Features, pricing, ratings, and pros & cons — compared head-to-head.
ProjectDiscovery Nuclei is a commercial vulnerability assessment tool by ProjectDiscovery. SSTImap is a free penetration testing tool. Compare features, ratings, integrations, and community reviews side by side to find the best vulnerability assessment fit for your security stack.
CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Security teams running high-velocity vulnerability scanning across applications, cloud, and networks will get the most from ProjectDiscovery Nuclei because the 12,000+ template library eliminates weeks of custom detection work and the AI-powered template creation handles zero-days faster than manual rule writing. The hybrid deployment model and real-time automated scanning workflows mean you can scan internal and external attack surfaces without rebuilding your scanning infrastructure. Skip this if your priority is patch management integration or if you need deep correlations across vulnerability findings; Nuclei is a scanner first, not a risk quantification platform.
Penetration testers and AppSec engineers who need to systematically hunt Server-Side Template Injection vulnerabilities will find SSTImap invaluable because it automates what would otherwise be tedious manual testing across multiple template engines and injection points. The 1,173 GitHub stars and free pricing mean it's already battle-tested in real engagements, with no licensing friction to slow adoption across your team. Skip this if you're looking for a commercial platform that bundles SSTI detection with broader web app scanning and incident response workflows; SSTImap is deliberately focused, command-line first, and expects you to own integration into your testing pipeline.
