qsa.sh
SecurityScan your own IP from the terminal in one command
qsa.sh runs a real external security and port scan of the public IP you connect from — no install, no signup, nothing to remember but the URL. A single "curl qsa.sh" spins up naabu for fast port discovery, nmap for service and version detection, and nuclei for known-vulnerability checks, then streams the results live to your terminal in about 25 seconds. It offers three scan depths, from a quick look to a deeper sweep, all driven by the same one-line command, and it only ever reports against the caller's own address, so it stays a true outside-in view of your real attack surface. Free and available worldwide.
Why we built it
Checking what your public IP actually exposes to the internet usually means installing a toolchain, learning three different scanners' flags, and stitching their output together by hand. qsa.sh collapses that into one curl command that runs the same naabu, nmap, and nuclei pipeline from the outside and streams it back live, so anyone can see their external attack surface in seconds without setting anything up.
