## About

Security, Simplified\. That's the lens I bring to every board conversation, every architecture review, and every team I build\. I've spent more than a decade making organisations harder to breach and easier to trust — across two formal CISO mandates, multiple sectors, and security programs built from scratch\. At Yellow\.ai \(global conversational AI SaaS, multi\-region APAC/US/EU\), I built the security function from zero: cloud\-first architecture, DevSecOps pipelines, and a cross\-functional team of 6 — driving measurable, consistent year\-on\-year reduction in high\-risk findings, significant MTTR improvement, and substantially faster remediation cycles\. At Decathlon Sports India \(80\+ stores, 30,000\+ users\), I led cybersecurity and data privacy across a nationwide multi\-cloud retail operation — materially reducing operational cyber exposure through systematic endpoint hardening, network segmentation, and cloud posture improvement\. I also represented India at Decathlon's global CISO forums\. Most recently at Anzen Technologies, I ensured quality assurance and governance standards across a large\-scale portfolio of client security audits and technical assessments — spanning BFSI, eCommerce, Pharma, and IT/ITES\. Across all of it: multi\-framework compliance \(ISO 27001 \| SOC 2 \| PCI DSS \| GDPR \| HIPAA \| DPDPA \| CMMC\), regulatory relationships \(CERT\-In, RBI, SEBI\), and a consistent ability to talk security in the language of risk, not technical noise\. Sectors: AI SaaS · NBFC · BFSI · Retail · Healthcare · eCommerce · Manufacturing Certifications: CISA · CRISC · DCPLA Active community voice: featured at ISMG \(AI in financial services security\), Spotify podcast contributor, and speaker at global CISO forums\.
