Arc4dia Snow Sensor vs Doorman: Side-by-Side Comparison (2026)
Features, pricing, ratings, and pros & cons — compared head-to-head.
Arc4dia Snow Sensor is a commercial endpoint detection and response tool by Arc4dia. Doorman is a free endpoint detection and response tool. Compare features, ratings, integrations, and community reviews side by side to find the best endpoint detection and response fit for your security stack.
CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Mid-market and enterprise teams with constrained endpoint infrastructure will benefit most from Arc4dia Snow Sensor's lightweight agent footprint, which compresses to roughly 500 KB per day per machine while maintaining continuous timeline-based threat telemetry. The tool prioritizes detection and investigation over response orchestration, as evidenced by strong NIST coverage in DE.CM Continuous Monitoring and RS.AN Incident Analysis but no RS.RC Recovery Coordination capability. Skip this if your organization needs automated response actions or deep integration with your existing SIEM; Snow Sensor is built for teams that want raw telemetry fidelity and forensic depth over speed-to-remediation.
Security teams managing osquery at scale will find Doorman's lightweight approach to fleet management valuable when your infrastructure is already built on osquery and you need remote configuration control without the overhead of a commercial EDR platform. The free pricing and 620 GitHub stars reflect active use in lean security shops running osquery across hundreds of nodes. Skip this if you need behavioral threat detection or response automation; Doorman is query management only, not endpoint detection, so it pairs with osquery's detection capabilities rather than replacing them.
