SSO Authentication for a Corporate Extranet in Berlin (2026)

The verdict in three sentences

Adding SSO authentication (SAML or OIDC, connected to Azure AD or Okta) to a corporate extranet costs 8,000 to 20,000 EUR in Berlin in 2026. It removes the management of more than 100 passwords, adds MFA and SCIM provisioning, and eliminates orphan accounts that stay active after an employee leaves. Measurable result: about 60% fewer access tickets and a markedly reduced attack surface.

What SSO costs, and what drives the price

Price depends on the protocol, the target identity provider, the number of roles and the need for automatic provisioning. Here are the 2026 configurations.

SCIM provisioning is the line item that brings the most security value: it creates and, crucially, automatically deactivates accounts when an employee joins or leaves, closing the orphan-account gap.

What SSO concretely changes

Beyond convenience, SSO measurably improves security and operations. Here is the before/after.

SSO also becomes a contractual requirement: many large accounts only open their extranet to partners able to connect via their own identity provider.

Mini case study

Lena, IT director of an industrial group in Berlin, runs an extranet used by 350 employees and 40 external partners. Before SSO, the support team handled about 120 access tickets a month (forgotten passwords, accounts to close). She deploys a standard SSO at 15,000 EUR connected to Azure AD, with MFA and SCIM provisioning. After deployment, access tickets drop to around fifty a month, or -58%, and all accounts of departed employees are deactivated automatically. At 25 EUR handling cost per ticket, support savings reach about 21,000 EUR/year, paying back the project in under a year.

FAQ

SAML or OIDC for a corporate extranet? OIDC is more modern and suited to web and mobile apps; SAML remains very present in large accounts and legacy IdPs. The choice depends on the target identity provider; a good provider supports both.

Is MFA included in SSO? MFA is generally carried by the identity provider (Azure AD, Okta) and enabled via SSO. This is one of the major benefits: strong authentication everywhere without specific development in each application.

What does SCIM provisioning bring? SCIM automatically syncs accounts with the corporate directory: creation on arrival, immediate deactivation on departure. This is what eliminates orphan accounts, the main cause of illegitimate access after a departure.

How long to deploy SSO? Plan 2 to 4 weeks for a standard configuration, more with SCIM and migration of existing accounts. The bulk of the work is integration with the identity provider and role mapping.

Does SSO really reduce support tickets? Yes: by removing multiple passwords and centralising access management, access-related tickets often drop by 50 to 60%. Support savings cover a large share of the project cost in the first year.
