From paper compliance to automation: How a GRC simplifies the National Security Scheme (ENS)

For many organizations, the National Security Scheme (ENS) evokes the image of hundreds of static documents: policy manuals, procedures archived in shared folders, and giant spreadsheets attempting to track more than 75 security measures.

This documentation-heavy approach not only drains the resources of cybersecurity and compliance teams, but also fails to uphold the guiding principle of Royal Decree 311/2022: security must be understood as an integral process and risk management must constitute a continuous and permanently updated activity.

Attempting to pass a biennial audit in MEDIUM or HIGH categories relying on static documents leads to operational failure. The alternative? Shift compliance from an administrative task to a technical perspective using GRC (Governance, Risk, and Compliance) platforms like Riskblade.

Why has traditional ENS document management collapsed?

The ENS regulatory framework is not a simple checklist. Its structure requires connecting four complex layers:

1. The Security Policy and Regulations (org.1 to org.4): Organizational framework requiring formal role assignment and clear separation of responsibilities.
2. Risk Analysis (op.pl.1 and Art. 14): For MEDIUM and HIGH categories, the regulation requires semi-formal (R1) or formal (R2) risk analyses based on recognized methodologies.
3. Statement of Applicability (Art. 28.2): The living document that formalizes the selected security measures signed off by the Chief Information Security Officer.
4. Objective Evidence (Annex III): Technical proof that each measure is implemented and subject to regular review.

Trying to keep these four layers alive and cross-referenced using traditional tools causes paralysis by documentation. When a certification audit arrives, half of the risk matrices are out of sync with the actual asset inventory (op.exp.1), leading to non-conformity findings.

The technical side of compliance: How a GRC transforms the ENS

A modern GRC platform flips the equation: instead of writing documents to justify technology, it uses technical data to automatically generate compliance.

A. Continuous risk analysis and management (Art. 7 and 14)

Instead of annual spreadsheet reviews, a GRC automates asset inventory and links threats and safeguards in real time. Whenever a new asset or vulnerability appears, the system automatically recalculates residual risk, fulfilling the legal requirement for continuous reassessment.

B. Dynamic Statement of Applicability (Art. 28.2)

Keeping the Statement of Applicability up to date usually demands dozens of hours of manual work. A GRC tool generates this document automatically based on the system category (BASIC, MEDIUM, or HIGH) and the adopted risk treatment decisions.

C. Evidence orchestration for the auditor (Annex III)

The Technical Security Audit Instruction establishes that the audit team must request objective evidence to evaluate the degree of compliance. The GRC acts as a centralized evidence repository where each Annex II control is automatically linked to its technical proof (vulnerability reports, configuration logs, or code audit reports).

D. Traceability of CMM Maturity levels (Annex II – Section 6)

The ENS requires proving that measures reach maturity level L3 (Defined process) in MEDIUM category or L4 (Managed and measurable) in HIGH category. A GRC monitors systematic metrics (op.mon.2) on measure effectiveness, objectively proving CMM maturity to auditors.

Riskblade: intelligent automation for a simplified ENS

At Riskblade, we designed our GRC solution to eliminate 80% of the bureaucratic burden associated with the National Security Scheme, allowing teams to focus on real security:

• Automatic mapping of Annex II controls: Immediate assignment of 75+ ENS measures based on system category and affected dimensions (Confidentiality, Integrity, Traceability, Authenticity, and Availability).
• Frictionless risk management: Automated asset catalog, threat mapping, and safeguard association aligned with Magerit and ENS methodologies.
• Evidence centralization and lifecycle management: Collection, approval, and expiration tracking for audit evidence to arrive at biennial audits with 100% of documentation ready.
• Dashboard for CISOs and Auditors: Real-time visibility into the security system compliance status, facilitating easy export of the security status report and Statement of Applicability.

Compliance with the National Security Scheme shouldn’t be a burden that paralyzes tech teams. Turning the ENS into an automated, living, technical process using a GRC like Riskblade lets you move past the “paper illusion” to a robust, efficient security posture ready for any audit.
