NIS2 and SASE: comply with the Cyber Resilience Act on one platform

Does your organisation fall under the Cyber Resilience Act?

NIS2 applies to two categories of organisations: essential entities and important entities. Both have similar technical obligations; the main difference is the level of supervision and the size of potential fines.

Essential entities include sectors like energy, transport, banking, healthcare, drinking water and digital infrastructure. Important entities cover postal and courier services, waste management, manufacturing of critical products, digital providers and research organisations. For both categories, the size threshold typically starts at 50 employees and 10 million euros annual turnover, though sector-specific exceptions apply.

A pragmatic first check: if your organisation is critical to operations of essential services, employs more than 50 people and operates across multiple sites, you are almost certainly in scope. Even when you are not directly in scope yourself, the supply chain obligations of your customers can effectively pull you in via contractual flow-down.

The three main obligations of NIS2

NIS2 imposes three overarching obligations on essential and important entities. Understanding them is the starting point for any technical compliance strategy.

Duty of care. The organisation must take appropriate technical and organisational measures to manage cyber risks. The directive lists ten minimum categories, including incident handling, business continuity, supply chain security, encryption and access control. These are not optional; the supervisor expects evidence.

Reporting obligation. Significant incidents must be reported to the national supervisor within strict deadlines: 24 hours for an early warning, 72 hours for an incident notification and one month for a final report. The clock starts at detection, not at containment.

Registration obligation. The organisation must register itself with the national authority. In the Netherlands this is the Digital Trust Centre. Registration includes designating a contact person, listing relevant sectors and providing technical contact information.

How SASE covers the technical NIS2 measures: the compliance mapping

Article 21 of NIS2 lists ten categories of technical and organisational measures. The interesting observation, when you map these to a mature SASE platform like Cato, is that seven of the ten are addressed by SASE as standard configuration.

Access control and identity management. ZTNA on the SASE platform delivers identity-driven, least-privilege access with continuous verification. Every access decision is logged with user, device, application and policy context, the exact evidence an auditor wants to see.

Encryption. All traffic over the SASE backbone is encrypted in transit. The single-pass engine decrypts only inside the cloud security stack for inspection and re-encrypts before forwarding. No plaintext traffic crosses public infrastructure.

Logging and incident detection. The platform's unified logging produces a single audit trail spanning network and security events. Detection capabilities include behavioural anomaly detection, threat intelligence correlation and AI-driven analysis through Cato CTRL.

Business continuity. The 4G/5G backup standard in the Cato Socket, combined with the global private backbone, provides connectivity resilience without manual failover.

Supply chain security. Third-party access via ZTNA is identity-bound and time-limited. Suppliers and contractors get exactly the access they need, for as long as they need it, fully logged.

The three categories that SASE does not directly address (governance, asset management, secure development practices) require process work alongside the platform. We document this in our implementation guide on Cato Networks implementation from intake to live network.

Supply chain security: the forgotten NIS2 obligation

Article 21(2)(d) explicitly requires supply chain security: securing relationships with direct suppliers and service providers. In practice this is where many organisations fall short. The classical solution, granting VPN access to suppliers and contractors, is exactly what NIS2 forces to be reconsidered.

ZTNA on the SASE platform changes this fundamentally. Every supplier session is identity-bound, scoped to specific applications, time-limited and continuously logged. Posture checks on the supplier's device verify endpoint hygiene before access is granted. Revocation is instant: closing access to a departed contractor is a console click, not a firewall rule update.

For organisations with dozens of third-party access relationships, this is the difference between "we have policies" and "we can prove the policies are enforced". The latter is what NIS2 supervisors expect.

Demonstrably compliant: one audit trail for all obligations

Compliance auditing is not about having the right technology; it is about being able to prove you do. The classical compliance challenge is that the evidence sits in twelve different tools (firewall logs, VPN logs, SIEM events, identity provider audit trails, etc.) and assembling a coherent narrative for an auditor takes weeks of manual work.

The platform approach inverts this. All traffic flows through the Cato single-pass engine, all decisions are logged with full context, all events feed into one data layer. An auditor query that previously required SQL across multiple log stores becomes a console filter. Reports that took weeks to compile become standard exports.

This is what we mean when we say compliance becomes a byproduct of the architecture rather than a separate workstream.

Momentum EMEA as NIS2 implementation partner

The technical platform is one half of the answer; the implementation partnership is the other. As EMEA's leading specialised Cato implementation partner, Momentum EMEA combines carrier-neutral underlay (the internet connectivity itself) and Cato SASE overlay (the security and access control) from one contract, one SLA and one team.

For NIS2 compliance specifically, this means a single accountable partner for the technical environment that produces the audit evidence. Our quarterly reviews include compliance posture reporting; our incident response procedures align with the 24/72-hour NIS2 reporting clock.
