PortWarden provides scheduled external exposure monitoring for small businesses, startups, technical founders, and lean IT teams. Add a domain or public IP, and PortWarden continuously scans for open ports, exposed services, configuration drift, and other internet-facing risks. Teams receive change alerts, plain-language reports with evidence, and guided remediation support that helps prioritize fixes and validate results after changes are made. On-demand advanced testing is available when deeper validation is needed. Free monitoring is included for up to three endpoints.
