Director, Cloud & AI Security
Rajeew Patabendi
I architect zero-trust, AI-aware security programs for regulated financial institutions — currently leading cloud security architecture for RBC, including its OCC-regulated U.S. subsidiary, City National Bank. Based in Calgary, Alberta, Canada.
Focus areas
Zero Trust Architecture
Designing zero-trust reference architectures (NIST SP 800-207) for multi-cloud environments across regulated financial services organizations.
AI Security Posture Management
Building AI-SPM guardrails for enterprise foundation-model platforms — Azure OpenAI, Microsoft Foundry, AWS Bedrock, and self-hosted models — against prompt injection and data exfiltration.
Cloud & CNAPP Strategy
Consolidating fragmented point tools into unified CNAPP platforms (CSPM, DSPM, CIEM, code security) that cut alert fatigue and mean time to remediate.
