Top external-posture risks for energy & utilities

These are the sector-specific gaps a SaaSFort scan flags first -- each maps to a NIS2 Article 21(2) measure.

Customer billing portals without HSTS / modern TLS
Exposed operational or grid-partner subdomains
No CAA / DNSSEC on the primary utility domain
Security headers absent on the self-service account area
Email authentication gaps enabling utility-bill phishing

The 10 NIS2 Article 21(2) measures

Every in-scope entity must implement all ten. SaaSFort produces external evidence for the technical measures (encryption, MFA, secured comms, vulnerability handling).

Incident handling (detection, response, 24h/72h BSI notification)
Business continuity, backup management & crisis management
Supply-chain security (§30 BSIG -- assess your vendors and sub-providers)
Security in acquisition, development & maintenance (incl. vulnerability handling)
Policies to assess the effectiveness of risk-management measures
Basic cyber hygiene practices & security training
Cryptography and encryption policies
Human resources security, access control & asset management
Multi-factor authentication, secured communications & emergency comms

Frequently asked questions

Is Energy & Utilities in scope for NIS2?

Energy & Utilities falls under "Energy (NIS2 Annex I — electricity, gas, district heating, hydrogen)". Entities of this type are typically treated as essential entities once they exceed the 50-employee or €10M-turnover threshold -- and NIS2 obligations also cascade through supply chains under §30 BSIG, so smaller vendors selling into in-scope customers are pulled in indirectly.

What does an external NIS2 scan check for energy & utilities?

It checks what an attacker and a BSI auditor see from outside the perimeter: TLS/SSL configuration, security headers, DNS/email authentication (SPF, DKIM, DMARC, DNSSEC, CAA), certificate hygiene, exposed panels, and known-vulnerable components -- mapped to NIS2 Article 21(2) and ISO 27001 Annex A. Common energy & utilities gaps: customer billing portals without hsts / modern tls.

Does this replace a full NIS2 audit?

No. An external posture scan is the fastest first step -- it gives you auditor-ready evidence of your external surface in 60 seconds. A full NIS2 programme also covers internal controls, governance and incident processes. SaaSFort produces the external-evidence portion that auditors ask for first.
