Municipality of Westerkwartier
Local Government · Netherlands · ~650 employees · 23 locations
Challenge
Westerkwartier needed to comply with NIS2 (Article 21–23) across 23 physical sites, each with its own network, but was managing compliance using disconnected spreadsheets and four separate tools.
Solution
Gatekeeper replaced their network scanner, CMDB, compliance tracker, and ticketing system. Automated discovery populated the CMDB in 48 hours, and the NIS2 framework template generated audit-ready evidence packages for their regional regulator.
Results
- NIS2 compliance score from 41% to 94% in six weeks
- Four legacy tools decommissioned
- Audit preparation reduced from three weeks to one afternoon
The auditor said it was the best-prepared NIS2 evidence package they had seen from any municipality in our region.

Request Call →Waternet
Water Board / Critical Infrastructure · Netherlands · ~1,800 employees · OT & IT environments
Challenge
Waternet operates critical water treatment and distribution infrastructure with strict BIO (Baseline Informatiebeveiliging Overheid) requirements. Their OT network segments were completely invisible to existing IT tools.
Solution
Air-gapped Gatekeeper agents were deployed on the OT network segments. The CMDB auto-discovered 2,400+ devices across both IT and OT, and the BIO compliance template mapped directly to their existing controls.
Results
- Full visibility across IT and OT networks for the first time
- BIO compliance score improved from 58% to 91%
- Zero outbound connections from OT segments (air-gapped)
For the first time we can present one unified compliance report covering both our corporate IT and operational technology environments.

Request Call →University Medical Center Amsterdam
Healthcare · Netherlands · ~7,200 employees · 850+ connected medical devices
Challenge
UMC Amsterdam faced strict HIPAA and Dutch patient data protection (AVG) requirements across 12 hospital departments. Device discovery was incomplete, medical device changes were untracked, and compliance audits required manual evidence collection across fragmented systems.
Solution
Gatekeeper deployed remote agents across all 12 departments. Network discovery automatically inventoried all 850+ medical devices. The multi-framework compliance engine generated audit-ready evidence packages for both HIPAA and AVG requirements simultaneously.
Results
- Medical device inventory increased from 420 to 850+ tracked devices
- Regulatory audit preparation time reduced from 6 weeks to 3 days
- Zero security incidents from unknown devices (baseline: 2-3 per year)
Patient data security is non-negotiable. For the first time we have complete visibility of every device that can access patient records. The automated compliance reporting for HIPAA and AVG requirements eliminated weeks of manual audit preparation.

Request Call →Province of Fryslân
Provincial Government · Netherlands · ~900 employees · 8 sites
Challenge
Fryslân faced simultaneous audits for NIS2, BIO, and ISO 27001. Three different compliance frameworks, three different auditors, and evidence had to be prepared separately for each.
Solution
Gatekeeper’s multi-framework compliance engine mapped existing controls to all three frameworks simultaneously. Evidence packages were generated per framework with a single click.
Results
- Three regulatory frameworks managed from one platform
- Audit preparation for all three frameworks completed in one day
- Passed all three audits on first attempt
Our CISO required evidence packages for three regulators simultaneously. Gatekeeper generated audit-ready PDFs for each framework in under a minute. That alone justified the entire platform cost.
