In a world where cyberattacks, data protection, and the continuity of digital services are becoming increasingly important, security has become a fundamental requirement for every organization.

At Luce IT, we have achieved certification under Spain’s National Security Framework (ENS) at the HIGH level, the highest security category established by this Spanish regulatory framework.

This achievement marks another step forward in our commitment to information security and strengthens our ability to deliver technology projects that demand high standards of protection, control, and trust.

But what exactly does this certification mean? And why does it matter to our clients?

What is Spain’s National Security Framework (ENS)?

The National Security Framework (ENS) is Spain’s regulatory framework establishing the principles, requirements, and measures needed to protect information systems used by public administrations and the private service providers to which it applies.

Regulated by Royal Decree 311/2022 of May 3, its purpose is to ensure that data and digital services are adequately protected against threats, unauthorized access, alterations, and disruptions.

Put simply, the ENS establishes how information systems must be protected to operate securely and reliably.

To achieve this, it focuses on five fundamental security dimensions:

• Confidentiality: ensuring that information can only be accessed by authorized individuals.
• Integrity: protecting data against unauthorized modifications or alterations.
• Availability: ensuring that systems and services are accessible when needed.
• Authenticity: verifying the identity of users and the origin of information.
• Traceability: enabling relevant activities to be recorded and monitored.

These dimensions help organizations assess risks and establish the security measures required for each system.

What does ENS HIGH-level certification mean?

The ENS establishes three security categories: BASIC, MEDIUM, and HIGH. These categories are determined by the potential impact of a security incident on an organization’s information systems.

The HIGH category represents the most demanding level of security requirements and applies to systems where a security incident could have serious or very serious consequences.

Achieving this certification requires successfully completing an independent audit that assesses compliance with the security measures applicable to the systems covered by the certification.

It goes far beyond simply implementing cybersecurity tools. It also requires organizational procedures, risk assessments, access controls, business continuity measures, and mechanisms for monitoring and responding to security incidents.

That is why achieving ENS HIGH-level certification demonstrates compliance with particularly demanding information security requirements.

What does ENS HIGH-level certification guarantee for our clients?

When a company entrusts its data, applications, or digital services to a technology provider, it needs to know that security is embedded in the way that provider operates.

ENS HIGH-level certification provides independently audited assurance of compliance with demanding security requirements for the systems and services included within its scope.

Information protection

The ENS establishes measures to protect data against unauthorized access, improper alterations, and potential loss.

This is particularly important when handling sensitive business information or delivering services that require high levels of protection.

Access control and traceability

The certification requires appropriate mechanisms to manage who can access systems, what permissions they have, and how relevant activities are monitored.

Cyberthreat prevention and response

It includes requirements related to risk identification, vulnerability management, system monitoring, and security incident response.

Service continuity

Security also means being prepared to deal with unexpected disruptions.

The ENS includes backup, recovery, and business continuity measures designed to help reduce the impact of potential incidents on business operations.

Independent assessment

One of the most important aspects of this certification is that compliance is not based solely on a company’s own declaration.

Certified systems undergo a formal compliance audit and must continue to meet the applicable requirements throughout the certification’s validity period.

This does not mean that the risk of a security incident disappears, but it does provide objective evidence that the required security measures are being met.

How can you verify an ENS HIGH-level certification?

When selecting a technology provider, it is important to understand what a security certification means and how to verify it.

Here are the six key aspects you should check:

1. Security category: the certificate must explicitly state that it corresponds to the HIGH category.
2. Validity and certificate holder: the certificate must be valid and issued to the legal entity providing the services.
3. Certification scope: the scope must include the services being contracted.
4. Systems and activities: the certificate must identify the systems or activities covered, rather than simply referring to the company’s commercial name.
5. Certification body: the issuing organization must be authorized to certify compliance with the ENS.
6. Verifiable information: there must be evidence available to confirm the certification and its conditions.

You can find more information about this process on the official National Security Framework portal of Spain’s National Cryptologic Centre (CCN).

The most important detail is the scope of the certificate.

Certification applies to a defined scope of information systems. It does not necessarily mean that every product or service offered by a company is individually certified.

Why is ENS HIGH-level certification particularly important in the technology sector?

Organizations increasingly depend on cloud platforms, enterprise applications, integrations, digital services, and systems that manage large volumes of information.

In this environment, security cannot be addressed only when a problem arises. It must be considered from the earliest stages of solution design and throughout the entire technology lifecycle.

For a technology company, holding ENS HIGH-level certification provides several important advantages:

• Greater trust: it provides clients with independent evidence of compliance with security requirements.
• Readiness for demanding projects: it is particularly relevant in public-sector environments and services requiring enhanced security controls.
• Structured risk management: it promotes the continuous identification, assessment, and treatment of security threats.
• Continuous improvement: it encourages regular reviews of security procedures and protective measures.

Furthermore, ENS HIGH-level certification may be a requirement in certain public procurement procedures, depending on the characteristics of the services and their scope.
