Sunil Kumar: Advancing Cybersecurity Research and Product Assurance in the Digital Age
Sunil Kumar, Associate Vice President – Security Research at Deep Armor, stands at the forefront of modern cybersecurity research and assurance. With extensive expertise spanning product security, risk management, and advanced security testing, he has played a pivotal role in helping organizations secure complex digital ecosystems. His work reflects a deep understanding of how emerging technologies—from cloud and mobile platforms to IoT and AI-driven systems—introduce new security challenges that demand both strategic insight and technical rigor.
In his current role, he leads and contributes to comprehensive security research and assessment initiatives that cover the full spectrum of the software development lifecycle. His areas of specialization include threat modeling, secure code reviews, static and dynamic application security testing (SAST and DAST), vulnerability management, and penetration testing. These capabilities extend across web applications, network infrastructures, cloud environments, mobile platforms, IoT products, telecom systems, and increasingly, AI-enabled technologies. His approach emphasizes identifying risks not only at the surface level but also at the design and architectural stages, where vulnerabilities can have the most far-reaching impact.
He has been instrumental in assessing large-scale and highly complex environments, often supporting organizations operating at global scale. His work focuses on uncovering both implementation flaws and systemic weaknesses that could expose products to sophisticated threats. By combining hands-on technical assessments with structured risk analysis, he helps organizations move beyond reactive security toward proactive, resilient design.
At Deep Armor, he is part of a leadership team that supports global enterprises, including Fortune 50 organizations, in embedding security deeply into their engineering processes. The firm is widely recognized for its practical, implementation-driven approach to security, prioritizing real-world impact over theoretical compliance. Through product security assessments, targeted security research, and structured training programs, Deep Armor enables engineering and security teams to build systems that are both robust and trustworthy.
A key differentiator in his work is the ability to translate complex security findings into actionable guidance for developers, architects, and business leaders. He advocates for integrating security early and continuously across the SDLC, ensuring that it becomes an enabler of innovation rather than a bottleneck. His contributions have helped organizations strengthen their defenses while maintaining agility in fast-paced development environments.
Beyond his organizational responsibilities, he is an active and respected contributor to the global cybersecurity community. He regularly shares his research findings and practical insights at leading international forums, including Black Hat USA, the FIRST Annual Conference, FIRST regional events, Insomni’Hack, and ISC2 platforms. These engagements reflect his commitment to advancing collective knowledge and fostering collaboration across the security profession.
Before joining Deep Armor, he gained valuable industry experience as a security engineer at Ola Cabs and Aricent Technologies. In these roles, he focused on strengthening product and network security for both enterprise and consumer-facing platforms. This exposure to high-traffic, real-world systems sharpened his understanding of operational security challenges and the importance of scalable, practical controls.
Throughout his career, he has demonstrated a consistent focus on bridging the gap between cutting-edge security research and real-world implementation. His work continues to influence how organizations approach product security in an era defined by rapid digital transformation, cloud adoption, and AI-driven innovation.
As cyber threats grow more sophisticated and interconnected, his leadership and expertise remain critical in shaping secure, resilient digital products. Through research, collaboration, and hands-on execution, he continues to contribute meaningfully to the evolving landscape of global cybersecurity.
