Post-its are not a password manager

LEAN Stability: Enterprise Single Sign-On

Log in.
Done.

15 systems, 27 passwords, no overview. We integrate Enterprise SSO – SAML, OAuth, OIDC – GDPR-compliant and scalable. One login, all systems.

What's it about?

Too many systems, too many passwords, too many security gaps – and an IT department playing helpdesk instead of building infrastructure. Enterprise SSO cleans up.

Your benefit:

  • Onboarding speed ↑
  • User satisfaction ↑
  • Attack surface ↓


Do you know?

What does this bring you?

One login for all systems

Employees authenticate once and have access to everything they need. No five passwords, no password resets, no friction.

Faster onboarding and secure offboarding

New employee: one account, all systems unlocked. Employee leaves: one click, all accesses blocked. Central, traceable, immediate.

Less attack surface

Central password policies, MFA, session management. One security level for all systems instead of five different vulnerabilities.

GDPR-compliant user management

Roles, rights, and accesses centrally documented. Audit-ready, without having to gather Excel lists.

Pilot Phase

Deliver first, then commit. That's what the pilot is for.

  • Duration

    6-10 weeks

  • Assessment

    Which systems need SSO? Which protocols (SAML, OAuth, OIDC) are relevant? What role structure does your organization represent?

  • Derived from this

    IAM selection, configuration, integration plan

Deliverables

  • Selection of an IAM system

    including configuration of 1 realm, 1 client, and up to 3 roles

  • Configuration

    of all necessary token settings, redirect URIs, and claim mappings

  • Filling with test data

    20 fictitious users or up to 100 imported existing users

  • Deployed

    for internal testing purposes

Frequently Asked Questions

FAQ
Do we have to replace our existing Active Directory?

No. Keycloak, Auth0, and others can sit as identity brokers in front of your existing AD or LDAP. Your user database remains, SSO comes on top.

Which IAM system do you recommend?

We prefer to work with Keycloak, Authentik, zitadel (Open Source, self-hosted) for full control. Azure AD if you are already in the Microsoft ecosystem. Auth0 or Okta as a managed solution. We recommend based on your infrastructure.

How long does it take to connect another system?

If the IAM is in place and the target system supports SAML or OIDC: days, not weeks. The groundwork happens in the pilot – after that, each additional connection is incremental.

What about systems that do not support SSO?

There are workarounds for legacy systems without SAML/OIDC support – reverse proxies, header-based authentication, API gateways. We clarify in the assessment what is possible.

Is this GDPR-compliant?

Yes. Central user management makes GDPR easier, not harder: right to information, deletion, access logs – everything in one place. With self-hosting (Keycloak), the data does not leave your infrastructure.

What is the pilot phase?

A clearly defined project with a defined scope – typically 4–12 weeks. You will not receive a concept paper at the end, but a functioning result: real code, tested and deployed. The pilot shows you what we can do before you make a long-term decision.

What happens after the pilot phase?

After the pilot comes the proof: We look together at the results – what worked, what was worthwhile, where are the gaps? Everything measured against defined KPIs, not gut feeling. Based on this, you decide: scale, adjust, or stop. No pressure, no upselling. If the proof convinces, we go into scale – your project grows, your team grows with it, the knowledge stays with you.

Do I have to start with a pilot phase?

No. The pilot is our recommended entry point because it creates clarity for both sides – but it is not a must. If you already know what you need and want to get started right away, we can also join an ongoing project or start directly in a larger scope. We adapt to your pace.

Do you work T&M or fixed price?

Start as a timeboxed pilot in T&M (optionally with cap). No fixed price risk, no lock-in. You see at any time what you are paying for – and can stop at any time. But very few do.
