Summary
👤
Senior🎓
Top SchoolSergei Polunin is a Security Architect and team leader with nearly a decade of hands-on experience designing and delivering large-scale information security projects for oil & gas, defense, and banking clients. CISSP-, OSCP-, AWS- and MCSE-certified, he blends cloud-native architecture (AWS, Docker, Kubernetes) with practical application security and CI/CD hardening using tools like Snyk, OWASP ZAP and GitHub Actions. He leads end-to-end engagements—from audits and penetration tests to incident investigations and operator training—having delivered 20+ major data security implementations and built a dedicated infrastructure protection team. Known for translating vendor products into production-grade solutions (DLP, AD, remote access) and for creating internal training programs, he also shares practical security insights via a bilingual blog. Less obvious: he routinely negotiates and justifies technical proposals to non-technical stakeholders, bridging engineering rigor with commercial delivery.
