CST VerdictBased on our analysis of available product data, here is our conclusion:
USB Keystroke Injection Protection
Linux security teams managing physical access risks on shared workstations or kiosk deployments should use USB Keystroke Injection Protection because it blocks BadUSB attacks that traditional endpoint agents ignore. The tool runs as a lightweight daemon with 549 GitHub stars and addresses a gap in NIST Identify controls that most EDR platforms don't cover; it assumes devices are already on the network and trusted. This isn't for Windows or macOS environments, and it won't help if your threat model centers on software-based credential theft or lateral movement after initial compromise.
