March 2026 Nmap Engine Upgrade for Vulnerability Management (InsightVM) and Nexpose
As part of our ongoing efforts to strengthen security posture and support compliance efforts, we will be upgrading the integrated Nmap engine in both Vulnerability Management (InsightVM) and Nexpose as part of the upcoming March 30, 2026 product update.
Who is affected?
These changes will impact any assets hosting the Security Console or scan engines including:
- Local Scan Engines (installed alongside the Security Console)
- Distributed Scan Engines
You may be impacted if you run antivirus or firewall software on a system where Vulnerability Management (InsightVM)/Nexpose is installed.
If you’re using Managed Consoles or Hosted Scan Engines, no action is required.
What to expect
During previous upgrades, some antivirus tools have mistakenly flagged updated Nmap binaries as threats. This can result in quarantine or deletion, causing scan disruptions. Similar behavior may occur again with the upcoming release.
Recommended actions
To help ensure uninterrupted scanning operations, complete these steps before March 2, 2026:
Review antivirus and firewall settings
Ensure your antivirus or firewall allow the following directories, including all subfolders:
- Windows:
C:\Program Files\Rapid7\ - Linux:
/opt/rapid7/
Set up exclusions for future updates
If not already configured, configure exclusions for the Nmap engine for antivirus scanning on all relevant systems. This is important to prevent interference during future updates and to ensure uninterrupted scanning operations. These exclusions should be applied to:
- The InsightVM/Nexpose Security Console host machine
- All distributed Scan Engine host machines deployed in your environment
Refer to your antivirus documentation
For guidance on how to add exclusions or allowlist directories, consult your antivirus software’s documentation or support team.
Monitor your scans post-update
We recommend closely monitoring your scan jobs following the update. If you notice missing scans or encounter errors, check your antivirus logs to see if Nmap was blocked.
