Tenable One Vulnerability Management review

Tenable takes the top spot because it pairs the most widely known scanner, Nessus, with a cloud console that a small security team can buy without a sales cycle. Tenable One Vulnerability Management lists at $3,500 a year for 100 assets on Tenable's own buy page, and you can buy coverage for up to 250 assets online. Tenable describes the product as giving continuous visibility, built-in prioritization, deep vulnerability context and real-time reporting, and it sits inside the Tenable One exposure management platform, so you can later add attack surface management, cloud exposure, OT or patch management without changing vendors. Teams that must keep data on site can pick Tenable Security Center instead. The weak points are cost creep and complexity: web application scanning is a separate $6,790 subscription for five FQDNs, and the long list of Tenable products takes time to map to your needs. For a team that wants proven scanning plus a clear entry price, it is the safest first shortlist entry.

Who it is for
