HarfangLab Cybersecurity Solutions vs usbdeath: Side-by-Side Comparison (2026)

usbdeath

Organizations with high-security facilities or air-gapped networks running Linux endpoints will find usbdeath valuable for its single, uncompromising job: blocking unauthorized USB access through immediate system shutdown rather than logging and alerting. The tool requires no agent infrastructure or licensing, making it practical for teams that treat USB ports as a genuine attack surface and accept a hard fail-closed posture. Not suited for environments where USB devices are legitimate business tools or where you need forensic visibility into failed access attempts; usbdeath prioritizes prevention through denial over detection and response.
