Benchmark

Open-source vulnerability management benchmark

A vendor-neutral comparison of open-source vulnerability management and scanning tools, scored against the risk-assessment and patching controls that NIS2, DORA and ISO 27001 expect from essential entities.

What we compare

Open-source vulnerability scanners, side by side

Comparison subjects

The benchmark evaluates well-known options including OpenVAS / Greenbone and other open-source vulnerability management platforms. Where teams research a Nessus vs OpenVAS or commercial vulnerability scanner decision, we map where free tooling is sufficient and where a paid scanner earns its keep. We also cover free dark web scan services as an adjacent signal.

Coverage and accuracy

How each open source vulnerability scanner discovers assets, detects flaws and controls false positives.

Network scanning

Depth of network vulnerability scanner coverage, authenticated scans and asset discovery across your estate.

Workflow and remediation

Ticketing, prioritisation and reporting โ€” how a free vulnerability scanner turns findings into fixed vulnerabilities.

Why vulnerability management matters for compliance

Risk-management measures

NIS2 Article 21 expects vulnerability handling and disclosure as a baseline security measure.

Evidence for auditors

A managed scanning cadence produces the evidence ISO 27001 and DORA reviewers ask to see.
