How we build
Identity, devices, secrets, and immutable backups before a product hostname. The brochure is not a product host.
Your side of the wall
On-prem products run on infrastructure you hold. Cloudflare Tunnel is the default edge when there is no public IP.
Identity you already trust
Microsoft 365 / Entra ID and MFA. We do not invent a second directory for a login screen.
White-glove, then walk-out
SST installs on your box, applies the license, and leaves. You get a running system and support — not a git clone.
Licensing
Licensing is issued and renewed from SST mainframe servers. The instance must be able to reach those servers to apply or renew.
