Your network, your trust root
Each organization runs its own certificate authority and gets its own network space. Nobody, including Tartan, becomes the authority over who belongs on your network.
Private networks, woven between organizations.
Every organization on Tartan holds its own trust root and its own network space. Sharing with a partner is a scoped, revocable grant, not a VPN login handed over.
Partners get exactly what you grant
Give an IT provider, a vendor or a partner business reach to specific systems, ports and time windows. You see every grant on your network and can revoke any of them.
Names that work everywhere
Every organization gets a free name like acme.tartn.net, with each app switched to internal or public. Phones are full members, with a Tartan app for Android first.
