Ashish Popli
FOUNDER & CEO
Engineer. Red Teamer. Security Leader. Investor. Builder.
I started on the offensive side. Red teaming, breaking into systems, learning that exploitability depends on conditions, not just presence. That instinct stayed with me through years of security engineering and vulnerability management at enterprise scale, and through building ML systems that detect patterns in noisy data at massive volume.
Then I became the buyer. Three CISO roles, building security programs from zero at companies growing from early revenue through IPO. The gap between what tools report, what analysts can investigate, and what's actually exploitable never closed. Log4J made it visceral. War room open, five teams demanding answers simultaneously, leadership asking for blast radius, engineers asking if their service is affected, and security scrambling to check conditions across hundreds of resources manually.
Investing in and advising 10+ security startups taught me how startups fit into the larger ecosystem, what problems are worth building companies around, and what it takes to be a founder.
Then classical ML, generative AI, and graph modeling caught up with the problem. A career building security tools and ML systems taught me that vulnerability management isn't an operations challenge. It's a product problem. Defendermate is that product, built for the post-AI era.
