Zero-Trust Identity Platform for Enterprise SSO
Deployed a centralized identity broker supporting SAML 2.0, OIDC, and FIDO2 WebAuthn across 40+ SaaS applications, reducing account takeover incidents by 96%.
96% Fewer ATO Incidents40+ App IntegrationsPasswordless Auth
Key Takeaways
- Phasing out passwords in favor of FIDO2 hardware keys and WebAuthn eliminated credential stuffing across 5,000 enterprise employees.
- Real-time contextual risk engine evaluates device posture and network telemetry before granting application sessions.
- Centralizing 40+ enterprise SaaS apps behind a hardened Keycloak cluster reduced helpdesk password tickets from 200+ to 11 per week.
The Challenge
A 5,000-employee enterprise managed credentials across 40 disparate SaaS tools with no unified directory. Credential reuse resulted in 48 confirmed account takeover (ATO) incidents annually, while IT helpdesks spent 200+ hours monthly resolving manual password reset requests.
Architecture & Technical Approach
- Identity Broker Cluster: Deployed a hardened, multi-region Keycloak cluster extended with custom Java SPIs for adaptive risk scoring.
- FIDO2 WebAuthn Deployment: Rolled out YubiKey 5 hardware keys and platform biometrics (Touch ID, Windows Hello) for passwordless authentication.
- Continuous Risk Scoring Engine: Evaluates device MDM compliance, geographic velocity, and network reputation on every session handshake.

Production Reliability & Lessons Learned
Deploying LDAP-to-OIDC translation proxies allowed legacy internal tools to benefit from modern WebAuthn MFA without modifying legacy application code.
