CST Verdict

Based on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:

shellfirm

Engineering teams and security-conscious developers will get immediate value from shellfirm because it stops destructive commands at the keyboard before they execute, catching mistakes and supply chain attacks that no post-incident log review can undo. At 884 GitHub stars and free pricing, adoption friction is near zero, making it practical to deploy across dev workstations without procurement cycles. Skip this if your threat model assumes adversaries already have shell access; shellfirm is a human-friction tool, not a containment boundary, and won't stop an attacker who's already inside your terminal.
