ABOUT PRAVEENA MISHRA
Hi, I am a CISSP-certified Senior Security Operations Analyst with a strong background in incident response, threat modeling, vulnerability management, and threat intelligence. I bring a practical and collaborative approach to building resilient security operations. I have about 7 years of experience and I have worked at Akamai Technologies and HPE in the past. My technical expertise includes developing and managing detection and response workflows, optimizing SIEM and EDR tools (Splunk, CrowdStrike, SentinelOne), and supporting DevSecOps practices across cloud environments like AWS and GCP. I’ve also contributed to security engineering initiatives—integrating secure architecture, Vulnerability Management, and automating detection using Python and PowerShell. I work closely with cross-functional teams to identify and mitigate threats, support compliance (NIST, PCI DSS, SOC2), and deliver security solutions that align with both risk priorities and business goals. I’m passionate about staying current with evolving threats, driving continuous improvement in security posture, and contributing to a culture of proactive, data-driven defense.
