The verdict in three sentences
Adding SSO and MFA to an enterprise app removes weak passwords, centralises access and meets the security requirements of your enterprise clients. In 2026 in Amsterdam, integration costs 8,000 to 25,000 EUR over 3 to 6 weeks, depending on whether you go with an open-source IdP (Keycloak) or a SaaS (Auth0, Okta, Entra). The real trade-off is not technical but economic: cost per active user can flip the decision over 3 years.
What the integration covers
A serious SSO/MFA integration goes beyond the "Sign in with" button. Here are the 2026 items.
| Item | 2026 cost (EUR) | Timeline |
|---|---|---|
| SSO integration (SAML/OIDC) | 4,000 - 9,000 | 1-2 wk |
| MFA (TOTP, SMS, push) | 2,500 - 6,000 | 1-2 wk |
| SCIM provisioning (auto users) | 3,000 - 7,000 | 1-2 wk |
| Roles and scopes management | 2,000 - 5,000 | 1 wk |
| Logging + GDPR audit | 2,000 - 4,000 | 1 wk |
SCIM (automatic account creation/deactivation from the client directory) is what enterprise IT directors ask for most: it removes manual access management.
Build in-house or SaaS: Auth0/Okta vs Keycloak
The decision rests on monthly active users (MAU) and your tolerance for operations.
| Criterion | SaaS (Auth0/Okta) | Build (Keycloak) |
|---|---|---|
| Setup | 8,000 - 15,000 EUR | 12,000 - 25,000 EUR |
| Recurring cost | ~0.02-0.10 EUR/MAU | Hosting only (~50-200 EUR/mo) |
| At 1,000 MAU | ~250-600 EUR/mo | ~100 EUR/mo |
| At 10,000 MAU | ~1,500-4,000 EUR/mo | ~200 EUR/mo |
| Operations | Outsourced | On you |
| Best for | Fast start, low volumes | High volumes, full control |
Below 2,000 MAU, SaaS is often the most cost-effective and fastest. Beyond that, or for data sovereignty, Keycloak pays back its build cost in 12 to 18 months.
Mini case study
Lucie, COO of a 30-person B2B software vendor in Amsterdam, was losing tenders for lack of the SSO her enterprise prospects required. We integrated OIDC, MFA and SCIM provisioning on Keycloak for 18,000 EUR in 5 weeks, hosting at 120 EUR/month. At 6,000 MAU, the same coverage on Auth0 would cost about 2,400 EUR/month, i.e. 28,800 EUR/year; the build pays back in under 8 months. More importantly, SSO unlocked two tenders worth 90,000 EUR in contracts.

FAQ
SAML or OIDC, what is the difference?
OIDC (based on OAuth 2.0) is modern and suited to web/mobile apps; SAML is still heavily requested by enterprises and legacy directories. A good integration supports both.
Is MFA really essential?
Yes. MFA blocks the vast majority of account takeovers from stolen passwords. It is often a contractual requirement from enterprise clients and insurers.
What does SCIM provisioning bring?
It automatically creates and deactivates accounts from the client directory. An employee leaving cuts access with no manual step, reducing risk and support load.
How long to integrate SSO?
3 to 6 weeks depending on scope (SSO only, or SSO + MFA + SCIM + roles). Simple SSO can ship in 2 weeks.
What GDPR requirements apply to logging?
You must trace logins and access to sensitive data, store these logs securely and time-limited, and be able to prove who accessed what.
