What is CIEM? Cloud infrastructure entitlement management explained
What does a CIEM tool do?
Cloud permissions are layered: users, groups, roles, service accounts, policies attached at several levels, and trust relationships that let one identity act as another. CIEM reads all of it through cloud APIs and computes the effective permissions each identity has.
It then compares what an identity can do with what it has done, so unused permissions can be removed, and flags risky combinations such as a role that can both create users and attach policies.
Machine identities (roles used by functions, pipelines and workloads) usually outnumber people, which is why the category exists separately from workforce identity tools.
When do you need CIEM?
- You run two or more clouds, each with its own permission model.
- Serverless functions and pipelines create many roles nobody reviews.
- An audit asks who can reach a given data store and you cannot answer quickly.
- You want least-privilege changes suggested from actual usage.
When is CIEM not enough?
CIEM covers cloud infrastructure permissions. It does not manage your workforce directory, single sign-on or joiner-mover-leaver processes; those belong to identity governance tools. And it tells you what an identity could do, not whether an attacker is using it right now, which is detection and response.
Which finder answers point to CIEM?
- +2 if you pick two or more public clouds
- +1 if your team is more than ten people with a security operations team
- +1 if you protect serverless functions

Not in our sources is not a no. Ask the vendor, and send us a public source if one exists.
What should you ask a CIEM vendor?
- Does the product compute effective permissions across all the clouds you run?
- Does it compare granted permissions with permissions actually used?
- Is CIEM a named module in the quote, or part of a broader graph?
- Can it propose a least-privilege policy you can apply?
Frequently asked questions
Is CIEM part of IAM?
It works on the same permissions but from the security side: it audits and reduces cloud infrastructure entitlements rather than issuing identities to people.
Which vendors list CIEM?
The table above shows it from each vendor's pages.
Why does the finder add CIEM points for multi-cloud?
Each cloud has its own permission model, and the chance of an over-permissioned role that nobody reviews grows with each one you add.
