CST VerdictBased on our analysis of available product data, here is our conclusion:
Security teams handling high-volume document intake from external sources should start with DocBleach because it strips malicious macros and embedded objects from Office files without requiring endpoint agents or cloud uploads. The tool is free and open source on GitHub with 156 stars, making it trivial to pilot in air-gapped or compliance-sensitive environments. Skip it if you need post-incident file recovery or threat intelligence; DocBleach disarms threats through removal, not preservation.
Security teams protecting air-gapped or highly restricted Linux environments will find Silk Guardian's kernel-level USB kill-switch valuable where standard EDR fails to block physical exfiltration paths. The tool is free, open-source with 720 GitHub stars, and deploys as a lightweight kernel module that operates transparently without requiring endpoint agents or network connectivity. This is not for organizations seeking layered endpoint detection; Silk Guardian does one thing and doesn't attempt to cover Detect or Respond functions, so it works best as a perimeter hardening control alongside existing EDR rather than as a replacement.
