Control AI access

Last validated: Apr 9, 2026

Aperture by Tailscaleis currently in alpha.

Aperture uses Tailscale's identity layer to automatically authenticate users. Control which users can reach the Aperture instance through tailnet access controls, then use Aperture grants to define which models each user or group can access. Aperture is deny-by-default: without grants, users can connect but cannot access any models.

For background on how identity and grants work, refer to How Aperture works.
