Surveillance capitalism. Vendor lock-in. Evil corp stuff.
Just ran Integrity Hash on a 50k file directory. Clean output, zero false positives. Impressive.
Deployed on 3 production servers. The pwss-alerts library integration is solid.
PR submitted for pwss-scanner — improved traversal performance by ~40% on large filesystems.
Custom package request submitted. Waiting to hear back. The selectivity is real.
Full community board launching soon. Join the waitlist →
