Nikto
Classic web scanner: dangerous files, headers and known versions.
Old-school web vulnerability scanner. It fires thousands of requests looking for default files, admin panels, forgotten backups, missing security headers and server versions with known CVEs. It is extremely noisy (any WAF or log will catch it), but in a lab it gives a fast picture of what the server exposes, and its version warnings are often the first thread to pull.
