OSINT

Tenant information

Due to massive automated request attacks, the original anonymous OSINT service had to be permanently closed in September 2025.

The new OSINT tool requiring authentication is available at https://osint.aadinternals.com. To use the tool, you need an Entra ID account with a non-default (.onmicrosoft.com) domain name.
