# PlainID alternatives

Search for PlainID alternatives and you get lists of 10, 48 or 60 products. Most of them are identity providers, access governance tools and privileged access products. 

Those are good at their jobs, but none of them makes the fine-grained decision PlainID makes at runtime, on whether this person, service or agent may do this action on this resource.

This guide is for identity, security and engineering leaders who already run PlainID or have it on a shortlist. It covers what PlainID does and costs, why teams look elsewhere, which kinds of tools can actually replace it, what to ask any replacement, and how to switch without a big bang cutover.

## What PlainID does and who uses it

PlainID is a policy-based access control ([PBAC](https://www.cerbos.dev/features-benefits-and-use-cases/pbac)) platform, founded in 2014 and based in Tel Aviv and New York. It sells to large, regulated enterprises, mostly in financial services, insurance and healthcare. In October 2026 it relaunched as a "runtime authorization" platform, with a focus on AI agents.

The platform has five main parts.

* A policy administration console, where business and security users author policy visually, with Structured Rego for policy as code.  
* Policy information points, which pull identity and resource attributes from other systems.  
* Decision points, run by PlainID or by you.  
* Prebuilt connectors called Authorizers, for application stacks, API gateways, data platforms and AI frameworks.  
* Audit reporting.

It also discovers agents, tools and data sources, and orchestrates the native authorization of platforms such as Snowflake.

**That is the baseline any PlainID alternative has to meet.** Centralize authorization policy, decide at runtime with real context, enforce close to the resource, and prove what happened.

## What PlainID costs and how it is sold

PlainID does not publish pricing and has no free tier. Evaluation starts with a demo request and pricing is set by quote, so most teams only learn the cost well into a sales cycle.

The license is only part of the cost. One independent review describes PlainID as "a heavyweight enterprise platform" and says "the deployment, modeling, and rollout effort is significant" ([Start with Identity](https://startwithidentity.com/vendors/authorization/plainid/), June 2026). Large consultancies hire specialist PlainID engineers, which tells you how much of a typical rollout is services work.

Cerbos, for comparison, publishes its [pricing](https://www.cerbos.dev/pricing). It has a \$0 proof of concept tier, Development from \$25 a month, Production from \$933 a month and custom Enterprise contracts, all based on monthly active principals.

## Why teams look for a PlainID alternative

These are the reasons enterprises that evaluated PlainID gave us, and the ones independent reviews describe.

* **Policy authoring at scale.** A visual console suits a few administrators and a few hundred rules. Programs heading toward thousands of policies want rules they can review, test and version like code. Teams that evaluated PlainID told us its policy authoring and curation fell short of what they needed. Its Structured Rego answer is a Rego dialect tied to PlainID's own metadata.  
* **Where policy is managed.** In PlainID's SaaS and hybrid models, which PlainID describes as the most common, the policy administration layer runs in PlainID's cloud. Regulated teams increasingly want the control plane in their own infrastructure.  
* **Rollout effort.** A heavyweight platform takes a heavyweight rollout, with modeling, configuration and services before the first application is governed.  
* **Pricing you cannot see.** Quote-only pricing makes it hard to build a business case or compare options early.  
* **Reach without more connectors.** Covering applications, gateways, data platforms and now AI agents means deploying and maintaining an Authorizer for each one.

## Who needs a PlainID alternative, and how urgently

If PlainID governs a stable set of applications and your next renewal is a year away, nothing has to change tomorrow. Use the time to prove an alternative on one service.

The pressure is real if any of these apply.

* A renewal is coming up.  
* You are starting a program to consolidate entitlements across many applications.  
* Your security team has been asked to govern AI agents and needs policy it can review and evidence it can show.  
* Your architecture review has ruled out a hosted control plane.

## What to look for in a PlainID alternative

These are the questions enterprises score authorization platforms on, taken from the evaluations we have seen. Ask them of any replacement, including us \- Cerbos.

1. **How is policy written, reviewed and tested?** Can a security reviewer read a rule? Do changes go through code review, with tests that block a bad policy? Does it work at thousands of policies, not just hundreds?  
2. **Where do decisions run, and where does the control plane run?** Can both run in your infrastructure, including on-premise and air-gapped? What happens to decisions if the vendor's service is down?  
3. **How far does one policy set reach?** Applications, API gateways, service meshes, data platforms, legacy applications you cannot change, and AI agents, without a separate connector to maintain for each.  
4. **What evidence does each decision leave?** Can you show the policy that was in effect at the time, the inputs, the outcome and who changed the policy?  
5. **How does it get context?** Can it fetch current identity and resource data at decision time, so a person who changed role an hour ago is evaluated with today's role?  
6. **Is it built on open standards?** Does it support [AuthZEN](https://www.cerbos.dev/authzen), and can the policies move if you ever leave?  
7. **What does it cost, and how long until the first production policy?** Public pricing, setup cost, and the services needed to get there.

## The main types of PlainID alternative

The products on PlainID alternatives lists fall into seven groups. Only some of them replace what PlainID does.

**Identity providers and access management**, such as Okta, Microsoft Entra ID and JumpCloud, top most lists. They authenticate users, run single sign-on and assign coarse roles and groups. They decide who gets in, not what a person can do to a specific record once inside, so they sit in front of an authorization platform rather than replacing one.

**Identity governance and access reviews** provision roles, run certifications and report on who holds which entitlement. They work at admin time, not at the moment of each request, and the fine-grained permissions inside applications stay outside their reach.

**Privileged and just-in-time access tools** control access to infrastructure, servers and admin consoles. They govern administrators and engineers, not the business decisions inside your applications.

**Enterprise [ABAC](https://www.cerbos.dev/features-benefits-and-use-cases/abac) suites are the closest in model.** They are also policy-based, often built on XACML, with their own policy languages and specialist skills to match. Moving to one keeps the same shape of program, and often the same rollout effort.

**General-purpose policy engines** evaluate policy written in a dedicated language and leave the rest to you. That means policy distribution, testing pipelines, audit collection and data fetching are yours to build. They are engines, not platforms.

**Relationship-graph authorization systems** model access as a graph of relationships, in the style of Google's Zanzibar. They answer sharing questions well and need a second copy of your relationship data kept in sync.

[**Authorization management platforms**](https://www.cerbos.dev/blog/authorization-management-platforms) pair a decision engine with policy lifecycle, distribution, audit and context in one product. This is the group that replaces PlainID, and it is where Cerbos sits.

*Several of these groups include open source options, mostly engines and graph systems. For a PlainID replacement, the question is not whether the engine is open source but whether everything around it, policy review, distribution, audit and on-premise control, comes with it.*

## Cerbos as a PlainID alternative

Cerbos is an authorization management platform for applications, gateways, workloads and AI agents. Decision points run next to every workload, [Cerbos Hub](https://www.cerbos.dev/how-it-works) manages policy and audit, and [Cerbos Synapse](https://www.cerbos.dev/product-cerbos-synapse) brings in context and connects gateways, data platforms and agents. Here is how it maps to what PlainID customers have today.

### Policy your teams can review and test, at thousands of rules

Cerbos policies are short YAML files with conditions in CEL, the open expression language Kubernetes and Envoy also use. A security reviewer can read "analysts can read accounts in their own region" and check it. Policies live in Git or Cerbos Hub policy stores, and every change goes through the code review your organization already trusts, with [tests](https://www.cerbos.dev/features-benefits-and-use-cases/testable-authorization) that stop a failing policy from ever reaching production. For people who do not write YAML every day, the Cerbos Hub playground generates starting policies and shows a permissions matrix of who can do what.

### Decisions in your infrastructure, and a control plane you can host

Every decision runs inside your infrastructure, and decision points keep serving the last policy they received if Cerbos Hub is unreachable. Cerbos Hub itself is available [on-premise](https://www.cerbos.dev/blog/cerbos-hub-now-available-on-premise) for enterprise customers, including [air-gapped](https://www.cerbos.dev/features-benefits-and-use-cases/self-hosted-authorization) environments. Policy bundles are encrypted with each deployment's own credentials.

### One policy set across applications, gateways, data and agents

Applications call Cerbos through SDKs in eight languages plus Laravel. Cerbos Synapse is the external authorization service for Envoy and Istio. It answers Trino's authorization calls with [row filters and column masks](https://www.cerbos.dev/blog/row-level-security-for-apache-trino) written in Cerbos policy, and governs Kafka topics. Applications you cannot change are covered [at the gateway](https://www.cerbos.dev/blog/guide-add-authorization-to-legacy-applications-no-code-changes). AI agents have every tool call checked before it runs, down to its arguments, with the user behind the agent checked in the same decision. One policy change applies everywhere on the next request.

### Evidence for every decision

Every decision is logged with its inputs, the policy version that produced it and the outcome. Cerbos Hub [collects the logs](https://www.cerbos.dev/features-benefits-and-use-cases/audit-logs) from every decision point into one searchable trail, links each entry to its policy, and exports for archiving. Hub also keeps the build history, so you can show exactly which policy was live on a given day.

### Context at decision time

Cerbos Synapse fetches identity, resource and relationship data from identity providers such as Okta and Entra ID, databases and APIs at the moment of the decision, with caching you configure. Applications send an ID, and the policy gets the full picture.

### Open standards and public pricing

The decision engine at the core, Cerbos PDP, is open source under Apache 2.0 and implements the AuthZEN API. Alex Olivier, our cofounder and CPO, co-chairs the AuthZEN Working Group. Pricing is public.

### Proven at enterprise scale

The Cerbos platform runs [more than 2 billion authorization checks a month](https://www.cerbos.dev/blog/open-source-vs-paid-cerbos). [Utility Warehouse](https://www.cerbos.dev/customers/utility-warehouse/non-human-identities) governs 4,500 services and millions of non-human identities with it. Analysts cover it too, in our posts on [Gartner's AuthZEN research](https://www.cerbos.dev/blog/cerbos-named-sample-vendor-authzen-gartner-hype-cycle-for-digital-identity) and KuppingerCole's [policy-based access management](https://www.cerbos.dev/blog/cerbos-included-inkuppinger-cole-leadership-compass-policy-based-access-management) report.

## When Cerbos is not the right PlainID alternative

If your program depends on masking inside Snowflake or Databricks today, PlainID's native support for those platforms covers it directly. Keep that masking where it runs and move the rest of authorization first. If you want business users to author every rule in a visual console with no review step from security or engineering, Cerbos asks more of your process, by design.

## Moving off PlainID without a big bang cutover

Nobody should switch authorization platforms in one weekend. The safe pattern has four steps.

1. Move one service.  
2. Run Cerbos beside PlainID in shadow mode, making decisions without enforcing them.  
3. Compare every decision until they match.  
4. Then move enforcement.

Start with the service that has the fewest attribute sources, not the most important one. Settle the request shape, the attribute mapping and the tests there, then reuse them for the harder services.

Our [migration guide](https://www.cerbos.dev/blog/migrating-from-plainid-to-cerbos)  covers it step by step. It maps PlainID concepts to Cerbos, gives a worked policy translation with tests, shows where PlainID's attribute sources go, and explains how to run shadow mode and cut over.

[Book a call](https://www.cerbos.dev/workshop) to map your PlainID setup to Cerbos with our team. You will leave with a migration plan, timeline and risk view your security and audit teams can review. If you would rather explore first, [try Cerbos Hub](https://hub.cerbos.cloud/) and test your own policies.

## FAQ

### What are the best PlainID alternatives?

The best PlainID alternatives are authorization management platforms, which pair a decision engine with policy lifecycle, distribution, audit and context, the same job PlainID does. Cerbos is one, with policy as readable code, decisions in your own infrastructure, an on-premise control plane option and public pricing. Identity providers, governance tools and privileged access products often appear on PlainID alternatives lists but do not make fine-grained runtime decisions.

### Is Okta an alternative to PlainID?

Okta is not a direct alternative to PlainID. Okta authenticates users and assigns roles and groups, deciding who gets in. PlainID and Cerbos decide what each person, service or agent can do to a specific resource at runtime. Most enterprises run an identity provider like Okta or Microsoft Entra ID alongside an authorization platform, rather than instead of one.

### Is there an open source alternative to PlainID?

There are open source authorization engines, but a PlainID replacement needs more than an engine. It needs policy review, distribution, audit collection and context. The Cerbos platform includes Cerbos PDP, an open source decision engine under Apache 2.0, together with Cerbos Hub for policy management and audit and Cerbos Synapse for context and integrations.

### How much does PlainID cost compared with alternatives?

PlainID does not publish pricing. It sells by quote after a demo, and independent reviews note significant rollout effort on top of the license. Cerbos publishes pricing, with a \$0 proof of concept, Development from \$25 a month, Production from \$933 a month and custom Enterprise contracts, based on monthly active principals.

### What type of tool is PlainID?

PlainID is a policy-based access control (PBAC) authorization platform. It centralizes authorization policy, evaluates access at runtime and enforces it through prebuilt connectors called Authorizers. It sits in the authorization layer of an identity stack, after authentication by an identity provider, alongside identity governance.

### How do I switch from PlainID without downtime?

You switch from PlainID without downtime by moving one service at a time. Run Cerbos beside PlainID in shadow mode, compare every decision until they match, then move enforcement for that service and repeat. The [migration guide](https://www.cerbos.dev/blog/migrating-from-plainid-to-cerbos) covers the concept mapping, policy translation and testing.
