Privileged Access Management (PAM) is the software that decides who accesses your most critical systems with elevated rights, and what gets recorded while they do. Two related terms come up around it and are often confused: PIM (Privileged Identity Management) and IAM (Identity and Access Management). The three solve different problems but belong together.

This article answers the three most common questions about them: what privileged access management means, what the difference between PIM and PAM is, and how IAM differs from PAM. Each answer stands on its own, and a comparison table places the terms in context.

What does privileged access management (PAM) mean?

Privileged Access Management (PAM) is a discipline of identity security that controls, monitors and secures the access of privileged accounts to critical systems. Privileged accounts are logins with elevated rights: administrator accounts, service accounts, and the remote access of external service providers.

Such accounts can do almost anything: change configurations, reach sensitive data, delete logs. That is exactly what makes them valuable to attackers. PAM limits this risk through three mechanisms: it grants privileged rights only when needed and only for a limited time (just-in-time), it enforces strong authentication, and it records every privileged session in a traceable way.

The numbers show why this matters: according to the Verizon Data Breach Investigations Report 2025, stolen credentials served as the entry point in 22 percent of breaches and were involved in 32 percent of all breaches. Whoever takes over a privileged account takes over control. PAM is the layer meant to prevent that.

What is PIM and PAM? The difference

PIM (Privileged Identity Management) manages which identities hold privileged rights. PAM (Privileged Access Management) controls and monitors what those identities actually do with their rights. PIM answers the question „Who may hold elevated rights?", PAM answers the question „How is access with those rights controlled and logged?".

In practice the two work together. PIM defines that a specific person may take on the role of „database administrator", and removes that role again once it is no longer needed. PAM makes sure the person authenticates strongly when using it, accesses only the approved systems, and that every session is recorded.

A note on the terminology confusion: Microsoft uses „PIM" in Entra ID for a feature that governs time-bound role activation. In the wider industry, PIM stands for the management of privileged identities. Both readings point to the same core principle: manage the identity and its permissions before access takes place.

What is the difference between IAM and PAM?

IAM (Identity and Access Management) governs the access of all users in an organization. PAM (Privileged Access Management) is the specialized subdiscipline focused on privileged accounts with elevated rights. IAM is the foundation for every employee, PAM is the additional protective layer for the few especially powerful logins.

An image for it: IAM is the locking system for the entire building and gives each employee access to the right rooms. PAM is the secured vault with four-eyes principle, log and camera, where the master keys are kept. Both belong together, and both have a different job.

Concretely this means: IAM manages sign-in, single sign-on and permissions for everyone. PAM is added where accounts have far-reaching rights, and it adds stricter controls such as time-limited approvals, a password vault for shared accounts, and the complete recording of privileged sessions.

IAM, PIM and PAM at a glance

The terms overlap because they build on each other. IAM is the base. PIM and PAM sit on top of it and secure the part that can cause the most damage: the privileged accounts.

Who needs PAM and why

Every organization with administrator accounts, service accounts or external provider access has privileged logins that need to be secured. For operators of critical infrastructure and companies within the scope of NIS-2, controlling privileged access is also a regulatory obligation. NIS-2 (implemented through the BSIG in Germany), ISO 27001 and the BSI minimum standards require that privileged access is restricted, monitored and logged in a demonstrable way.

PAM delivers exactly that evidence: who accessed which system, when, and with which rights, traceable down to the individual session. That turns a compliance requirement into a verifiable state. For a deeper start, see our PAM Beginner's Guide.

Frequently asked questions

What does privileged access management mean?

Privileged Access Management (PAM) is an identity security solution that controls, monitors and secures the access of privileged accounts to critical systems. It detects and prevents unauthorized access through accounts with elevated rights.

What is PIM and PAM?

PIM (Privileged Identity Management) manages and secures the identities of privileged accounts. PAM (Privileged Access Management) manages and secures their access to sensitive resources. Both work together, with IAM forming the foundation and PIM and PAM adding further security layers.

What is the difference between IAM and PAM?

IAM provides comprehensive access control for all users in an organization. PAM focuses on privileged accounts with elevated rights. IAM is the foundation, PAM is the specialized protective layer above it.

Is PAM part of IAM?

Yes. PAM is a specialized subdiscipline of IAM. While IAM manages access for all users, PAM specifically secures the privileged accounts.

Who needs a PAM solution?

Every organization with administrator accounts, service accounts or external provider access. For operators of critical infrastructure and companies within the scope of NIS-2, controlling privileged access is mandatory.

PAM, PIM and IAM belong together but solve different problems. IAM governs access for all users, PIM manages the privileged identities, and PAM controls and logs what actually happens with privileged rights. Anyone who wants to protect their most critical systems needs all three layers, with particular attention to privileged access. It is the target of most successful attacks. To see what a PAM solution looks like in practice, look at VISULOX: developed in Germany, operated on-premises, with tamper-proof recording of every privileged session.
