Frequently asked questions

Is B2B SaaS & Cloud Providers in scope for NIS2?

B2B SaaS & Cloud Providers falls under "Digital infrastructure / Digital providers (NIS2 Annex II)". Entities of this type are typically treated as important 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 b2b saas & cloud providers?

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 b2b saas & cloud providers gaps: external posture gaps that fail enterprise security questionnaires.

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.
