Cloud infrastructure entitlement management (CIEM) is a category of security tools that shows who and what can access resources in cloud infrastructure platforms such as AWS, Microsoft Azure and Google Cloud, and helps reduce those permissions to what is actually needed. It covers human users and, just as importantly, machine identities such as service accounts, roles, functions and automation. The goal is least privilege in the cloud: every identity able to do what its job requires, and no more.
At a glance
- CIEM focuses on cloud permissions, called entitlements, for both people and machine identities.
- It compares what each identity is allowed to do with what it actually does, and recommends removing unused access.
- It typically covers one or more public cloud platforms and is often sold as part of a cloud-native application protection platform (CNAPP).
- It helps find risky combinations, such as an identity that can escalate its own privileges or reach sensitive data.
- Changes usually need review before they are applied, since removing permissions can break applications.
What problem it solves
Cloud platforms offer fine-grained permissions, but in practice they are granted broadly. Developers get administrator rights to move fast, applications receive wide roles because narrowing them takes time, and access keys for departed staff or retired projects stay active. Across several accounts and clouds, the result is thousands of identities with permissions nobody has reviewed. Attackers who steal one credential, from a leaked key or a compromised workload, can use those excess permissions to move further and reach data.
Non-human identities make this harder. Service accounts and roles used by applications often outnumber people and rarely go through the access reviews that human accounts do. CIEM gives security and cloud teams a clear map of who can do what, highlights the riskiest excess, and makes right-sizing practical at cloud scale.
How it works
Connection. The tool connects to cloud accounts, usually with read-only access to identity configuration and activity logs, and often to identity providers that federate users into the cloud.
Entitlement mapping. It builds a picture of every identity, every policy and role attached to it, and the effective permissions that result, including inherited and cross-account access.
Usage analysis. By comparing granted permissions with activity logs over time, it shows which permissions are used and which are not.
Risk detection. It flags issues such as unused administrator rights, inactive identities, old access keys, public or cross-account exposure, and paths that would let an identity grant itself more privileges.
Remediation. It recommends tighter policies and, in many products, can generate them as policy documents or infrastructure-as-code changes, open tickets, or apply changes after approval. Some support time-limited access for tasks that need elevated rights.
When it matters for buyers
- When cloud use spreads across many accounts or clouds. Manual permission review stops scaling quickly.
- When an audit asks about least privilege. CIEM reports can show what access exists and what was removed.
- When consolidating cloud security tools. CIEM is a common module in CNAPP platforms, so compare it with standalone options. See our public cloud overview.
- After an incident involving a leaked key or credential. The damage depends on what that identity was allowed to do.
- When extending privileged access controls to the cloud. Cloud administrator rights are privileged access and need the same scrutiny.
Questions to ask vendors
- Which cloud platforms, and which identity providers, do you support?
- How do you calculate effective permissions, including cross-account access and inherited roles?
- How long a history of activity do you need before recommendations are reliable?
- Can you generate least-privilege policies or infrastructure-as-code changes, and can we review them first?
- Do you support just-in-time or time-limited elevated access?
- Is CIEM sold separately or only as part of a broader platform, and how is it priced?
- How does it work with our existing identity governance and privileged access tools?
How it differs from IAM and PAM
Identity and access management (IAM) is the broad discipline and set of tools for managing identities and granting access, including the native IAM services inside each cloud. CIEM sits on top of cloud IAM and analyzes the permissions it has granted, finding and removing excess. Privileged access management (PAM) controls and records how people use high-risk accounts, such as administrator credentials, through vaulting, approval and session recording. CIEM is narrower in platform, focused on cloud infrastructure, but broader in identity type, covering both human and machine permissions there. Identity governance and administration (IGA) runs access reviews and joiner-mover-leaver processes, usually for people across business applications. Many organizations use all of these together.
