Identity Is the New Security Perimeter
In a world of cloud workloads, remote access, and dissolving network boundaries, identity has become the primary control plane for security. Compromised credentials remain the number one attack vector in breaches worldwide — and most organizations still rely on password-centric approaches that sophisticated adversaries exploit routinely.
Daniel Ossio designs identity-first security architectures that enforce least-privilege access, continuous verification, and robust authentication across every system, application, and API endpoint. Every IAM strategy is grounded in 25+ years of understanding how access controls fail — and how to build them to succeed.
IAM Services
Authentication Architecture
Designing passwordless and multi-factor authentication systems. FIDO2, biometrics, certificate-based auth, and adaptive risk-based authentication strategies.
Privileged Access Management
Securing administrative and service accounts. Just-in-time access, session recording, credential vaulting, and break-glass procedures for emergency access.
Identity Governance
Lifecycle management from onboarding to offboarding. Role mining, access certification campaigns, separation of duties enforcement, and orphan account detection.
Zero Trust Identity
Implementing continuous verification models: device trust, contextual access policies, micro-segmented authorization, and real-time risk scoring per session.
Hybrid Identity Challenges
Modern organizations operate across on-premises Active Directory, cloud identity providers, SaaS applications, and legacy systems — each with its own authentication model. Daniel specializes in designing unified identity fabrics that provide consistent security and user experience across these disparate environments.
- SSO Architecture: Designing single sign-on across cloud and on-premises applications with federation standards (SAML, OIDC)
- Directory Consolidation: Migrating and consolidating identity stores while maintaining security and availability
- API Security: OAuth 2.0 and API gateway security patterns for machine-to-machine authentication
- Trusted Computing: Hardware-backed identity verification, TPM integration, and device attestation
