Identity and Access Management is the discipline of deciding who, or what, gets to access which systems, under what conditions, and proving it after the fact. As the perimeter dissolved into SaaS, cloud, and remote work, identity became the control plane, and it is now the most attacked one: most breaches start with stolen or misused credentials, not malware. The category spans the full lifecycle, from authenticating humans (Access Management, MFA & Passwordless, CIAM) to governing what they can touch (Identity Governance, Privileged Access Management) to the fast-growing problems of machine and cloud identity (Non-Human Identity, Secrets Management, Certificate Lifecycle Management, CIEM) and catching identity attacks in progress (ITDR). It is broad enough that most buyers assemble a stack across several subcategories rather than betting on one platform that claims to do everything.

Common questions about IAM tools, selection guides, pricing, and comparisons.
IAM is the set of tools and processes that control who can reach an organization's systems and data, what they can do once inside, and how that access is proven and revoked. It spans authenticating users with passwords, MFA, SSO, and passkeys, governing permissions over time, securing privileged and machine accounts, and detecting identity-based attacks. With identity now the primary target in most breaches, IAM is foundational to modern security.
Start by identifying which specific identity problem you have, because IAM covers many distinct ones. Workforce login, customer identity, access governance, privileged access, machine and cloud identity, and identity threat detection are separate disciplines. Match your biggest risk and compliance gap to the corresponding subcategory, then judge tools on how deeply they integrate with your existing identity provider, cloud, and HR systems.
IAM is the broad discipline covering all identities and their access. Privileged Access Management is a subcategory focused on high-risk accounts: administrators, root, service accounts, and anyone with elevated permissions. PAM adds credential vaulting, session recording, and just-in-time elevation that general IAM does not. Most organizations need both: IAM for everyone, PAM for the accounts that can do the most damage.
Open-source identity providers handle authentication and SSO well and make a strong foundation, especially for engineering-heavy teams comfortable operating them. Governance, privileged access, identity threat detection, and audit-ready reporting are where commercial platforms pull ahead, in both features and support. Many organizations run open-source for core authentication and buy commercial tools for governance, PAM, and ITDR, where the operational burden and stakes climb.
