The threat surface of agentic AI is fundamentally misunderstood by most enterprises. I'm building the framework to fix that.

One life.
Two worlds.

I grew up in Chennai speaking Tamil, dreaming big. A Master's took me to Melbourne where I built a career, a family, and a home. Then the cloud called louder — and AWS brought me to San Francisco.

Seventeen years in cybersecurity means I've seen every threat wave — from network perimeters to cloud to now the agentic AI frontier. I don't just defend systems. I think about where the next blind spot is before it becomes a breach.

" Security isn't a product. It's a posture. And in 2026, that posture must account for autonomous AI agents. "

Agentic AI Security

Most enterprises are deploying AI agents without understanding the attack surface they're creating. I'm documenting it, building defenses, and teaching the industry.

01 — DETECT
Behavioral Pipelines
Four-layer security pipeline: INGEST → EXTRACT → MODEL → RESPOND. Real-time behavioral anomaly detection for AI agents.
02 — ANALYZE
Memory Exfiltration
Cross-session memory write-back attacks are an emerging threat vector that auditors haven't caught up to yet.
03 — DEFEND
Agent Defense Patterns
Least privilege, trust boundaries, and behavioral baselines for autonomous systems that operate across security perimeters.
