Cloud access has become one of the hardest parts of cloud security to manage well. It is not only about knowing who has access to what. The real problem starts when permissions grow over time, service accounts keep permanent access, old keys are never rotated, and nobody can clearly explain which privileges are actually used.
That is exactly where Cloud Infrastructure Entitlement Management, or CIEM, becomes useful.
In 2026, I would not choose a CIEM tool only because it shows a large permission inventory. A good CIEM platform should help answer practical questions:
Who has excessive access?
Which permissions are unused?
Which human and non-human identities create the biggest blast radius?
Can I move toward least privilege without breaking production?
Can the tool help me remediate, not just report?
After reviewing the tools in this space, these are the five CIEM platforms I would put on my shortlist.
1. Teriam — Best CIEM Software for Continuous Least Privilege and Permission Shrinking
Teriam takes the first place in my list because it focuses on the part of CIEM that matters most in real cloud environments: reducing access, not just visualizing it.
Many cloud security tools are good at showing problems. They can tell you that an IAM role is overprivileged, that a service account has too much access, or that an access key has not been used for months. That visibility is useful, but it is not enough. What I liked about Teriam is that the platform is built around continuous least privilege, rightsizing, and permission shrinking.
The core idea is simple: your cloud should operate based on what is actually used, not what was originally granted.
I would use Teriam when I need to bring structure to a messy multi-cloud IAM environment. For example, if an organization has AWS, Azure, GCP, and Oracle cloud accounts with different IAM models, different owners, and years of accumulated permissions, Teriam helps create a single view of identities and entitlements.
The feature that makes Teriam stand out for me is automated permission shrinking. Instead of forcing the security team to manually review every role and policy, Teriam analyzes actual usage data and generates right-sized least-privilege recommendations. That is especially valuable when cloud teams are afraid of removing permissions because they do not want to break workloads.
I also like that Teriam pays attention to non-human identities. In most cloud environments, the riskiest access is not always tied to a person. It is often connected to service accounts, API keys, tokens, automation users, CI/CD systems, and third-party integrations. These identities can keep permanent access for years, and because they do not behave like normal users, they are easy to ignore.
Teriam’s NHI monitoring is useful for finding those identities, understanding their permissions, and tracking whether they are still active or necessary. I would use it to build an inventory of service accounts and access keys, identify keys that have not been used for more than 90 days, and prepare a safer cleanup plan.
Another practical use case is service account key management. Long-lived keys are still common in legacy integrations and vendor connections, even though they create persistent risk. With Teriam, I would use the visibility into service accounts, keys, usage patterns, and source IPs to understand which keys are actually needed and which ones should be rotated, restricted, or removed.
The remediation code generation is another strong point. When a CIEM tool only gives a recommendation, the work still falls on DevOps or cloud engineering. Teriam’s ability to generate remediation code in formats such as Terraform, CloudFormation, and Bash makes the handoff much smoother. It turns access cleanup into something engineers can review, version, and apply consistently.
What I used Teriam for
I would use Teriam for:
- Building a full inventory of cloud identities and entitlements
- Detecting excessive permissions across cloud environments
- Rightsizing IAM permissions based on actual usage
- Monitoring service accounts, API keys, and tokens
- Identifying unused access and dormant identities
- Preparing evidence for SOC 2, ISO 27001, and CIS-related access governance
- Generating remediation steps and code for cloud teams
Why I ranked Teriam first
I ranked Teriam first because it feels more action-oriented than many traditional CIEM approaches. It is not only about finding overprivileged identities. It is about shrinking permissions continuously and making least privilege something that can actually be maintained as cloud environments change.
For teams that already know they have too much cloud access but struggle to clean it up safely, Teriam is the CIEM platform I would start with.
2. Wiz — Best CIEM Tool for Cloud Security Context and Attack Path Analysis
Wiz is one of the strongest options when CIEM needs to be part of a broader cloud security program. I would not look at Wiz only as a standalone CIEM tool. I would look at it as a cloud security platform where identity risk is connected to vulnerabilities, exposed secrets, data sensitivity, misconfigurations, and attack paths.
That context is the biggest reason to consider Wiz.
A permission may look dangerous on paper, but the real question is what that permission can lead to. Can it reach sensitive data? Can it move laterally to admin access? Is it connected to an exposed workload? Is the identity tied to an inactive user or a risky service account? Wiz is useful because it maps cloud entitlements into a larger security graph.
I would use Wiz when a security team needs to prioritize identity risks by real business impact. For example, if there are thousands of excessive permissions across cloud accounts, Wiz can help separate theoretical problems from risks that create a real attack path.
The CIEM Explorer is also useful for investigations. I would use it to query cloud entitlements by identity, access type, and resource. That makes it easier to answer questions such as “Which identities can access this storage bucket?” or “Which non-human identities have high privileges?”
Wiz also supports non-human identity visibility, which is important in 2026 because machine identities are growing faster than human users in many environments. The platform can help detect risky service accounts, third-party access, excessive permissions, and exposed credentials that attackers could use.
What I used Wiz for
I would use Wiz for:
- Mapping effective permissions across cloud identities and resources
- Investigating identity risks through a graph-based view
- Finding excessive permissions and unused admin access
- Prioritizing identity issues by attack path and cloud context
- Monitoring non-human identities and service accounts
- Connecting CIEM findings with vulnerabilities, secrets, and data risk
Wiz is a strong fit for larger organizations that want CIEM inside a broader CNAPP strategy. If your goal is to combine entitlement management with cloud posture, workload risk, and attack path analysis, Wiz deserves a serious look.
3. Tenable One Cloud Exposure CIEM — Best for Identity Risk Prioritization and Toxic Combinations
Tenable One Cloud Exposure CIEM is another strong choice, especially when the focus is on understanding human and service identities in detail.
What I like about Tenable’s approach is the emphasis on prioritization. In cloud IAM, not every excessive permission is equally urgent. Some permissions are technically broad but isolated. Others become dangerous because they combine with network exposure, sensitive data, privilege escalation paths, or third-party access. Tenable is useful for surfacing those higher-risk combinations.
I would use Tenable when I need to answer executive and operational questions at the same time. Security leaders want to know where the biggest cloud identity risks are. Engineers want to know exactly what needs to be fixed. Compliance teams want to know whether least privilege is being enforced. Tenable’s CIEM capabilities are designed around those questions.
The ability to visualize identities, entitlements, and resources is helpful for investigations. But the more valuable part is automated analysis around excessive permissions, toxic combinations, and remediation workflows. This makes it easier to move from discovery to action.
I would also use Tenable in environments where identity risk needs to be connected with broader exposure management. If the organization already uses Tenable for vulnerability or exposure management, adding CIEM into that same risk model can make prioritization more consistent.
What I used Tenable for
I would use Tenable One Cloud Exposure CIEM for:
- Managing risk across human and service identities
- Finding excessive permissions and toxic combinations
- Prioritizing identity risks based on cloud context
- Investigating suspicious identity behavior
- Supporting least-privilege workflows
- Helping compliance teams understand access exposure
Tenable is a good fit for organizations that want strong identity risk analysis and a structured path from entitlement visibility to remediation.
4. Prisma Cloud CIEM — Best for Teams Already Using Palo Alto Networks Cloud Security
Prisma Cloud CIEM is a strong option for organizations that already use Palo Alto Networks as part of their security stack.
The main advantage here is integration. Prisma Cloud’s CIEM capabilities are built into a broader cloud security platform, so access risk can be reviewed alongside posture management, workload security, infrastructure risks, and compliance issues.
I would use Prisma Cloud CIEM when the goal is to monitor permissions across AWS, Azure, and GCP from one place. The platform helps calculate effective permissions, detect overly permissive access, monitor unused privileges, and generate least-privilege recommendations.
One thing I like about Prisma Cloud is that it gives security teams a practical way to query permissions across users, compute instances, and cloud resources. That matters because cloud IAM is rarely simple. Access can come from direct permissions, inherited roles, groups, identity providers, and resource policies. A CIEM tool needs to simplify that complexity without hiding important details.
Automated remediation is also useful. In many companies, the hardest part of least privilege is not identifying the problem. It is getting cloud teams to make the change safely. Prisma Cloud helps by suggesting corrections and supporting remediation of overly permissive roles.
What I used Prisma Cloud CIEM for
I would use Prisma Cloud CIEM for:
- Reviewing effective permissions across multicloud environments
- Monitoring risky and unused entitlements
- Investigating IAM access paths
- Generating least-privilege recommendations
- Automating remediation of overly permissive roles
- Connecting CIEM with broader cloud security posture management
Prisma Cloud CIEM is a good choice for enterprises that want CIEM as part of a mature CNAPP platform, especially if they already rely on Palo Alto Networks for cloud security operations.
5. Sonrai Cloud Permissions Firewall — Best for Automated Least-Privilege Enforcement
Sonrai is slightly different from the other tools in this list because its Cloud Permissions Firewall is focused heavily on enforcement. That makes it interesting.
Traditional CIEM tools often stop at visibility, reporting, and recommendations. Sonrai’s Cloud Permissions Firewall is built around automatically enforcing least privilege using real cloud activity. It can restrict unused permissions, quarantine dormant identities, and block risky services or regions while trying not to disrupt DevOps workflows.
I would use Sonrai when the organization has already accepted that manual permission cleanup will not scale. In fast-moving cloud environments, permissions change constantly. New roles are created, workloads are deployed, third-party access is granted, and service accounts multiply. A manual review process cannot keep up with that pace.
Sonrai is useful when the team wants to reduce standing access without deleting identities or breaking workloads. The on-demand access model is especially practical: if a permission is blocked because it is not normally used, access can be restored through an approval workflow when someone actually needs it.
That makes Sonrai a strong option for teams that want to move beyond dashboards and start enforcing least privilege more aggressively.
What I used Sonrai for
I would use Sonrai for:
- Restricting unused permissions automatically
- Reducing standing access across AWS, Azure, and GCP
- Quarantining dormant identities
- Blocking risky services, regions, or third-party access
- Supporting on-demand access through approval workflows
- Reducing cloud permission attack surface without slowing DevOps
Sonrai is a good fit for cloud-first teams that want least privilege to become operational, not just theoretical.
How I Would Choose the Right CIEM Tool
The best CIEM software depends on what problem you are trying to solve first.
If I needed continuous permission shrinking, NHI monitoring, service account key visibility, and practical rightsizing recommendations, I would start with Teriam.
If I needed identity risk connected to attack paths, vulnerabilities, secrets, and sensitive data, I would look closely at Wiz.
If I needed strong exposure-based prioritization and toxic combination analysis, Tenable would be high on my list.
If my organization already used Palo Alto Networks and wanted CIEM inside a broader cloud security platform, Prisma Cloud would make sense.
If the priority was automated least-privilege enforcement and reducing standing access quickly, I would evaluate Sonrai.

Final Verdict
For 2026, I would choose CIEM software based on actionability.
Cloud teams do not need another dashboard that says permissions are excessive. They need a tool that shows which access matters, explains why it is risky, and helps reduce it safely.
That is why I put Teriam first. Its focus on continuous least privilege, permission rightsizing, automated permission shrinking, unused access detection, and non-human identity monitoring makes it especially relevant for modern cloud environments.
The best CIEM platform is not the one that produces the longest report. It is the one that helps reduce real cloud access risk before an identity becomes an incident.
