Cloud Infrastructure Entitlement Management (CIEM) is a security process that enables organizations to manage and govern identities and their entitlements across cloud environments. It helps security teams understand which users, applications or services have access to specific cloud resources, how those permissions were granted and whether that access is appropriate or excessive.
CIEM tools are designed to reduce the risks of excessive or misconfigured permissions by identifying and addressing permission sprawl. This helps ensure that each identity has only the minimum level of access necessary to do their jobs effectively.
Cloud infrastructure entitlements refer to the permissions, roles and access rights assigned to identities (both human and non-human) in cloud environments. These entitlements determine:
Modern cloud environments are dynamic and complex, often spanning multiple providers and involving thousands of human and non-human identities. As these identities gain access to more resources through evolving entitlements, the risk of unauthorized or excessive access grows - often without clear visibility or control.
Without a clear process for managing this complexity, security teams lack visibility into who has access to what and whether that access poses a risk. CIEM is critical because it provides security teams with the visibility and control necessary to prevent identity-related threats.
With CIEM, security teams can:
CIEM is made up of several strategic components that work together to help security teams reduce risk, enforce least privilege and maintain control over cloud access.
Identity and Access Management (IAM): CIEM enhances IAM by providing detailed insights into which users, applications and services have access to specific cloud resources.
Principle of Least Privilege (PoLP): CIEM enforces least privilege by identifying over-permissioned identities and removing unnecessary access.
Access visibility and risk remediation: CIEM continuously monitors cloud environments to catalog all active entitlements, flag risky or unused permissions and provide actionable recommendations for remediation, often with automated guidance.
Identity governance: CIEM supports the full lifecycle management of user and machine identities, including role assignments, access reviews and policy validation.
Security policies: CIEM enables teams to define, enforce and automate custom security policies across multi-cloud environments, such as restricting permissions based on roles, geographic location or time.
Centralized management: CIEM tools provide a unified dashboard to manage entitlements, policies and risks across all cloud platforms.
Compliance: By delivering comprehensive visibility, control and auditing capabilities, CIEM tools help organizations meet regulatory requirements such as GDPR, HIPAA and CCPA.
CIEM works by continuously scanning cloud environments to collect data on resources, identities and their associated permissions and entitlements. It delivers a comprehensive view of cloud access across accounts, platforms and services.
Using this visibility, CIEM identifies potential risks, such as over-permissioned accounts, unused entitlements and misconfigurations that could lead to security breaches. Modern CIEM solutions often incorporate Machine Learning (ML) and behavioral analytics to analyze access patterns and entitlements at scale.
CIEM enforces security policies by automatically revoking unnecessary permissions, blocking unauthorized access and alerting administrators to anomalies or policy violations. It continuously monitors changes in access and behavior to detect threats in real time.
To support governance and compliance, CIEM also generates detailed reports documenting access and entitlement histories.
CIEM helps organizations reduce cloud access risk by offering visibility, control and continuous governance over entitlements. Below are the key security benefits of CIEM:
CIEM enables security teams to enforce the principle of least privilege by identifying over-permissioned identities and automatically removing unnecessary access. This ensures that users, applications and services only have the access required to perform their job responsibilities.
CIEM provides a centralized view of all entitlements across cloud platforms, including how access is assigned (e.g., directly, through roles or group memberships). This helps uncover indirect or inherited access paths, making it easier to understand and manage who has access to which resources and whether that access is still needed.
CIEM continuously scans cloud environments to detect excessive, unused or misaligned permissions that could pose a security risk. It can flag these entitlements based on usage patterns or policy violations and recommend or automate corrective actions, such as downscoping roles or revoking dormant access.
By reducing permission sprawl and tightening access control, CIEM directly shrinks the attack surface across cloud infrastructure. It reduces the likelihood of privilege escalation, lateral movement and unauthorized data access, which are all common attack vectors in cloud breaches.
CIEM simplifies compliance with frameworks like GDPR, HIPAA, SOC 2 and ISO 27001 by generating detailed access logs, entitlement histories and audit-ready reports. It supports ongoing access reviews, monitors policy violations and helps organizations demonstrate consistent access governance to auditors and regulators.
CIEM tools can detect anomalies in access behavior, such as unexpected permission changes, unusual login locations or unauthorized privilege escalation. These insights improve incident response by allowing security teams to quickly investigate and remediate identity-based threats before they lead to data loss or compromise.
Cloud Infrastructure Entitlement Management (CIEM) helps security teams monitor, manage and govern cloud entitlements. CIEM tools provide visibility into who has access to what, detect risky or excessive permissions, enforce least privilege policies and support compliance through continuous monitoring and audit reporting.
Identity and Access Management (IAM) controls who can log in and what resources they are authorized to access. It focuses on authentication and basic authorization.
CIEM, on the other hand, builds on IAM by offering deeper analysis and governance of entitlements in cloud environments. While IAM grants and enforces access, CIEM helps analyze, audit and optimize that access, particularly across complex, multi-cloud environments.
CIEM focuses on managing cloud access and entitlements to ensure permissions are appropriate, aligned with least privilege and continuously monitored. Security Information and Event Management (SIEM) systems collect and analyze security event data across an organization's systems to detect threats, generate alerts and support incident response.
In short, CIEM is about who has access to what and whether that access is secure, while SIEM is about what is happening in your systems and whether it indicates a threat. Although CIEM and SIEM serve different purposes, they can be used together for stronger visibility and threat detection.
