Tenable
Tenable is the market leader in vulnerability management with Nessus (the most widely deployed vulnerability scanner) and Tenable One (exposure management platform). Tenable.io starts around $5,000/year for 65 assets; enterprise exposure management pricing scales with asset count.
Tenable is the safe choice for vulnerability management when your security team needs coverage breadth and established compliance reporting. Qualys is worth pricing for large enterprises - competition between the two often produces better terms. Microsoft Defender Vulnerability Management covers most of the same ground for Windows-centric shops at a lower marginal cost.
