No Such Department

This server runs security checks for our clients

No Such Department checks the internet-facing systems of companies that hired us: which hosts and ports are open, which web services answer, and whether they have known vulnerabilities.

We check a system only when its owner has asked us to in a signed letter that lists the domains and addresses we may test. The checks are rate limited and leave out denial of service, brute force and other intrusive tests.

Write to abuse@nosuchdepartment.com with the addresses that received it and the time with your time zone. A person reads every message, confirms whether the owner of those addresses authorized the checks, and stops any check they did not authorize.
