Background

About Manigandan Sekar

I'm a Cybersecurity Lead with over 9 years of experience working across various sectors like banking, finance, healthcare, energy, travel, textiles, and manufacturing. I’ve had the opportunity to handle multiple clients globally — including teams from the US, UK, and Middle East — and worked closely with them to strengthen their security posture. One of the highlights of my journey has been leading the full setup of a SOC operation from scratch. From designing processes to building detection use cases, automation workflows, and tuning tools like Sentinel and Splunk — I handled it end to end. I’ve also helped reduce Azure compute costs on SIEM machines and supported license planning for SOP preparation, helping clients optimize budget and efficiency. I'm hands-on with a wide range of tools including Defender, CrowdStrike, QRadar, Zscaler, Netcraft, Portal26 ai prompt security, GuardDuty, Qualys, SailPoint, and many more. I’ve been involved in handling phishing and impersonation takedowns, incident response, bug bounty escalations, VM and Pentest cases — following through till resolution using ServiceNow and Jira. I have also taken lot of interviews in last 4 years to onboard talented people into the company and also to the project. I enjoy mentoring teams, leading shifts, and making sure ticket audits and platform issues are resolved properly. With a Master's in Information Security & Cyber Forensics, I’ve always believed in learning, sharing knowledge, and working with integrity. Currently in a lead role, I’m aspiring to grow into a Security Manager position where I can take more ownership, guide teams, and contribute to a bigger security vision.
