Best Cloud Infrastructure Entitlement Management (CIEM) Solutions in 2026

Cloud Infrastructure Entitlement Management exists because cloud IAM is the most over-permissioned identity system most organizations have ever operated. AWS, Azure, and GCP each present hundreds of services, thousands of actions, and effectively unbounded permission combinations. CIEM analyzes effective permissions, surfaces over-privilege, and increasingly automates right-sizing. The category does real, measurable work — and it does it on the cloud tenants the platform has been connected to. Anything else is invisible.

What modern CIEM is supposed to deliver

A serious CIEM program in 2026 covers a recognizable set of capabilities:

• Effective permissions analysis across human and non-human cloud identities

• Over-privilege detection and right-sizing recommendations

• Just-in-time access elevation for cloud roles

• Cross-cloud entitlement normalization (AWS, Azure, GCP, OCI)

• Service-account, workload, and federation identity governance

• Compliance reporting aligned to CIS, NIST, PCI, and HIPAA

The CIEM category has matured around several established names — Wiz, Sonrai Security, Saviynt, Microsoft Entra Permissions Management, and Britive — each of which delivers credible CIEM work on the systems they integrate with. The capability is not in question. The scope is.

The hidden flaw every CIEM solution shares

CIEM analyzes the entitlements inside the cloud tenants it's connected to. Cloud tenants outside that connection — whether spun up by engineering teams, paid for on personal cards, or created by SaaS-to-cloud integrations — are invisible by definition.

In a typical mid-market or enterprise environment in 2026, the things that fall outside CIEM coverage tend to look like this:

• Shadow CSP tenants holding production-adjacent workloads

• AI/ML training clouds operated by data teams in personal accounts

• SaaS-vendor-managed cloud accounts that process your data

• Federation paths from your IdP to clouds CIEM has no awareness of

This is why Shadow CSP: the cloud accounts security doesn't know about matters more in 2026 than the CIEM platform itself. Every app, identity, data flow, and AI integration touching your environment is part of the surface — and CIEM can only govern the subset it's been told about.

Shadow AI is the worst case for CIEM

AI workloads spawn permissions at a rate CIEM right-sizing was never designed for. Vector databases need read access to documents. Agents need write access to email and storage. Training jobs need network egress and GPU pools. The right-sizing math is the same; the inventory underneath it has to catch up.

Authoritative guidance has caught up to this reality. The CIS Controls, NIST Cybersecurity Framework 2.0, and CISA SCuBA project all make the same underlying point in different language: you cannot secure, govern, or comply with what you cannot see — and the visible surface in 2026 is materially smaller than the actual one.

For the broader pattern, see the identity supply chain nobody is securing.

What "best" really means in 2026

The candid take: the leading CIEM platforms are real, the capabilities are credible, and the coverage is incomplete by category boundary, not by product failure. Choosing among them is a question of integration depth in the systems you care about most, the workflows that match your team, and budget. What's missing in every selection process is the upstream step — what should the CIEM platform actually be pointed at?

That is the gap Waldo Security closes. Continuous, agentless discovery of every SaaS app, cloud tenant, OAuth grant, AI integration, and unmanaged identity tied to your domain — including the ones that never touch your IdP, your procurement system, or your CIEM catalog. The output is the missing input for CIEM: a real, current map of what should be in scope. For more on how this fits the broader posture program, see Waldo's Cloud Governance.
