Excluding Known Vulnerability Scanners

A vulnerability scanner works by probing many hosts and ports, which looks like the reconnaissance an attacker performs. If you run a scanner that you trust, add it to SenseOn so that its authorised scanning is not raised as a scanning detection.


Adding a scanner

Go to Settings > Detections. There are three settings, and you can add a scanner to any of them:

Setting Use it when
Exclude IP addresses from scanning detections You know the IP address the scanner scans from.
Exclude host names from scanning detections You know the host name of the machine the scanner runs on.
Exclude subnets from scanning detections You know the subnet the scanner scans from, for example a pool of scanning appliances.

Each setting holds up to 100 entries.

You need the Admin role to change these settings.

  1. Open Settings > Detections.
  2. Choose the setting that matches how you identify the scanner, by IP address, host name or subnet.
  3. Add the scanner's IP address, host name or subnet.

If you identify the scanner more than one way, for example a host with a fixed IP address, you can add it to more than one setting.

⚠ Only add scanners you run and trust. A host listed in these settings is not flagged for scanning activity. If that host were ever compromised, its scanning would not raise a detection. Keep the lists limited to scanners you operate, and remove an entry when the scanner is retired.


  • Penetration tests and red team exercises are different from routine scanning. Tell SenseOn about them in advance, as described in Red-Team / Pentesting Guidance.
  • Data Connectors can ingest results from vulnerability management tools such as Qualys, Rapid7 InsightVM and Tenable.
