About

As a Cybersecurity Architect, I design and evolve cybersecurity strategies with a strong focus on Security Operations Center (SOC) operations, detection engineering, threat hunting, and AI-driven security innovation. My work involves building scalable and resilient SOC architectures, where autonomous SOC operations are enabled through AI agents that handle enrichment, correlation, and first-response workflows. Alongside this, I am researching cost-effective SOC ecosystems built around cohesive, task-based and goal-driven investigations, where security activities are decomposed into focused, reusable tasks and dynamically orchestrated based on investigative intent. The aim is to move away from monolithic, tool-heavy SOC models toward outcome-oriented workflows that maximize investigative value while minimizing operational and automation costs. I focus on developing low-code AI agents that streamline SOC workflows while embedding strong security controls into AI-enabled systems. My experience spans network forensics, protocol analysis, and the design of security architectures that balance automation with human oversight. I am driven by the belief that the future of security lies at the intersection of intelligent systems and human context.

Responsible for strategizing SOC operations end to end, spanning detection engineering, threat response, and containment. Drive the fusion of threat intelligence and automation to operate a large-scale SOC processing ~50K detections with a strong conversion rate to confirmed threats.
Lead customer-facing operational strategy discussions focused on detection coverage improvement, blind-spot identification, and response effectiveness. Use MITRE ATT&CK Navigator to clearly communicate coverage gaps, guide mitigation planning, and track progress in an intuitive, threat-aligned manner.
Approach Zero Trust pragmatically as an evolution of established defense-in-depth principles, applying modern identity, telemetry, and automation layers without losing architectural rigor.

Served as a level-4 escalation engineer focused on protocol-level analysis and optimization in security-enforced environments. Used Wireshark-driven, hypothesis-based investigation to identify and correct performance degradation caused by encryption, tunneling, inspection, and policy enforcement. Tuned transport-layer behavior including TCP window scaling and congestion dynamics to restore throughput and stability under VPN, proxy, and IPS overhead. Architected and optimized secure traffic paths involving DM VPNs, reverse proxies, deep packet inspection, and Snort-based IPS, with primary emphasis on transport-layer acceleration while preserving security efficacy.

Sr. Network Specialist

Nov 2012 – Jul 2016 · 3 yrs 8 mos · Cochin Area, India

As a Senior Network Specialist with IBM, I have successfully served clients from diverse industries, including banking and manufacturing. This unique experience has allowed me to develop a deep understanding of the specific challenges and requirements within these sectors.
Working with banking clients, I have gained invaluable insights into the criticality of maintaining robust security measures to protect sensitive financial information. I have implemented stringent access controls, monitored for suspicious activities, and conducted thorough risk assessments to ensure compliance with regulatory standards such as PCI-DSS. Additionally, I have involved in the implementation of secure payment gateways, IPV6 transformation & enhanced authentication protocols to fortify the overall security posture of banking systems.
In the manufacturing industry, I have focused on addressing the unique security concerns associated with industrial control systems (ICS). I have worked closely with clients to secure their production environments, protect intellectual property, and prevent disruptions to critical manufacturing processes. By implementing network segmentation, intrusion detection systems, and conducting regular vulnerability assessments, I have helped manufacturing clients mitigate the risks associated with cyber threats and maintain uninterrupted operations.
My ability to concurrently manage clients from both the banking and manufacturing sectors has allowed me to draw upon best practices from each industry, adapting and applying them to deliver comprehensive security solutions.
Overall, my experience working with clients from banking and manufacturing has provided me with a well-rounded perspective on the unique security challenges faced by organisations in these sectors. It has allowed me to develop a versatile skill set & a deep understanding of the intricacies involved in protecting critical assets and maintaining a strong security posture across different industries.
