Tanishq Hatwar

I’m a Network Security Engineer II at Cisco Systems (India) Pvt. Ltd, where I monitor security alerts, firewall logs, IDS/IPS events, and SIEM outputs to detect, investigate, and respond to incidents. I manage Cisco NGFW (FTD), ASA, and Firepower Management Center (FMC) policies, owning 70+ customer cases per month with 10+ Priority escalations while coordinating cross-functional war-rooms.

I’ve also built Python and REST API automations that remove repetitive case-handling steps, and I do threat analysis and vulnerability assessments mapped to the MITRE ATT&CK framework. Outside day-to-day operations, I developed NADE (a network attack detection engine using PCAP/live sniffing with Suricata) and an ARP spoofing detector, and I’ve presented trainings on OWASP Top 10, digital forensics, and CTFs at Cisco Security & Offensive Summits.
