Access Management Platform

Regain control of your authorizations

One collaborative platform where security, product, and engineering teams define access policies together—in plain language everyone understands.

Write your rules like this:

"A user can approve a payment if they have the 'manager' role, the payment is linked to their assigned branch, and the amount does not exceed their approval limit."

The missing link in your IAM ecosystem

Big ACL acts as a Policy Administration Point in your architecture,
connecting IAM, IGA & ITSM to give you a single control plane
for Access Management.

Big ACL as Policy Administration Point in the IAM & IGA ecosystem.

IGA platforms provision identities.

Identity Providers centralize authentication.

Ticketing systems drive access requests and approvals.

Enterprise Architecture provides metadata and ownership.

SaaS & Cloud consume normalized access policies.

Policy Decision Points (OPA, AVP) enforce policies generated by Big ACL.

Rule Management

Create, validate, and deploy access rules

Big ACL provides a complete environment to manage your authorization rules from creation to production.

Write rules in plain language: Define who can do what using natural language. No code required. Business and security teams can read, write, and validate rules directly.
Validate before you deploy: Auto-generated test cases verify each rule. Catch conflicts and regressions before they reach production.
Translate to Cedar & Rego: Rules are automatically translated into policy languages for OPA, AWS Verified Permissions, or your own enforcement layer.

Entity Schema

Coherent Access Rules

Big ACL is a policy modeling layer that turns human-readable authorization rules into standard policy languages like Cedar and Rego.

As you define rules, Big ACL also generates an entity schema — a shared, versioned map of your users, roles, resources, and their relationships. This schema provides the structure that keeps access rules coherent and aligned across teams and systems.

Every rule is validated against the schema before translation, ensuring consistency, preventing drift, and catching errors early in your workflow.

Schema-anchored Policy

Rule

A user can validate an operation if they have the 'manager' role, the operation is associated with their assigned branch, and the operation's amount does not exceed the user's approval limit.

Entity Schema

Testing

Complete test coverage, rule by rule

With Big ACL, every authorization rule comes with automatically generated test cases. Each rule is exercised across valid and invalid scenarios, ensuring its behavior is precise, predictable, and aligned with your intent.

This built-in testing makes policies safer to evolve. As your schema or rules change, Big ACL regenerates test cases to catch regressions before they reach production—giving your team confidence in every deploy.

Why Big ACL?

Built for modern authorization challenges

Whether you're scaling a startup or managing enterprise complexity, Big ACL gives you the tools to handle authorization the right way.

One source of truth for all teams: Product, engineering, and security teams work from the same policy repository. No more scattered rules across codebases, conflicting interpretations, or tribal knowledge about who can do what.
Decouple policy from application code: Stop embedding authorization logic in your codebase. Externalize policies to make your applications cleaner, easier to audit, and simpler to maintain. Change rules without redeploying code.
Audit-ready and compliant: Every policy change is versioned and traceable. Demonstrate to auditors exactly who has access to what, when rules changed, and why.
Ship features faster: Developers focus on building features, not reinventing authorization. Big ACL deploys rules directly to your Policy Decision Points (OPA, AWS Verified Permissions), letting product and security teams manage access independently.
