About Yashi
Cyber Security Analyst & Consultant specializing in SOC operations, SIEM monitoring, and enterprise incident response. I protect digital assets and minimize corporate risk by transforming complex log telemetry into actionable threat detection, leading rapid root-cause investigations, and enforcing Zero Trust architectures. Backed by an MSc in Cyber Security Engineering and certified ISO 27001 Internal Auditor expertise, I seamlessly bridge the gap between technical defense (Splunk, Qualys, M365 Security) and strict NIST/GDPR compliance to deliver hardened, audit-ready environments.
