How teams ship secure auth with AuthDeep

Real-world deployments across healthcare, fintech, and enterprise SaaS — self-hosted, compliant, and in full control.

Healthcare SaaS

Regional Health Platform

HIPAA-compliant multi-tenant identity for 40+ clinical tenants

Challenge

A healthcare SaaS platform serving regional clinics needed HIPAA-compliant authentication without sending PHI through a third-party cloud identity provider. Every session and audit trail had to remain inside their own infrastructure.

Solution

AuthDeep deployed as a self-hosted gateway in the platform's AWS VPC. HttpOnly opaque sessions prevent any JavaScript-readable token from touching the browser. The audit log captures every login, permission change, and admin action with tenant context. MFA (TOTP + WebAuthn) is enforced for all clinical staff.

Outcomes

  • 40+ clinic tenants onboarded with isolated identity namespaces
  • Zero third-party identity vendor — PHI never leaves the VPC
  • HIPAA Technical Safeguard requirements satisfied out of the box
  • Automatic session logoff enforced by gateway policy

AuthDeep gave us a HIPAA-ready auth layer we actually control. The audit trail and tenant isolation were exactly what our compliance officer needed.

Payment Infrastructure Provider

API key management and gateway security for financial services

Challenge

A payment infrastructure provider needed a secure API gateway that could enforce per-customer rate limits, rotate API keys without downtime, and log every upstream request with a verifiable audit trail — all without trusting a public SaaS identity service with financial operation metadata.

Solution

AuthDeep's governed API key lifecycle was deployed in front of the payment API surface. Per-service scopes ensure a key issued for reporting cannot trigger payment operations. The gateway enforces rate limits at the tenant layer, while edge security controls help detect and block credential-stuffing attempts before they reach the origin.

Outcomes

  • API key rotation with zero-downtime dual-key overlap
  • Per-service scopes prevent privilege escalation across API surfaces
  • Cloudflare edge blocks scraping and credential-stuffing at the perimeter
  • Audit history supports financial services compliance requirements

The scoped API key system and gateway-level rate limiting cut our fraud surface dramatically. We control the entire auth stack now.

Enterprise Workflow Platform

SSO and multi-tenant RBAC for enterprise customers

Challenge

An enterprise workflow platform needed to offer SSO to large customers without requiring each customer to trust a third-party identity provider. Custom RBAC rules per tenant and seamless onboarding without IT overhead were key requirements.

Solution

AuthDeep's multi-tenant architecture with per-tenant IDP binding lets each enterprise customer bring their own OIDC provider. The onboarding wizard guides admin users from account creation through organization setup, IDP configuration, and team invite — all in a single guided flow. Role assignments are tenant-scoped and enforced at the gateway.

Outcomes

  • Enterprise SSO with per-tenant OIDC provider binding
  • Guided 6-step admin onboarding reduces IT support tickets
  • Tenant-scoped RBAC enforced at the gateway — not the application layer
  • Subdomain routing with custom domain support for white-label deployments

Our enterprise customers love that they can bring their own identity provider. The onboarding flow made the rollout painless for IT teams.
