Arc4dia Snow Sensor vs autoruns: 2026 Comparison
Arc4dia Snow Sensor is a commercial endpoint detection and response tool by Arc4dia. autoruns 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.
Windows incident responders and SOC analysts hunting for persistence mechanisms will find Autoruns invaluable for its speed; it surfaces every scheduled task, startup folder entry, and registry run key in seconds where manual inspection takes hours. The tool has been a NIST-aligned detection workhorse since Windows XP and requires zero agent deployment or licensing. Skip this if you need real-time monitoring or behavioral analysis of what those startup items actually do once they execute; Autoruns is forensic inventory, not behavioral EDR.
