Solution · Access

Single sign-on. One login with MFA for every app.

Every app has its own password, and when someone leaves an account easily stays open. With single sign-on your team signs in once, and you disable one account instead of twenty.

What changes for you

  • Offboarding in one click

    Disable one account and file cloud, VPN, business software and admin consoles are closed. No more forgotten access for former staff.

  • MFA everywhere

    The second factor applies to every connected app, via app or hardware key. A stolen password alone is no longer enough.

  • Self-service password reset

    One password instead of many. Reset by self-service instead of a phone call.

  • Traceable

    Who signed in where and when is logged. That helps with audits, ISO 27001 and NIS2.

Proof of Concept

Try single sign-on before you switch.

We connect two or three of your apps in a test environment. You see what sign-in feels like for your team.

Service or project

We run it for you, or your team takes over.

As a managed service for a fixed monthly price, with updates, backup and monitoring. Or as a project with handover of network plan, runbook and all credentials.

FAQ

Frequently asked questions

What is single sign-on?

Single sign-on means one central login for many apps. The apps trust the sign-in service instead of managing their own passwords.

Do we need this if we have Microsoft 365?

Not necessarily. It pays off with many self-hosted apps or when sign-in should stay in your own infrastructure.

Which technology do you use?

Authentik as identity provider with OpenID Connect, SAML and LDAP, MFA via TOTP or WebAuthn, running in containers on hardened Linux.

Who do you offer this to?

For regulated companies, professions bound by confidentiality and anyone processing sensitive data, and for companies of about 30+ staff with critical systems.
