About Tenable Agents

Tenable Agents are lightweight, low-footprint, user space programs that you install locally on hosts to supplement network-based scanning or to provide visibility into gaps that network scanning misses. Tenable Agents collect vulnerability, compliance, and system data, and report that information back to a manager for analysis. With Tenable Agents, you extend scan flexibility and coverage. You can scan hosts and endpoints that intermittently connect to the internet without using credentials. You can also run large-scale concurrent agent scans with little network impact.

Tenable Agents help you address the challenges of network-based scanning, specifically for the assets where it's impossible or nearly impossible to collect information about your organization's security posture consistently. Network scanning typically occurs at selected intervals or during designated windows and requires systems to be accessible when a scan executes. If laptops or other transient devices are not accessible when a scan executes, they are excluded from the scan, leaving you unaware of vulnerabilities on those devices.

Once installed on servers, portable devices, or other assets found in today’s complex IT environments, Tenable Agents identify vulnerabilities, policy violations, misconfigurations, and malware on the hosts where they are installed and report results back to the managing product. You can manage Tenable Agents with Tenable Nessus Manager or Tenable Vulnerability Management.
