We align ENS controls with European requirements to reduce duplicated effort and improve traceability.
Audit readiness
We support you end-to-end: scoping, evidence, remediation and preparation for an accredited conformity assessment.
ENS security dimensions
ENS evaluates security across key dimensions that we assess in depth:
- Confidentiality Information is accessible only to authorized individuals.
- Integrity Assurance that information has not been altered in an unauthorized manner.
- Availability Access to services and systems when needed (continuity).
- Authenticity & Traceability Unambiguous identification and logging of relevant actions.
System categorization
The technical requirements depend on the nature and impact of the information and services involved.
| Category | Risk profile | Audit requirement |
|---|---|---|
| Basic | Low-impact systems. Supervised self-assessment. | Every 2 years (self-assessment) |
| Medium | Moderate impact on critical services or sensitive data. | External audit (mandatory) |
| High | Essential systems, critical infrastructures or highly protected data. | External audit (highest rigor) |
