SnapKey helps you meet all requirements by providing automatic and documented access control.


Who is Covered by the CER Directive?

Sectors

  • Water supply (waterworks, treatment plants)
  • Healthcare & hospitals (acute and specialist clinics)
  • Digital infrastructure & data centers (telecom, server rooms)
