JARM vs Censys Threat Hunting: 2026 Comparison
JARM is a free threat hunting tool. Censys Threat Hunting is a commercial threat hunting tool by Censys. Compare features, ratings, integrations, and community reviews side by side to find the best threat hunting 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:
Threat hunters and incident responders investigating malicious infrastructure need JARM because it fingerprints TLS configurations faster than manual banner grabbing, letting you cluster and identify command-and-control servers across thousands of endpoints. The tool has been adopted by major security teams and the open-source community, with over 1,287 GitHub stars reflecting real deployment traction. Skip this if your team lacks personnel trained in interpreting TLS handshake data or if you need automated alerting; JARM is a data collection and analysis primitive, not a managed detection service.
Security teams hunting adversary infrastructure before it hits your perimeter should use Censys Threat Hunting; its correlation engine automatically connects malware C2 servers, phishing domains, and exploit infrastructure across 155+ families in real time. The platform covers three NIST Detect functions (continuous monitoring, adverse event analysis, and risk assessment), but it's detection-forward; you'll do the response work elsewhere. Skip this if you need post-breach forensics or want your threat intel bundled with endpoint detection, since Censys is purpose-built for finding what's out there, not what's already inside.
