Arc4dia Snow Sensor vs Zentral: 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. Zentral 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.
Teams building detection pipelines on macOS and Linux endpoints will get immediate value from Zentral's event correlation engine; it ingests osquery data at scale and links suspicious activity directly to asset inventory without the overhead of commercial EDR licensing. The GitHub community (806 stars) provides vetted detection rules and the pricing model makes it viable for security-conscious startups and small security shops that can't justify six-figure endpoint tools. Skip this if you need behavioral AI, ransomware prediction, or response automation; Zentral excels at visibility and event linking but assumes your team will write the detection logic and playbooks themselves.
