PALO ALTO, Calif., Oct. 20, 2026 /PRNewswire/ — Armadin, an AI-native cybersecurity company building effective autonomous security, today announced that Vasu Jakkal has joined the company as Chief Strategy and Business Officer. Jakkal brings more than two decades of experience in cybersecurity and enterprise technology, most recently serving as Corporate Vice President of Security at Microsoft. She previously served as Executive Vice President and Chief Marketing Officer at FireEye, where she worked alongside Armadin CEO Kevin Mandia.

Jakkal joins as Armadin expands its enterprise footprint following the launch of Armadin Red. She will lead strategy, strategic partnerships, marketing, communications, customer success, and corporate development, and report to Kevin Mandia. Her appointment brings proven experience scaling a security business inside one of the largest technology companies in the world.

She brings a rare combination of operational excellence and strategic vision we will leverage to establish the industry standard for Armadin’s customer experience from the front lines to the board room.”

“In the agentic era, the asymmetry of attacks is accelerating, and the barrier to entry for attackers is collapsing” said Vasu Jakkal, Chief Strategy and Business Officer, Armadin. “Security has never been more important for trust, and it starts with knowing what an attacker can reach and how to prevent that. Armadin delivers leaders proof at agentic speed, so security becomes preventive versus reactive. Security is a team sport and I’m thrilled to join Kevin and team Armadin to build a safer world for all, with all.”

Jakkal’s appointment follows Armadin’s Series B funding round, co-led by Accel and Andreessen Horowitz, and comes as the company extends the reach of its agentic attack campaigns in production for Fortune 500 enterprises and government customers.
