Network security checker

See what an internet-facing host exposes from the outside: open ports, common misconfigurations, and automated template checks (Nuclei and Nmap). Useful to verify a deployment, review infrastructure you operate, or get a quick check without local scanners. The server runs one scan at a time; results and job status there are not guaranteed to persist after a restart or redeploy. You can leave the page and return; your job id is stored in this browser.

A cooldown applies per resolved IP (including different hostnames that point to the same address). Only use this on systems you are explicitly authorized to test.

Template-based checks use Nuclei — an open-source vulnerability scanner by ProjectDiscovery.
