Cloud infrastructure entitlement management (CIEM) is a cloud security solution that helps organizations enforce least privilege across multicloud environments. It discovers and rightsizes excessive permissions and continuously monitors cloud identities—including nonhuman identities—for access risk.
CIEM is a specialized branch of identity and access management (IAM) that focuses on addressing cloud-access risks that traditional IAM platforms were not originally designed to analyze. CIEM tools discover cloud permissions across major cloud providers—such as Amazon Web Services (AWS), Microsoft Azure, IBM and Google Cloud—and reduce excessive privileges, a process known as “rightsizing.”
CIEM is a key tool for operationalizing least privilege access for cloud environments, where permissions are often too granular, too dynamic and too numerous to manage manually.
AWS alone defines tens of thousands of IAM actions, individual operations such as reading a file, launching a server or deleting a database. Each one must be explicitly allowed or denied for every identity. Across thousands of identities, tracking it all by hand becomes impossible. CIEM does it automatically, mapping every action an identity can take and flagging the ones it never uses.
Rather than standing as its own tool, CIEM is often a feature of broader cloud-native application protection platforms (CNAPPs) that bundle multiple cloud security tools into one suite. CIEM works much like the other tools inside a CNAPP: all of them connect scattered pieces of cloud data to find risks a single tool would miss.

CIEM matters because cloud identities often hold far more access than they need, and that excess can turn a stolen credential into a major data breach. By continuously discovering and rightsizing excessive permissions, CIEM limits how far an attacker can move and shrinks the blast radius of any compromise.
Modern multicloud environments are home to thousands of cloud identities: people, workloads, applications, service accounts and AI agents working across private and public clouds. And each of these identities has some set of cloud permissions that allow them to do things like read databases, write to storage or call another service.
Much of cloud security comes down to making sure that no identity misuses its permissions or holds more than it needs. Unfortunately, most do.
In an analysis of more than 680,000 identities across cloud accounts, Palo Alto Networks’ Unit 42 found that 99% of cloud users, roles and services had excessive permissions. Those permissions can create major security risks, expanding what a single stolen credential can reach.
According to the IBM Cost of a Data Breach 2025, breaches that begin with compromised credentials cost an average of USD 4.67 million and take about 246 days to contain.
The IBM X-Force Threat Intelligence Index 2026 found that stolen or misused credentials accounted for 32% of cyberattacks. Attackers increasingly target the cloud ecosystem—identities, integrations and access—rather than the underlying infrastructure.
This cloud identity attack surface is exactly what CIEM addresses. While CIEM can’t stop credential theft or patch software vulnerabilities, it can narrow what each identity is allowed to do. CIEM helps enforce the principle of least privilege (PoLP), which holds that every identity should have only the access it needs to do its job, no more and no less. PoLP makes it so that each stolen credential gives threat actors less to exploit. In this way, it limits lateral movement and unauthorized access, reinforcing a broader zero trust security approach.
CIEM has also become urgent because of the sheer number of identities that need managing in the cloud. Machine identities and nonhuman identities (NHIs)—service accounts, workload identities, bots and AI agents—now significantly outnumber human ones. Estimates vary, but most put the ratio at anywhere from 45:1 to more than 90:1.
Collectively, NHIs represent a massive attack surface. Each one is a potential vulnerability if its permissions aren’t carefully scoped—and they rarely are. According to OWASP, overprivileging is one of the top 10 risks associated with nonhuman identities. Because they’re integral to core workflows such as the DevOps lifecycle and system backups, NHIs often have privileged access to sensitive data. And in the interest of making these processes “just work,” organizations often give NHIs higher privileges than they need.
NHIs are especially hard to govern in cloud and multicloud environments because they’re created and destroyed constantly. They’re spun up by automated workflows, cloned across accounts and often forgotten—far faster than human identities and far faster than periodic access reviews can track.
By enforcing PoLP, CIEM solutions help address these risks, granting organizations more visibility into which identities exist and helping to ensure that each operates with only the access it needs.
AI agents pose a new class of identity challenges. They’re often spun up quickly with broad permissions. They can take on new tasks and delegate access to other agents—often faster than anyone can review what they’re allowed to do. CIEM helps hold agents to the same standard as any other identity, granularly scoping their access and flagging when they drift.
Most enterprises run on more than one cloud, and each major provider has its own IAM model. AWS uses IAM policies attached to users, groups, roles and resources. Azure uses role-based access control (RBAC) combined with conditional access. Google Cloud uses IAM roles and organization policies. IBM Cloud IAM implementations often use a combination of resource groups and access groups.
The same identity can end up with different permissions in each different cloud. And no single provider’s console shows what an identity can do across all of them. Most legacy IAM products were built for human users in a standardized network. They can handle provisioning, authentication and access controls in a well-defined, consistent IT environment, but they were not designed to reconcile the disparate IAM systems of disparate cloud providers.
CIEM helps address this gap by enumerating each identity’s cloud permissions across every cloud provider. CIEM tools compare granted permissions to used permissions to determine which are actually necessary. They can also flag the wildcard scopes and inherited policies that drive many cloud breaches.
Ultimately, CIEM gives security teams a single view of identities’ permissions across every cloud, enabling them to catch and correct excessive access issues that traditional IAM tools can’t see.
CIEM solutions continuously assess and reassess cloud access through constant monitoring instead of periodic snapshots. Continuous monitoring matters because cloud identities are created, changed and destroyed constantly. A one-time audit would go stale almost immediately.
Most CIEM platforms follow the same four-stage automation process, effectively rerunning it on a loop as the environment changes.
The platform typically connects to cloud providers through application programming interfaces (APIs) with minimally privileged access. It continuously enumerates every identity in each provider’s cloud—human user, service account, workload identity and AI agent—as they’re created and destroyed. It also collects the roles, groups and security policies attached to these identities and the resource-based policies attached to cloud resources.
From that inventory, CIEM builds a permissions graph: which identities can reach which resources and what they can do with them. It compares granted permissions against observed usage drawn from logs such as AWS CloudTrail and Google Cloud Audit Logs, typically over a 30- to 90-day window. For short-lived identities that never last that long, it evaluates the permissions they were granted against what they actually did while active.
The output is a map of effective permissions and how much of each cloud identity’s access is actually being used, scored by risk. It breaks down how broad each identity’s access is, how much sensitive data it can reach and how much of it goes unused. This information helps teams determine which identities to focus on first.
If there’s a gap between granted permissions and used permissions, CIEM generates remediation recommendations. These recommendations can include dropping permissions that have never been used and proposing just-in-time provisioning for one-off privileged actions. CIEMs also recommend replacing wildcard scopes with specific resources—that is, swapping broad “access everything” permissions for ones that name only the resources an identity actually uses.
For instance, consider an engineer who created a CI/CD service account with a wildcard policy and never revisited it. If 90 days of activity show that the role only ever reads and writes objects to a single bucket prefix, CIEM can produce a scoped policy covering that prefix and dropping the rest.
Some platforms apply approved recommendations automatically. Others produce policy-as-code snippets that security teams can review and merge through the same pull-request workflow used application code. Policy as code allows access changes to move through version control and peer review rather than being made by hand in a console.
As identities appear, change and disappear, CIEM keeps rescanning for permission drift and flags anomalous cloud access, such as an identity doing things it has never done before. It also alerts on toxic combinations, such as an identity that can both write to production and delete audit logs.
Many platforms also layer machine learning and behavior analytics into this stage to support real-time threat detection. These tools establish a baseline for each identity’s normal activity, then flag any deviations from it. Behavioral analytics allow CIEM to not only map permissions but actively detect access issues as they happen.
Many CIEM tools place the full inventory of identities and permissions across every connected cloud into a dashboard. Dashboards allow security teams to see and search each identity’s effective permission: what it can actually do when every role, group and policy is combined—not just what its base policy says.
For instance, say that a security analyst wants to know whether a particular service account can reach a storage bucket holding sensitive data across three AWS accounts. They can answer that question with a single dashboard query instead of three separate console sessions.
The cumulative effect of rightsizing thousands of cloud identities is a measurably smaller attack surface and meaningful optimization of access permissions across the cloud estate. Because CIEM ranks identities by risk, teams can strip the most dangerous permissions first.
Every wildcard scope stripped from a policy is one less path that an attacker can take with a stolen credential. The fewer excessive privileges that an identity carries, the smaller the blast radius of any single compromise.
Manual access reviews can’t scale to multicloud environments where the entitlements for hundreds of thousands of identities can change every week.
CIEM streamlines the work by automating discovery, rightsizing and monitoring, and by giving security teams the workflows to push policy changes the same way developers push code.
Many CIEM platforms can baseline what normal access looks like for each identity, then flag any departure from that baseline in real time. Behavior analytics can also extend CIEM from purely preventive controls into detective ones, catching credential abuse closer to real time.
For instance, if a service account that has only ever read from one database suddenly starts enumerating storage buckets across the cloud, CIEM can flag the deviation as it happens. The potential compromise is caught long before a quarterly access review would catch it.
Least privilege access control is a baseline requirement in many major security frameworks, including voluntary frameworks such as the NIST Cybersecurity Framework (CSF) and mandatory regulations such as the General Data Protection Regulation (GDPR).
CIEM tools offer organizations an effective way to bring cloud environments in line with these compliance requirements.
CIEM solutions sit in a stack of related cloud security and identity security solutions.
While the boundaries between them have always beent fuzzy, the current trend is toward consolidation. Security teams often want fewer, more integrated tools, and CIEM’s benefits tend to compound when it works alongside the other controls in a broader cloud security strategy rather than in isolation.
IAM is the broad cybersecurity discipline of provisioning, authenticating and authorizing identities across all systems.
CIEM is a specialized subset focused on cloud entitlements. Traditional IAM asks, “Who is this user, and should they be allowed to log in?” CIEM asks, “What can this identity actually do inside our cloud environments, and is that more than it needs?” Most enterprises run both.
Identity governance and administration (IGA) tools manage the identity lifecycle, including provisioning, deprovisioning and access certification, primarily for human users accessing enterprise applications.
IGA answers governance questions: Should this person have this access, and can we prove that we reviewed it? CIEM answers operational questions about cloud entitlements: Given the access an identity already has, what can it do and is it scoped correctly?
Privileged access management (PAM) focuses on a specific population: privileged accounts such as administrators, root users and service accounts with elevated permissions. PAM stores credentials in a secure vault, brokers just-in-time access and monitors privileged sessions.
CIEM is broader, covering every identity in cloud environments, privileged or not, and ranking them by access risk. PAM only operates on accounts designated as privileged by security teams.
The two overlap when CIEM identifies an overpermissioned service account that PAM can then bring under control. For instance, CIEM might surface a service account with standing write access to a production database that it uses only during quarterly maintenance. PAM can then store those credentials securely and grant them just-in-time, only for the window when the maintenance runs.
Cloud security posture management (CSPM) catches misconfigurations in cloud infrastructure: a publicly accessible storage bucket, an open port, a database with encryption disabled. CIEM catches misconfigurations in cloud identities: an overpermissioned role, a dormant service account, a toxic combination of permissions on a single identity. CSPM protects the structure of the cloud; CIEM protects who can interact with that structure and how.
CNAPP is the umbrella category that bundles CSPM, CIEM, cloud workload protection, vulnerability management and threat detection into a single platform. Its defining feature is correlation. Instead of treating an overpermissioned role, an unpatched workload and a public-facing endpoint as three separate findings, a CNAPP connects them into a single attack path.
Gartner, which originally defined the CNAPP category, has documented a broader shift toward consolidation, with capabilities like CIEM increasingly delivered as a module within these platforms rather than as standalone purchases.
