Atsign has appointed Aparna Rayasam as Chief Executive Officer. She will lead the company’s next phase of growth, focusing on delivering foundational security and governance for the emerging era of agentic AI.
Rayasam brings extensive expertise in product strategy, platform architecture, engineering, and threat research. She has a proven track record of scaling security portfolios into multi-billion-dollar market leaders, driving double-digit growth, and delivering award-winning products.
"Aparna is exactly the leader this chapter requires," said Kim Perdikou, Chair of the Board at Atsign. "She is recognized for setting a clear vision, delivering award-winning products, and building customer-first cultures. The AI wave is fundamentally reshaping enterprise architecture, and Aparna’s deep expertise will accelerate our mission to secure all enterprise software against AI-driven threats, while simultaneously enabling the safe deployment of next-generation AI data centers and multi-agent systems."
"Enterprises are racing to adopt AI, but traditional architectures are compounding risk by prioritizing velocity over safety," said Rayasam. "At Atsign, we are flipping the script on AI adoption, speed, and security. By providing a comprehensive solution that is secure first, we are empowering enterprises to protect their existing infrastructure from automated threats while allowing developers to build, deploy, and sustainably control multi-agent systems with absolute confidence."
As traditional AI development architectures struggle to scale safely, Atsign AI Architect delivers embedded security protection, robust agent governance, and full support for on-premise and air-gapped deployments. The platform leverages Atsign’s Zero Exposure security model, which eliminates traditional attack surfaces.
Colin Constable, CTO of Atsign, added: "We didn't just build another AI product; we engineered a Zero Exposure architecture that fundamentally eliminates the vulnerabilities of traditional security. Aparna is a powerhouse. Her unmatched track record of scaling multi-billion-dollar security portfolios is exactly what we need to turn this technological breakthrough into the undisputed standard for enterprise AI."
