CohortClass of 2026What it is
qsa.sh lets you perform an on‑demand external security audit of your server's public IP directly from the command line. It enumerates open ports, identifies services, and checks for known CVEs in seconds, making it ideal for developers and sysadmins who need fast visibility without signing up. Free basic scans are available, with paid tiers for deeper, asynchronous analysis.
