Shield performs authorized, non-intrusive security checks for its customers. Active checks run only against targets whose owner has verified ownership and authorized them. Scanners do not guess credentials or send exploit payloads. Every request carries this page's address in its User-Agent.
Scanner identification: https://scanner.shield.tensordata.com/scanner

Submitting a hostname or IP address suppresses Shield's scans of it (and, for a hostname, its subdomains) for every customer, immediately. We keep only the target and, if you give one, a reply address.
