Mayank Choudhury — Operations Associate

For work opportunities or further queries, I can be reached at: messagemayank07@gmail.com I am a cybersecurity professional with 5+ years of hands-on experience across Security Operations, Incident Response, Digital Forensics, Threat Intelligence, and Proactive Threat Hunting. I specialize in developing robust detection strategies, conducting deep-dive investigations, and managing the complete incident lifecycle within complex enterprise environments. My expertise includes advanced threat hunting using log telemetry, endpoint artifacts, network analysis, YARA/Sigma-based techniques, anomaly detection, and MITRE ATT&CK mapping. I also bring strong capabilities in AI-driven security analytics, leveraging machine learning and behavioral-based detection techniques to identify advanced threats, reduce false positives, and enhance SOC efficiency. I focus on integrating AI into detection engineering, threat intelligence enrichment, and proactive defense strategies. My experience spans incident response for malware outbreaks, credential compromise, lateral movement, cloud intrusions, data exfiltration, and privilege escalation. I am well-versed in SOC operations including alert triage, root-cause analysis, playbook development, response automation, and SIEM rule optimization. Technically, I have worked with tools such as Splunk, Sentinel, QRadar, CrowdStrike Falcon, Defender ATP, Tanium, Elastic, Wireshark, Velociraptor, OSQuery, and threat intelligence platforms like Anomali, MISP, VirusTotal Enterprise, and Recorded Future. Beyond technical expertise, I actively apply psychology-driven consulting principles to understand attacker behavior as well as human decision-making within organizations. This helps in improving security awareness, strengthening defense strategies, and enabling better risk-based decision making. I bring a threat-driven, intelligence-led approach focused on understanding adversary behaviors, enhancing detection maturity, and reducing MTTD/MTTR. I am passionate about adversary simulation, purple teaming, exploit chain analysis, and continuously evolving enterprise defense strategies. I am also interested in life coaching and mindset development, helping individuals build clarity, confidence, and resilience alongside technical excellence.
