Linx Security appoints Sarit Reiner Frumkes as CTO
Former Payoneer CTO and Microsoft VP brings over two decades of expertise in enterprise security, scaling startups within enterprises, and driving strategic growth.
Linx Security, which develops modern identity security and governance solutions, announced on Monday the appointment of Sarit Reiner Frumkes as Chief Technology Officer (CTO). Sarit will lead Linx’s technology strategy, product innovation, and research initiatives.
Sarit joins Linx with a distinguished career spanning Microsoft, Payoneer, and the Israeli Prime Minister’s Office. Sarit served at the Israeli Prime Minister’s Office cyber division for over 20 years. Later, she joined Microsoft, becoming VP of Product and Engineering, where she led the integration of CyberX, Aorato and Adallom—acquired for nearly $500 million combined—into Microsoft’s security ecosystem. In her last position as CTO of Payoneer, she led platform innovation and system modernization while driving the secure and compliant growth of one of the world’s largest financial infrastructures.
Since emerging from stealth in 2024 with a $33 million funding round led by Index Ventures and Cyberstarts, Linx has continued to scale and is poised to double its workforce by 2025.
“I’ve spent my career navigating the evolving cybersecurity threat landscape, and one thing has remained constant—identity is at the heart of nearly every major security breach,” said Sarit Reiner Frumkes, CTO of Linx Security. “Linx is tackling one of the biggest security challenges today—ensuring enterprises can seamlessly manage and secure identity at scale. With a modern, automated approach, we’re redefining how organizations protect access in an increasingly complex environment. I’m excited to build on this strong foundation and drive the next phase of innovation and growth.”
