Why bigger is not automatically better and what really matters.

Identity & Access Management – at first, this sounds like large-scale corporate IT, endless project phases and structures that only specialists understand. So it’s no wonder that in many companies the topic is put off until authorizations become confusing, audits mutate into a stress test or, in the worst case, security gaps arise.

IAM is no longer a special topic for IT giants, but a basis for secure and scalable IT, regardless of size. The key question is therefore not whether IAM should be introduced, but what type of solution is right for your own organization. This is exactly what we clarify in this article.

Identity & Access Management ensures that user accounts and access rights are managed centrally, traceably and automatically. This may sound abstract, but it has very concrete effects on everyday working life. IAM means central management of all user identities, automated on, off and role change management, less manual work in administration and significantly fewer errors in authorizations. At the same time, IT security and compliance capability increase considerably.

But IAM is no longer just a question of efficiency, it is a legal necessity. Regulations such as the EU GDPR, the BSI’s IT baseline protection, ISO 27001, NIS-2 or industry-specific specifications such as KRITIS explicitly require documented and traceable management of user identities and access rights. In its IT baseline protection documentation, the German Federal Office for Information Security makes the implementation of identity and authorization management mandatory. Companies must not only document which user IDs and rights profiles have been created, but also regularly check that this documentation is up to date. Without a functioning IAM system, these requirements can hardly be met as IT complexity increases.

The central problem with manual authorization management is that the effort involved grows disproportionately with every new employee, every additional system and every additional application. What still somehow works for small teams quickly turns into chaos from a certain size, with direct consequences for security, efficiency and auditability. By the next audit at the latest, it becomes clear that manual processes no longer meet regulatory requirements.

Not all IAM is the same. The solutions differ considerably in terms of objectives, scope and complexity. Anyone faced with the decision must understand this: There is no universal “best” solution, only the solution that best suits your own situation.

The fundamental difference: process-centric vs. security-driven

Before we get into the details, it is important to understand that enterprise IAM and no-code IAM follow two completely different philosophies. This difference in objectives also explains why the choice is so crucial.

Enterprise IAM: Process automation with accounts & authorizations as a by-product

Enterprise IAM solutions focus on the automation of complex, business-centered processes. The provision of accounts and authorizations tends to be a by-product of the higher-level workflow automation. The long project runtimes are not primarily caused by the technical implementation, but by the fact that existing business processes first have to be formalized and structured. Various specialist departments are often involved in the project in order to create clarity about processes, responsibilities and approval paths. The result is a highly individualized system that precisely maps the company’s specific processes.

No-code IAM: security-driven and user-centered

No-code IAM solutions take a fundamentally different approach. The focus is clearly on the fast and efficient provision of accounts and authorizations to end users. The aim is for employees to be able to work immediately from day one. The burden on IT is relieved by self-service functionalities that enable users to process standard requests independently. The drive is clearly security-centric: the focus is on regulatory compliance, protection against hacker attacks and the implementation of the least privilege principle. Processes are not reinvented, but implemented quickly on the basis of proven best practices.

This different orientation has far-reaching consequences for implementation duration, operating costs and the question of which approach suits your own company.

Enterprise IAM: Maximum flexibility for complex environments

Enterprise IAM suites are primarily aimed at large, international corporations with highly heterogeneous IT landscapes and extensive regulatory requirements. They offer a very wide range of functions, from single sign-on, multi-factor authentication and automated provisioning to governance functions, privileged access management and complex workflow engines.

These systems are designed for maximum integration flexibility. They can theoretically map any scenario, no matter how special, often through customer-specific programming. This makes them powerful, but also complex and resource-intensive. Long project durations, high implementation and operating costs and specialized IAM expertise are the rule.

Many of these solutions consist of several individual products, the full implementation of which is often beyond the time, administrative and financial resources available to medium-sized IT teams. Customer-specific programming sounds attractive at first, but it means considerable customization effort and high maintenance costs.

SME IAM: Focused, pragmatic, fast benefits

Midmarket-oriented no-code IAM solutions take a different approach. They concentrate on a clear focus on core processes, rapid implementation, less integration effort and ease of use for smaller IT teams.

The focus is on automated user and authorization management, standard integrations for common systems such as Active Directory, Microsoft 365 and ERP software as well as rapid productive use with manageable operating costs. The goal is not maximum functionality, but fast, measurable benefits. In most medium-sized companies, we are dealing with 90 percent standardizable processes that can be mapped automatically via IAM.

In concrete terms, the no-code approach means: configuration via a user-friendly interface instead of programming. Ready-made connectors instead of individual scripts. Best-practice processes instead of months of process analysis. The result is a solution that is up and running within a few weeks and immediately delivers tangible added value.

The approach works according to the “bottom-up” principle: the standard scope initially provides the functionalities for the most important and most frequently performed processes. If special requirements are added, the software offers expansion options from the bottom up, not the other way around.

The comparison at a glance

Enterprise IAM suites are aimed at large corporations with complex structures. Implementation takes months to years. Integration is highly individualized, often script-based. The operating costs are high and a dedicated IAM team is often required. The time-to-value occurs late, after long project phases. The complexity is very high.

No-code IAM solutions are aimed at medium-sized organizations. They are productive in just a few weeks. Integration takes place via standardized connectors with configuration options. The operating costs are easily manageable for small IT teams. The benefits can be seen early on through rapid automation. The complexity remains practical and manageable.

Choosing the right IAM solution depends on several factors. If you understand these, you can avoid making expensive mistakes.

Company size and organizational complexity

The decisive factors are the number of users, the number of locations and organizational units, the degree of standardization and regulatory requirements. As a rule of thumb, the more special cases, legacy systems and compliance requirements there are, the more likely it is that an enterprise solution makes sense. The more clearly structured the processes are, the more suitable an SME-oriented IAM solution is.

IT landscape and required integrations

One of the most important questions: Which systems need to be connected and how complex is this? The integration of Active Directory or Microsoft Entra ID is essential, as it is the prerequisite for standardization and automation of frequently required functions. Without an interface between IAM software and these core systems, joiner-mover-leaver processes cannot be adequately mapped.

Cloud capability is just as important. At the latest since Microsoft’s cloud-first approach, the requirements for IAM systems have increased. Modern IAM solutions must support hybrid environments that use both on-premise systems and SaaS applications. They must enable central access management for IT architectures in which different operating systems and different end devices are used.

Typical integrations include Active Directory and Entra ID, Microsoft 365 and Exchange Online, ERP and specialist applications, file servers and various cloud services. Ready-made connectors significantly reduce project duration, costs and operating expenses.

Implementation effort and internal resources

A realistic view of your own capacities is crucial. Do you have internal IAM or DevOps expertise? Or a traditional IT team with limited resources? Overly complex solutions carry the risk of turning into major long-term projects whose potential is never fully exploited. In the end, only a fraction of the planned functionality often remains, which is often accompanied by a security risk, as the focus is usually on modeling the processes and less on security aspects.

Functional scope versus actual demand

Not every organization needs complex workflow engines, deeply integrated privileged access functions or comprehensive governance suites. For many use cases, automated onboarding and offboarding, role-based assignment of rights, recertifications and access requests are sufficient.

User-friendliness is a key factor for success. If users in the IT department as well as in other specialist departments cannot handle the solution, it will not be accepted and the project is doomed to failure. Configuration should be as simple as possible and possible on the user interface, not through programming.

The following also applies to the role concept: roles are important for automation, but they must not get out of hand. If a software does not offer the option of assigning and managing individual authorizations in addition to the fixed roles, you will soon have more roles than users and the concept will have missed its target.

Operating model and compliance requirements

The choice between cloud, on-premise or hybrid depends on data protection and compliance requirements, the existing cloud strategy and internal guidelines.

Regulations such as IT baseline protection, ISO 27001, NIS-2 or the EU GDPR require complete proof of identity and authorization management. The BSI explicitly requires companies to implement identity and authorization management and demands regular reviews of the documentation.

IAM software is a reliable way to ensure that these requirements are met. Modern solutions offer audit-proof documentation, automatic logging of all changes and transparent verification for audits.

Time-to-value and total cost of ownership

License costs, implementation costs, ongoing operation as well as training and consulting costs should be considered in the evaluation. Solutions with a high degree of automation and a low proportion of custom code often perform significantly better over several years than seemingly cheaper but maintenance-intensive alternatives.
