Cavinsan Selvaratnam

I am an information security professional with hands-on experience in SOC operations, security monitoring, and incident response across enterprise environments of 600+ endpoints.

I perform L1/L2 triage, correlate events from EDR, firewalls, and vulnerability scanners, and document incidents with detailed IOCs and response actions. I have managed centralized patching, vulnerability assessments, and firewall monitoring to reduce exposure.

I have practical experience with CrowdStrike Falcon, Qualys VM, Palo Alto firewalls, ManageEngine and Atera, and a strong theoretical grounding in Microsoft 365 security, Azure AD concepts, ISO 27001 and NIST CSF. I am developing expertise in Microsoft Sentinel, Microsoft Defender, Entra, and Intune through labs and self-directed learning.

I have contributed SOPs and knowledge-base content, supported ISO 27001 audit activities, and independently identified and investigated incidents that led to containment and remediation. I am seeking an Associate Security Engineer role to strengthen cloud security capabilities and contribute to enterprise threat detection and incident response initiatives.
