Cedar

About Cedar

Cedar is a language for defining permissions as policies, along with a specification for evaluating those policies. It is used to define who is authorized to do what within an application. Cedar is open source. The language supports common authorization models such as RBAC and ABAC. Its policy structure is designed to be indexed for quick retrieval and real-time evaluation. Cedar is designed for analysis using Automated Reasoning.

Products

  • Cedar: A language and specification for defining and evaluating authorization policies.
  • Amazon Verified Permissions: A fully managed AWS service for storing and evaluating Cedar policies.

Used for

  • Defining who is authorized to do what within an application.
  • Supporting authorization use cases for RBAC and ABAC models.
  • Evaluating policies in real time with bounded latency.
  • Deploying access control across multiple services with minimal code repetition.

How to evaluate Cloud Security & CSPM

This is how the CIOPages Research Team evaluates this category. It is not an assessment of Cedar. It comes from our Cloud Security Posture Management (CSPM) buyer guide.

25%
Risk Prioritization & Attack-Path Analysis
Context graph that correlates misconfiguration, internet reachability, identity/permissions, vulnerabilities, secrets, and data sensitivity into ranked attack paths to crown-jewel assets; toxic-combination detection; quality of the “fix these 10” output versus raw finding volume; false-positive rate in your own accounts
20%
Coverage Model: Agentless Breadth vs. Runtime Depth
Agentless snapshot/API scanning for fast 100%-estate visibility versus agent/eBPF runtime for in-production threat detection (CDR); container, serverless, and Kubernetes (KSPM) coverage; how the two models combine without double-counting; performance impact and deployment friction
20%
Multi-Cloud & Platform Consolidation (CNAPP)
Depth and parity across AWS, Azure, GCP, OCI, and Kubernetes from one console; how many of CSPM, CIEM, CWPP, DSPM, KSPM, and code/IaC security are genuinely unified on one data model versus bolted-on acquisitions; single policy and one risk score across domains
15%
Identity & Entitlements (CIEM)
Effective-permission analysis across human and machine identities, cross-account and federated role mapping, detection of unused and over-privileged entitlements, least-privilege right-sizing recommendations, and privilege escalation / lateral-movement path discovery
10%
Remediation, Automation & Developer Workflow
Guided and auto-remediation, IaC and pull-request fixes (shift-left to code), guardrails that prevent drift, ticketing/SOAR integration, ownership routing to the right team, and API/Terraform coverage for security-as-code
10%
Compliance, Reporting & SOC Integration
Out-of-the-box frameworks (CIS, PCI DSS, HIPAA, SOC 2, FedRAMP, NIST) with custom policy authoring, audit-ready evidence and drift history, RBAC/SSO on the console, and clean export of correlated cloud risk into the SIEM/SOC rather than a siloed dashboard
