Identity & access platform for B2B SaaS

## Stop building auth from scratch.  
One identity model for humans, agents, and machines.

One identity model for everyone calling your product — humans logging in, agents acting on their behalf, and services authenticating with mTLS or M2M tokens. Same SDK, same audit, same policy engine.

No spam, ever.

Why Authaz

## Auth wasn't designed for what you're shipping.

AI-native products launch multi-tenant on day one, with agents calling APIs on behalf of users and feature surface that compounds weekly. The auth tools you'd reach for were built for a different decade.

Built for

## Teams building the next generation of SaaS.

If your product has humans logging in, agents calling APIs on their behalf, or services authenticating each other with mTLS or M2M tokens — Authaz is the auth platform you don't have to fight.

Use cases

## Patterns you'll find familiar.

## Ship the product, not the auth.

Join the waitlist for early access — drop in the SDK and get back to building the part only you can.

No spam, ever.

Authentication

## Every way to authenticate. _Human, agent, or machine._

Password, passkey, magic link, OAuth, SAML, MFA, M2M tokens, mTLS-pinned clients, and agent identities — one API, one audit trail, one place to configure. Whoever (or whatever) is calling, you get the same primitives.

Authorization

## Authorization belongs in the platform.

Most auth vendors stop at login. Authaz keeps going — RBAC, ReBAC, per-tenant policy, and a decision log that treats users, agents, and services as first-class subjects. The same rule decides whether a human, an agent, or a backend service can act. No custom middleware, no homegrown role tables.

Multi-tenant model

## How identity actually maps in B2B SaaS.

Tenant isolation isn't a flag in your token — it's how every layer thinks about access. Tokens, policy, and audit all carry organization context by default.

One identity model. Every token, policy, and audit row carries org context — no app-side bookkeeping.

How it works

## Inside the auth path.

Every request lands at a regional edge, picks up tenant context from the resolver, runs through policy, and writes an audit row — all under fifty milliseconds.

Common flows

Configuration

## Ship your whole auth stack _from one file._

Define providers, MFA, sessions, signup, and branding in version-controlled YAML. authaz apply diffs your file against the live tenant and applies the change — from local dev to staging to prod, no clicking around a dashboard.

Developer experience

API-firstREST APISDKsWebhooksTerraform (soon)

## Verify a session in five lines.

SDKs for the languages you ship in. Same primitives, same shape, same docs. No ten-call dance to get a user id.

Webhooks & events

## Wire your stack to identity, not the other way around.

Subscribe once. Replay on demand. Every identity change in your tenant fires a typed event you can route to Slack, your CRM, or your own services.

Idempotency keys, exponential retries, replay window of 30 days.

Local development

## Build against real auth, locally.

Sandbox tenants come pre-seeded with users, orgs, and roles. Local callbacks work out of the box — no ngrok choreography to log in.

Audit & compliance

## Every action logged. _Nothing to build._

Sessions, challenges, policy decisions, admin actions — immutable, filterable, exportable. Your SIEM, your S3, your choice.

White-label

## Make it yours.

Custom domain, custom branding, buyer-provided IdPs — every login page feels like part of your customer's product, not a vendor stopover.

Built for B2B SaaS

## The wedge most identity platforms miss.

B2B SaaS lives or dies on three things: organizations, member access, and tenant-scoped permissions. Authaz is built around them — not around them as paid add-ons.

Enterprise readiness

## Everything enterprise asks for. Shipped, not roadmapped.

The features your largest customers ask about — SAML, SCIM, audit, FGA, multi-region — built into the same SDK as your first user's signup.

Security & compliance

## Security review becomes a checklist, not a project.

Authaz is engineered for SOC 2 and your largest customer's vendor security questionnaire. Encryption, isolation, and rotation aren't add-ons — they're defaults.

Reliability

## Sign-in keeps working — even when AWS doesn't.

Active-active across regions. Automatic failover. The auth path is the last thing in your stack you want flapping.

Migration

## Already on Auth0, Cognito, or homegrown auth?

Most teams that move to Authaz come from one of three places. We have a path for each — and engineers who've done the migration before.

Pricing

## Predictable from your first user to your ten-thousandth tenant.

MAU-based pricing. Security included on every tier. No paywalled SAML.

Where this is going

## One identity control plane for B2B SaaS.

Authaz is being built as the enterprise readiness infrastructure for B2B software — customer, workforce, and machine identity under a single model. Same primitives. Same audit. One contract.

Most teams run three identity stacks: one for customers, one for employees, one for services. Authaz collapses them into one — same model, same SDK, same audit.

active-active, survives a full AWS region failure

When an entire AWS region goes down, your sign-in flow keeps working. Active-active across regions — from your first user to your ten-thousandth tenant, no rewrites along the way.
