Shodan on a Mac
Search engine for internet-exposed hosts and services (cloud API) · Security Tools
Shodan continuously scans the public internet and indexes what answers; open ports, service banners, versions, certificates and known vulnerabilities. The point for an administrator is seeing your own servers the way an attacker does: look up your public IP and find the database, admin panel or forgotten dev port you didn't mean to expose. Complements the local firewall and Service Scanner panes, which can only see this Mac's own view. Cloud API with a free tier; store the key below. Look up your own addresses; scanning other people's is their business, not yours.
