About Karthikeyan Ragunathan

Over two decades of experience in IT and Cybersecurity, I’ve led teams and programs that safeguard organizations against today’s most advanced threats. My focus is on building resilient defenses, driving incident response at scale, and guiding customers through the challenges of securing their digital infrastructure. I believe cybersecurity is more than defending systems—it’s about safeguarding the future. Driven by curiosity and purpose, I continue to embrace every challenge as an opportunity to make a meaningful impact.
