About Sreeraj R

OT/ICS Cyber Security Analyst with hands-on experience securing industrial and critical infrastructure environments.I specialize in OT SOC monitoring, incident response, and threat detection across SCADA and ICS networks. My experience includes working with Claroty Secure Remote Access (SRA) and Continuous Threat Detection (CTD), Nozomi Networks, SolarWinds, IBM QRadar (SIEM), and Palo Alto XSOAR (SOAR) to identify threats, prioritize alerts, and reduce operational risk.Currently, I support 24×7 OT SOC operations, handling continuous monitoring and incident response activities. I regularly perform alert triage, investigation, containment, and mitigation while aligning security operations with the Purdue Model (Levels 0–5).I am particularly interested in roles focused on OT SOC, ICS security, and critical infrastructure protection within energy, utilities, manufacturing, and industrial environments.
