Role-Based Access Control

Permissions that don't turn into spaghetti.

RBAC and ABAC built on a real role and permission registry, a tested policy engine, and an admin UI for assignment — with an audit log of who can do what. Access control designed to grow as your customer base does, instead of a hundred if-statements you're afraid to touch.

One place that decides who gets in.
01The idea

Your permission logic is scattered across a hundred if-statements.

It rarely starts as a mess. One check in a route handler, another in a template, a third buried in a service method — each reasonable on its own. Then a customer wants a custom role, someone asks who can actually see billing, and nobody can answer without reading the codebase. The fix isn't more if-statements; it's a model. We pull access decisions into one place: a registry of roles and permissions, a policy engine the whole app asks instead of deciding for itself, and an admin UI so changing access doesn't mean a deploy. Granular when you need it, readable always, and built to evolve as you grow.

02The signs

Access control has outgrown the if-statements.

Each prompt has the same answer — a model in one place, not logic spread everywhere.

  • 01

    Permission checks are if-statements everywhere

    One policy engine the whole app asks, instead of scattered logic.

  • 02

    Customers want their own granular roles

    A permission registry that composes into roles you can shape.

  • 03

    You can't tell who has access to what

    Access becomes a query, not a forensic read through the code.

  • 04

    Changing a role means a code deploy

    An admin UI where the right people assign access safely.

  • 05

    A role change feels too risky to make

    Policy tests in CI that fail when access quietly changes.

03What we build

The pieces that make access legible.

Structured where it should be, flexible where you need it.

04Defense in depth

Five stages from a role to a recorded decision.

  1. 1Roles
  2. 2Permissions
  3. 3Policy
  4. 4Enforce
  5. 5Audit

No single check decides access in isolation. Roles map to permissions, permissions feed the policy, the policy is enforced consistently across the app, and every decision lands in the audit log — so you can always answer who can do what, and prove it.

05The model

RBAC, ABAC, or the hybrid you actually need.

We start from one source of truth: a registry of fine-grained permissions, composed into roles your team and customers can reason about. Roles handle the broad strokes; attributes — ownership, tenancy, context — handle the cases that genuinely need them. The result is granular where it matters and simple where it doesn't, without over-engineering the easy paths.

  • A permission registry, not scattered checks
  • Roles composed from fine-grained scopes
  • ABAC for ownership, tenancy, and context
  • Granular where it counts, simple elsewhere

06The engine

One place every access decision runs.

Instead of each part of the app deciding for itself, every check asks a single policy engine — custom when the model is small and stable, OPA or Cerbos when rules get rich or need sharing across services. We help you choose honestly rather than by fashion, and either way the rules live in one place, versioned and readable, so changing access is a deliberate edit, not a treasure hunt.

  • A single engine, asked everywhere
  • Custom, or OPA / Cerbos when it fits
  • Rules versioned, readable, in one place
  • Chosen on the model, not on hype
07The surface

Change access without shipping a deploy.

Assigning a role or adjusting a permission shouldn't mean a release. We build an admin UI where the right people see roles, assign them to users, and understand exactly what each one grants — with inheritance and sensible defaults so granularity doesn't become chaos. Config-as-code stays for what should be reviewed in PRs; the day-to-day lives in the UI.

  • Assign and adjust roles, no deploy
  • Inheritance and sensible defaults built in
  • See what each role actually grants
  • Config-as-code for the parts that need review

08How we work

From scattered checks to one model.

01

Map what exists

We catalogue the scattered checks and what each one really enforces today.

02

Design the model

A permission registry and a role design — RBAC, ABAC, or the hybrid you need.

03

Stand up the engine

A single policy engine — custom or OPA/Cerbos — that every check asks.

04

Build the admin UI

A safe surface for assignment, with inheritance, defaults, and an audit log.

05

Test and evolve

Policy tests in CI, then small tested additions as roles grow with you.

09Right when

Access control became the thing slowing you down.

  • Permissions are if-statements everywhere

    Access logic grew check by check, and now adding one means hunting through a hundred files.

  • Customers want granular roles

    Three hard-coded roles aren't enough — buyers want auditors, billing managers, and custom scopes of their own.

  • You can't answer 'who has access?'

    The question has no answer short of reading code, and that's no longer good enough for customers or auditors.

11Questions

The things teams ask first.

First we find them. Permission logic that grew organically usually hides in route handlers, templates, service methods, and the occasional database query — and no two checks are written the same way. We catalogue what each one actually enforces, then pull the decisions into one place: a policy engine that every part of the app asks instead of deciding for itself. The scattered if-statements become a single, readable set of rules, and adding a new check stops meaning hunting through a hundred files.

Untangle access before it tangles you.

Tell us where your permission logic lives today and what's forcing the change — a customer asking for custom roles, an audit, or just one if-statement too many. We'll map what you have and put a model in place: a registry, a tested policy engine, an admin UI, and an audit log built to grow with you.
