New API Gateway Functionality

  • The following new fields add new API Gateway request functionality for Discover, and are added at stability index 1.1 - Experimental (Active Development):
    • Discover requests
      • mutation.discoverInterfaceAddLabel - add a label to a Discover interface
      • mutation.discoverInterfaceRemoveLabel - remove a label from a Discover interface
      • mutation.discoverLabelCreate - create a Discover label
      • mutation.discoverLabelDelete - delete a Discover label
      • query.discoverInterfaces - retrieve Discover interfaces
      • query.discoverLabels - retrieve Discover labels
  • For the best results, install API Gateway 1.8.77 or later. For more information, see

Known Issues

  • Windows 11 ARM is not supported for:
    • Level 3 and 4 distributed scans that use Nmap
    • Satellite scanning with the Windows 11 ARM as the satellite
  • To address gaps in visibility for Windows 11 ARM-based subnets, use a supported OS satellite for that subnet.
  • Gateway will report IsManaged inaccurately as True when computerId is omitted
  • If endpoints have both Level 2 Ping Scans and Level 4 NMAP scans enabled the endpoint can get removed from their network connections by Network Security Applicances. A reboot of the affected endpoint will reconnect the device. No endpoint should have both Level 2 and Level 4 scans enabled to avoid this condition.
