IAM Implementation & Advisory

The convenience of a
modern IAM platform.
Without the limits.

Third-party IAM platforms handle the infrastructure. We handle everything else — the custom flows, complex permission models, and edge cases that require real expertise to get right. The best of both.

The reality

Modern IAM platforms have a steep implementation curve

Modern IAM platforms market themselves as plug-and-play. For simple use cases, they are. The moment you need multi-tenant RBAC, custom authorization policies, enterprise SSO, or a migration from a legacy system — the complexity compounds fast.

Most teams underestimate it. They get most of the way there, then hit edge cases that documentation doesn't cover. Or they build something that works today but creates security and flexibility debt they'll discover when it's harder to fix.

Custom token claims and authorization logic
Fine-grained permissions that don't fit the platform's defaults require custom actions and careful design.
Multi-tenant access models
Isolating data and permissions across organizations is where most implementations get it wrong.
Enterprise SSO edge cases
SAML attribute mapping, SCIM provisioning quirks, and IdP-specific behaviors that documentation doesn't cover.
Migrations without regressions
Moving from a homegrown system or between platforms without breaking existing users or losing permission data.

What we do

Implementation from scratch, migration from legacy systems, or validation of what your team has already built — scoped to what you actually need.

IAM Implementation — Client Side
Build
Full implementation of authentication and authorization on the frontend — login flows, session management, token handling, protected routes, and user context. Built to your product's UX requirements, not a boilerplate.
Auth0, Okta, Cognito, or custom IdP
React, Next.js, and major frontend frameworks
OAuth 2.0, OIDC, token refresh patterns
IAM Implementation — Server & API Side
Build
Backend authentication and authorization — JWT validation, API protection, custom authorization logic, machine-to-machine flows, and token introspection. Includes authorization policy design for complex permission models.
Token validation and middleware
Custom authorization actions and rules
M2M and service-to-service auth
IAM Migration
Migrate
Migrating from a homegrown auth system, a legacy identity provider, or between modern platforms. We plan the migration, handle user data, preserve permissions, and validate the cutover — with zero disruption to existing users.
User import, password migration, and account merging
User federation across identity providers and directories
Permission data mapping, validation, and cutover
Role-Based Access Control
Design + Build
RBAC architecture designed for how your product actually works. Role definitions, permission scoping, multi-tenant access models, and least-privilege enforcement — implemented and tested, not just documented.
Role and permission taxonomy
Multi-tenant isolation models
Custom claims and authorization policies
SSO Integration
Build
Enterprise SSO implementation for B2B products — SAML and OIDC connections, IdP configuration, attribute mapping, SCIM provisioning and deprovisioning, and just-in-time user creation.
SAML 2.0 and OIDC
Okta, Azure AD, Google Workspace, PingFederate, and others
SCIM provisioning and deprovisioning
Implementation Validation
Validate
A structured expert review of your existing IAM implementation — configuration, token security, session handling, and compliance alignment. Delivered as a prioritized findings report with specific remediation guidance.
Configuration and security review
Token and session security
SOC 2 access control alignment
Who we help

Two ways to work with us

Some teams want to outsource the implementation entirely. Others have built it themselves and want an expert to validate the work before it matters.

Outsource
We build it for you
You're building a product and don't have IAM expertise on the team. You need someone who's done this before to implement it right the first time.
Startups launching with Auth0 or Okta for the first time
Teams adding enterprise SSO to close a B2B deal
Platforms building multi-tenant RBAC from scratch
Companies migrating off a homegrown auth system
Validate
We review what you built
Your team built the auth layer. It works — but you're about to go through a SOC 2 audit, close an enterprise customer, and you want to know if it was done correctly.
Pre-SOC 2 access control review
Enterprise prospect security questionnaire incoming
New CTO inheriting an existing implementation
Post-migration validation before going live
Process

How an engagement starts

Every engagement is scoped to the actual problem — not a standard package. Here's how we get from first conversation to work underway.

01
Free scoping call — 30 minutes
We talk through your stack, your timeline, and what you're trying to accomplish. You leave with clarity on scope and cost regardless of whether we proceed.
02
Fixed-price proposal within 48 hours
A defined scope, deliverable, timeline, and price. No ambiguity about what you're buying or what it costs.
03
Implementation or review
We work directly in your codebase, your IAM tenant, your infrastructure. Async-friendly, documentation-first, no black boxes.
04
Handoff, training, and knowledge transfer
Your team owns everything we build or review. We document decisions, edge cases, and rationale — and train the team members who will own ongoing support and management.
