SANCTUM is the SSH access layer your team stops thinking about. Install one cron line on each server and every engineer, every key, every environment lives in one place. Users converge, access revokes propagate, sudo rotates, and nothing drifts. No daemons to install, no LDAP to babysit. Onboard a new hire in a minute, offboard them in the next. Built for startups and platform teams that have outgrown copy-pasting authorized_keys but aren't ready for a six-figure PAM contract.
