Instead of Intruder
Intruder alternatives
Intruder combines continuous vulnerability scanning for infrastructure, web apps, APIs, and cloud environments with remediation guidance. It ranks issues by exploit likelihood and threat intelligence, checks for emerging risks within hours, and offers authenticated application testing. The free plan covers five infrastructure targets with weekly external scans, but excludes web apps; internal target scanning is limited to Pro and Enterprise. Intruder supports API, Linux, macOS, web, and Windows, and its paid plans have no listed prices.

Alternatives range from free open-source scanners to products with patch deployment, local operation, or broader network discovery. Choose based on whether you need recurring scans and prioritization, detailed inventory, cloud auditing, compliance outputs, or help fixing findings. Consider where scans run, which targets and protocols matter, and whether you need a graphical interface, API, or automation in CI/CD. Check the price and scope of each option against the coverage you rely on in Intruder.
