Arunkumar Udaiyar

I am a proactive SOC Analyst with hands-on experience in 24x7 security monitoring, threat hunting, and automated incident response using SIEM, EDR, and SOAR platforms. I have mapped adversary behavior with MITRE ATT&CK and Cyber Kill Chain, developed SOAR playbooks that cut response times by 25–35%, and built Splunk dashboards and correlation searches to improve visibility across endpoints and networks.

My background includes triaging L1–L2 incidents, investigating phishing and email compromise campaigns, collaborating with network and firewall teams to block malicious infrastructure, and correlating CVE data to prioritize vulnerability remediation. I am committed to strengthening enterprise defenses and delivering measurable SOC performance improvements.
