The answer is more nuanced than most expect. While open source identity management software comes without licensing fees, the total cost of ownership includes implementation complexity, operational overhead, and the expertise required to navigate the intricate world of identity and access management. Understanding these hidden costs is crucial for organizations considering the migration from commercial identity management platforms to open source identity management solutions.
Identity and Access Management isn’t just another IT system—it’s the digital nervous system of your organization. Every user interaction, every application access request, and every compliance audit flows through your IAM infrastructure. This inherent complexity means that the “free” software is often the smallest component of your total investment.
This complexity means that while the open source identity management software is often the smallest component of your total investment. The real value lies not just in avoiding licensing costs, but in gaining the flexibility and control that open source identity management platforms provide over their commercial counterparts.
Open source identity management solutions require deep technical expertise that many organizations lack internally. Unlike commercial solutions with user-friendly interfaces and extensive documentation, open source identity management platforms often demand:
Cost Reality: Hiring IAM specialists with open source identity management expertise can cost €80,000-120,000 annually, and finding qualified candidates often takes 6-12 months.
The “free” software requires continuous investment in:
Organizations often underestimate these ongoing costs, which can range from €60,000-180,000 annually for enterprise deployments.
Open source identity management implementations typically require 50-100% more time than commercial alternatives due to the need for custom configuration and integration work. A typical enterprise deployment involves:
Cost Reality: Project teams of 2-4 people working for 12-24 months can easily cost €200,000-500,000 in internal resources alone.
Despite the implementation complexities, open source identity management solutions offer compelling strategic advantages that can justify the investment:
Commercial IAM vendors have consistently disappointed customers with end-of-life announcements, forced cloud migrations, and licensing changes. Open source identity management solutions provide:
While implementation costs are significant, open source identity management solutions offer long-term cost predictability:
Open source identity management platforms like MidPoint offer unmatched flexibility for complex enterprise requirements:
Recent geopolitical events have highlighted the importance of data sovereignty. Open source identity managementsolutions enable:
Let’s examine a concrete example for a 2,000-employee organization with moderate complexity requirements (50+ applications, regulatory compliance needs, and hybrid cloud infrastructure):
Year 1 Total: €500,000
Annual Operational: €205,000 4-Year Operational Total: €820,000
To remain conservative, we expect a lightweight commercial solution with a license cost under € 4 per identity per month.
Year 1 Total: €855,000
Annual Operational: €250,000 4-Year Operational Total: €1,000,000
The open source identity management solution 5-Year TCO: €1,320,000 Per-User Cost: €132 over 5 years (€26.40 annually)
5-Year Commercial TCO: €1,855,000 Per-User Cost: €185.50 over 5 years (€37.10 annually)
| Cost Category | Open-Source | Commercial | Savings |
|---|---|---|---|
| Year 1 | €500,000 | €855,000 | €355,000 |
| 5-Year Total | €1,320,000 | €1,855,000 | €535,000 |
| Per User (5-Year) | €132 | €185.50 | €53.50 |
Advantages of Open Source Identity Management at This Scale:
The open source identity management solution breaks even in Year 3, with cumulative savings accelerating in Years 4-5. Organizations planning shorter deployments (under 3 years) may find commercial solutions more cost-effective.
The financial advantage of open-source solutions becomes clear over 3-5 years, especially for organizations with stable user bases and complex requirements.
The TCO saving will only grow with the number of identities. Of course, an integrator or vendor will also set prices for the support according to headcount, but there is rarely a direct proportion.
The question isn’t whether open source identity management solutions are “free”—they clearly require significant investment in expertise, implementation, and operations. The real question is whether the strategic advantages justify the costs for your organization.
For many enterprises facing vendor end-of-life situations, the answer is increasingly yes. The combination of cost predictability, vendor independence, and technical flexibility makes open source identity management solutions like MidPoint compelling alternatives to commercial platforms.
However, success requires honest assessment of your organization’s capabilities and realistic budgeting for the full implementation journey. Don’t let the “free” label obscure the reality that building world-class identity management capabilities requires investment, whether in commercial licenses or open-source expertise.
The organizations that succeed with open source identity management are those that treat it as a strategic capability investment, not a cost-cutting exercise. When approached with proper planning, adequate resources, and realistic expectations, open source identity management can deliver both cost savings and superior functionality for years to come.
The bottom line: Open source identity management isn’t free, but it can be invaluable for organizations ready to invest in doing it right.
