Security model

What Fransys protects by default, what you set yourself, and the airlock between your agent and your infrastructure.

Checked against the console on 23 Oct 2026
  • HTTPS everywhere: every public address has its certificate, generated and renewed on its own, for the fransysapp.com address as well as for your domains.
  • Internal services: a service without access from the internet can only be reached by the services in its project. Databases have no public address until you turn on remote access.
  • Isolated projects: a project’s services can’t see those of other projects on the same cluster; they only communicate through the links you draw.
  • Generated credentials: database passwords are created by Fransys and passed to linked services through their variables. No default passwords.
  • Automatic rollback: a failed deployment is undone, and the previous version stays online.
  • Protected variables: the value is encrypted and can’t be read afterwards, not even by you. It doesn’t appear in the .env export or in plans (it’s masked there).
  • Private registry: the registry password is encrypted, like a protected variable.
  • Cloud accounts: Fransys checks the key with the hosting provider, then never shows it again.
  • Payment: you enter your card or bank account with Stripe; Fransys never sees the numbers.
  • An agent key only grants read access.
  • The agent prepares plans; it has no tool to approve or run them. A person on your team approves each plan in the console.
  • The activity log keeps track of who did what, person or agent key.
  • Removing a key cuts the agent’s access right away.

See What an agent can do.

In an application’s panel, Security and Advanced tabs:

  • Run as non-root, with the Run as user and Run as group;
  • Allow privilege escalation: turn it off if your application doesn’t need it;
  • Drop Linux capabilities;
  • the Seccomp profile;
  • the Kubernetes service account and its rules, if your application talks to the Kubernetes API.
  • No secrets in the code or in the image: use protected variables.
  • Remote access to a database opened only for as long as you need it.
  • Two-factor authentication on your account. See Account security.
  • Named agent keys, one per agent or per person, removed when no longer used.
