⏱️ Estimated reading time: 4 minutes
Regulation No. 756/2026, of 22 June, has been published, implementing the new Legal Framework for Cybersecurity in Portugal. This regulation operationalises several obligations provided for in Decree-Law No. 125/2025, the legal instrument that transposed the NIS2 Directive into Portuguese law.
For companies, the message is clear: cybersecurity is no longer only a technical topic. It is becoming a demonstrable responsibility of governance, risk, evidence, incident response and operational resilience.
What changes with Regulation 756/2026?
Regulation 756/2026 defines practical rules for applying the new framework. The main topics include the CNCS electronic platform, self-identification and qualification of entities, the QNRCS, the risk matrix, minimum cybersecurity measures, residual risk management, communication of the person responsible for cybersecurity, the permanent point of contact, the annual report and incident notification.
In practice, organisations within scope will need to answer very concrete questions: are we within scope? Which compliance level applies? Which minimum measures must we implement? What evidence can we present? Are we prepared to notify and manage incidents within the legal deadlines?
Who is within scope?
The regulation applies to essential entities, important entities and relevant public entities, under the terms of the Legal Framework for Cybersecurity. The CNCS indicates that the new framework covers 17 sectors and the Public Administration, with requirements adjusted to the size of the entities and the importance of their activities.
Even companies that are not directly within scope may feel an indirect impact through customers, corporate groups, supply chains, contractual requirements, audits, insurance or third-party requirements.
Who needs to act within the company?
Implementing Regulation 756/2026 is not only the CISO’s responsibility. The CISO or the person responsible for cybersecurity may lead the strategy, but execution requires a multidisciplinary response.
Management bodies need to understand risk, approve priorities and ensure resources. The person responsible for cybersecurity should coordinate information security management and liaise with the board or senior management. The CIO and IT, network, systems and cloud teams need to ensure inventory, protection, monitoring, backups, vulnerability management and technological continuity.
GRC, compliance and risk teams should map obligations, monitor controls and manage residual risk. The SOC, CSIRT and incident response teams should prepare playbooks, escalation paths and notification criteria. Audit, legal, procurement, business continuity, HR and process owners also have a relevant role, because cybersecurity now depends on contracts, suppliers, training, recovery, control evidence and business decisions.
Critical points to prepare now
The first point is self-identification and qualification on the electronic platform. Entities within scope will need to be prepared to submit accurate information on their activity, sector, contacts and legal framing.
The second point is the QNRCS, the National Reference Framework for Cybersecurity. This reference framework brings legal compliance closer to recognised practices in information security, risk management, continuity, audit and governance.
The third point is residual risk management. After controls are applied, risk still remains. That risk must be known, documented, accepted, treated or monitored. This is a management decision, not only a technical decision.
The fourth point is the list of Internet-accessible assets. Organisations must know which assets are publicly exposed, including systems, services, versions, IPs, domains and dependencies. This requirement directly links compliance to attack surface management.
The fifth point is incident notification. The framework sets demanding deadlines: initial notification within 24 hours, an update where necessary within 72 hours, notification of the end of significant impact within 24 hours and a final report within 30 working days. These deadlines are only realistic if there is prior preparation, clear roles and available evidence.
What competences are needed to comply with Regulation 756/2026?
Preparing for Regulation 756/2026 requires different competences for different profiles. It is not enough to train only technical teams: compliance involves management, cybersecurity, IT, risk, compliance, continuity, audit, legal, procurement and business areas.
In this context, training gains strategic relevance. Behaviour provides learning paths aligned with these needs in the areas of Digital Compliance and Operational Resilience, Information Security, Cybersecurity and Forensics, Business Continuity, Risk Management, Audit and IT and Corporate Governance.
For management bodies, training in NIS2, governance, digital risk and resilience is relevant. For CISOs and cybersecurity leads, pathways in ISO 27001, ISO 27002 and ISO 27035, CISM, CISSP, CCISO and NIST Cybersecurity Framework stand out.
For professionals who need to structure, implement, operate or audit cybersecurity capabilities, the courses Cybersecurity Professional, Cybersecurity Lead Implementer and Cybersecurity Lead Auditor are particularly relevant.
For GRC, compliance and risk, priorities include NIS 2 Compliance Lead Manager, ISO 31000, ISO 27005 and residual risk management. For technical teams, SOC and forensics, critical competences include incident response, technical testing and digital investigation, with courses such as CEH — Certified Ethical Hacker and CHFI — Computer Hacking Forensic Investigator.
In this way, training moves beyond awareness and becomes a tool for turning legal obligations into consistent, auditable and sustainable practices.
Conclusion
Regulation 756/2026 marks a new phase for cybersecurity in Portugal. The challenge is not only to comply with technical requirements, but to demonstrate governance, risk, controls, evidence, incident response and continual improvement.
Technology is essential, but it is not enough. The difference will lie in the ability of people and teams to turn legal obligations into consistent, auditable and sustainable practices.
