Understanding the NIS2 Requirements for Critical Infrastructure

The **NIS2 Directive** expands the scope of cybersecurity regulation in the EU to include "essential" and "important" entities across energy, transport, health, and digital infrastructure.

If you fall under NIS2, cybersecurity is now a board-level responsibility with strict penalties for non-compliance.

Key Changes from NIS1 to NIS2

**Broader Scope:** More sectors are included (e.g., waste water, food, space).

**Personal Liability:** Management bodies can be held personally liable for breaches.

**Supply Chain Security:** You are responsible for the security of your direct suppliers.

The Identity Mandate in NIS2

Article 21 of NIS2 specifically mandates "basic cyber hygiene practices," which include:

**Identity and Access Management (IAM)**

**Multi-Factor Authentication (MFA)**

**Continuous Monitoring**

You cannot be NIS2 compliant with weak passwords or shared admin accounts.

Step 1: Secure the Supply Chain (Identity Perspective)

**Vendor Access:** How do your suppliers access your network? VPNs? Citrix?

**Isolate and Monitor:** Treat supplier identities as high-risk. Monitor their sessions closely. Ensure they have the absolute minimum access required to fulfill their contract.

Step 2: Cyber Hygiene at Scale

**MFA Everywhere:** Not just for remote access. MFA should be on critical internal systems too.

**Password Policies:** Enforce strong policies, but better yet, move to passwordless (FIDO2) to eliminate the risk of phished credentials.

Step 3: Incident Reporting

NIS2 has strict reporting timelines (24 hours for early warning).

**Identity Context:** To report effectively, you need to know *who* was compromised. Was it an admin? Was it a service account? Cydenti's ITDR provides this context instantly.

How Cydenti Helps

Cydenti is built for the NIS2 era.

**Sovereign Hosting:** We help you meet data localization requirements.

**Supply Chain Visibility:** We map out the external identities (contractors, vendors) in your environment so you can assess their risk.

**Executive Dashboards:** We provide the high-level metrics your board needs to prove they are exercising their "duty of care" under NIS2.

Conclusion

NIS2 is raising the bar for Europe's digital shield. By prioritizing identity security, you address the most common vector of attack and ensure your organization contributes to the collective resilience of the continent.
