Security teams can use vulnerability scanning software to assess systems for weaknesses; the listed criteria show how the options differ in coverage and operation. Start by comparing supported targets and asset limits, then consider authenticated and continuous scanning. Compliance frameworks and deployment model offer additional ways to distinguish entries. The ranking begins with Intruder, OpenVAS, and Vornin, followed by ManageEngine Vulnerability Manager Plus and NSAuditor AI. Free-plan availability and paid-from pricing provide cost context. Compare those details with the systems you need to scan and the scanning approach that fits your work.
31 vulnerability scanning software ranked on what their makers publish — plans and prices, free tiers, platforms and the facts on their own pages.
