We help companies design, implement, and audit authentication systems that protect users and scale with confidence.
End-to-end design and integration of OAuth 2.0 and OpenID Connect flows — authorization code, PKCE, client credentials, and token lifecycle management.
Deep assessment of your API authentication layer. We test token handling, session management, rate limiting, and identify vulnerabilities before attackers do.
Design and rollout of multi-factor and passwordless authentication — WebAuthn, passkeys, TOTP, and adaptive risk-based step-up policies.
Build the right identity foundation. We architect SSO, federation, SCIM provisioning, and role-based access control tailored to your infrastructure.
Align your auth systems with SOC 2, HIPAA, PCI-DSS, and GDPR requirements. We document controls and prepare you for audits.
Move off legacy auth. We handle migrations from homegrown systems to modern identity providers — zero-downtime, with full data integrity.
We map your current auth landscape — endpoints, flows, token lifetimes, third-party integrations — and identify every risk surface.
We design a target-state authentication architecture with clear protocol choices, provider recommendations, and migration paths.
We embed with your engineering team to build, test, and deploy — writing production code, not just slide decks.
Penetration testing, token abuse scenarios, and adversarial review. We stress-test every flow before you go live.
