      What are the network configuration requirements?

      Public network access

      Communication outbound is required for the instance to function properly on different TCP ports. This is necessary for daily updates of new vulnerability tests, participating in software updates provided by Holm Security, and ensuring the system's health state.

      The system only requires outbound access to these public endpoints (e.g., no inbound access is required). If your on-premise technical use case differs, please contact your respective Holm Security's Technical Sales or Customer Success Manager.

      Outbound IP network access to Holm Security endpoints:

      • IPv4: 185.163.84.0/22
      • IPv6: 2a0b:6800::/29
      • Ports:
        • TCP 443
        • TCP 8022

      Outbound network access for 3rd party services

      All service endpoints below are configurable but are required for the system to work properly

      • NTP: UDP 123
      • DNS: TCP/UDP 53

      Service & port definitions

      Information about each port and service that is related to the running system.

      Depending on where your system's end users are and where you place scanner appliances in your network, you might need to open up access to these ports.
