Tenable Nessus vs. Armor Agent

Built for security practitioners, by security professionals, Nessus products by Tenable are the de-facto industry standard for vulnerability assessment. Nessus performs point-in-time assessments to help security professionals quickly and easily identify and fix vulnerabilities, including software flaws, missing patches, malware, and misconfigurations - across a variety of operating systems, devices, and applications.

Armor Agent protects Windows and Linux servers wherever they run, in public cloud, private cloud, or on-premises environments, with a single, lightweight agent that installs with one line of code. The agent combines malware protection, intrusion prevention (IDS/IPS), file integrity monitoring, vulnerability scanning, patch monitoring, and behavioral threat detection into one deployment. Rather than stitching together multiple point tools, Armor Agent consolidates core workload security into a unified agent managed through the Armor platform. Armor Agent is available in two tiers.
