What is NIS2 and who does it apply to in Portugal?

NIS2 is Directive (EU) 2022/2555, transposed into Portuguese law by Decree-Law no. 125/2025 of 4 December, which approved the new Legal Framework for Cybersecurity. It applies to essential and important entities in sectors considered critical or relevant, including energy, transport, healthcare, banking, digital infrastructures, public administration, among others. The framework entered into force on 3 April 2026.

Are ISO/IEC 27001 and NIS2 the same thing?

No. ISO/IEC 27001 is an international standard for information security management systems, whereas NIS2 is a European cybersecurity directive transposed into national law. Although they address related topics — such as risk, controls, incidents and responsibilities — they have different natures, scopes and purposes.

Does ISO/IEC 27001 certification help address NIS2?

Yes, it can help significantly. A well-implemented Information Security Management System — focused on risk management, controls, documentation, internal audit and continual improvement — supports a relevant part of the response to NIS2 and facilitates the demonstration of maturity. Even so, NIS2 includes its own regulatory requirements that require specific analysis, such as legal scope, entity classification, reporting obligations and interaction with the competent authorities.

What should professionals know about NIS2 and ISO/IEC 27001?

Information security, compliance, audit, risk and governance professionals need to understand both dimensions: the normative dimension, structured by ISO/IEC 27001, and the regulatory dimension, introduced by NIS2. Knowing how to articulate an Information Security Management System with the requirements of a cybersecurity legal framework — identifying overlaps, gaps and priorities — is an increasingly valued competence in the market.

What training covers NIS2 and ISO/IEC 27001?

Behaviour develops training in the areas of information security, cybersecurity and regulatory compliance. The learning paths cover both the normative dimension — implementation and auditing of Information Security Management Systems according to ISO/IEC 27001 — and the regulatory dimension, including the European cybersecurity framework and its practical application for different profiles and levels of responsibility.

Q: Is complying with ISO/IEC 27001 the same as complying with NIS2?

No. NIS2 and ISO/IEC 27001 do not represent the same obligation. ISO/IEC 27001 provides a management structure for organising information security. NIS2 establishes a legal framework with its own legal obligations for the entities covered. Having a certified ISMS is a highly relevant foundation, but it does not replace the analysis of the specific legal obligations applicable to the organisation.

Training in 2027: new standards, regulation and competences to develop

What has changed in quality, auditing, privacy, cybersecurity and artificial intelligence, and how to turn these changes into priorities for training in 2027.

⏱️ Estimated reading time: 9 minutes

Planning training in 2027 starts with a question: what has changed in the organisation’s standards and frameworks, risks and responsibilities?

ISO publications, ENISA’s threat landscape and European and national legislation help identify different needs. It is important to distinguish between published standards and frameworks, whose changes need to be analysed; applicable obligations, which require preparation for the responsibilities involved; and draft standards, which should be monitored without treating their requirements as final.

The aim is not to train everyone in the same topics, but to understand who needs to make decisions, implement, oversee or assess, and which competences they need.

NIS 2 in Portugal: Is appointing a cybersecurity officer enough?

Portugal’s new Cybersecurity Legal Framework distinguishes between the responsibilities of management bodies, the cybersecurity officer and the permanent point of contact. But how can organisations determine whether these functions are effectively coordinated?

⏱️ Estimated reading time: 4 minutes

For organisations subject to NIS 2 in Portugal, appointing a cybersecurity officer, identifying a permanent point of contact and communicating the required information to the competent authority are important steps towards compliance.

Can it therefore consider its cybersecurity governance arrangements to be adequately established?

Not necessarily. The formal appointment of responsible individuals is only one element of the governance model.

Decree-Law No. 125/2025 of 4 December, which transposes the NIS 2 Directive into Portuguese law, distinguishes between functions that must be coordinated but do not carry equivalent responsibilities.

NIS2 and ISO/IEC 27001: the same obligation or two different requirements?

NIS2 and ISO/IEC 27001 share a common vocabulary: risk, controls, incidents, responsibilities. But they do not have the same nature or the same purpose. Treating one as a substitute for the other is one of the most frequent misunderstandings, with practical consequences for organisations and professionals.

⏱️ Estimated reading time: 6 minutes

The entry into force of NIS2 reinforced an idea that many organisations already knew, but did not always treat with the necessary priority: cybersecurity is no longer merely a technical concern and has become a requirement of governance, risk management, operational continuity and management accountability.At the same time, many entities already had, or are preparing, information security management systems based on ISO/IEC 27001. This raises a frequent question:Is complying with ISO/IEC 27001 the same as complying with NIS2?The answer is clear: no. NIS2 and ISO/IEC 27001 are not the same obligation. But they are deeply related.
