Xeris names new CEO and CTO to push into AI agent security

By AI, Created 10:12 AM UTC, May 20, 2026, /AGP/ – Xeris appointed cybersecurity pioneer Shlomo Touboul as CEO and Reffael Caspi as CTO on April 30, 2026, as the Tel Aviv company targets the emerging Guardian Agent market. The move puts Xeris’s real-time AI agent governance technology at the center of a fast-growing enterprise security problem: controlling autonomous agents while they are executing tasks.

Why it matters: - Xeris is positioning itself around a new security category for AI agents that operate autonomously across enterprise systems. - The company is betting that real-time governance during execution will become necessary as AI agents generate code, gain new capabilities and behave in non-deterministic ways. - The strategy could shape how enterprises secure both internal agents and customer-facing agents across cloud and on-premises environments.

What happened: - Xeris appointed Shlomo Touboul as CEO and Reffael Caspi as CTO on April 30, 2026. - The company said the leadership changes strengthen its push into the emerging “Guardian Agent” market identified by Gartner. - Touboul is a cybersecurity veteran who founded Finjan in 1996. - Xeris is based in Tel Aviv, Israel.

The details: - Xeris’s core product is a patent-pending Super AI Agent that operates alongside each AI agent. - The Super AI Agent monitors and controls execution in real time. - The system is designed to understand an agent’s intent, reasoning and underlying logic. - The technology detects agent evolution, including code creation, new capabilities and non-deterministic behavior. - Xeris says the control layer works in parallel with AI agents rather than after execution. - The company says the platform secures strategic on-premises agents and customer-facing agents across multiple cloud platforms through a unified control plane. - Touboul said Xeris has the IP to change the landscape of the emerging Guardian Agent market and build governance into the execution layer. - Touboul said the company is working to enforce deterministic control over non-deterministic systems. - Touboul has been credited with key inventions and patents that helped shape modern cybersecurity. - A contact line included in the release listed Xeris AI and a phone number: +972 544227780. - The release also included Touboul’s LinkedIn profile: Shlomo Touboul.

Between the lines: - The leadership shift signals that Xeris wants to be seen not just as an AI security vendor, but as a category builder. - The company is tying its product story to Gartner’s Guardian Agent framing, which could help it gain attention as enterprises look for ways to govern agentic AI. - The emphasis on runtime control reflects a view that traditional security tools may be too late once an agent has already acted.

What’s next: - Xeris is accelerating its effort to define and lead the Guardian Agent market. - The company is likely to use the new CEO-CTO combination to sharpen product execution and market messaging. - Xeris is also signaling that it wants to secure the broader future of agentic AI as adoption expands.

The bottom line: - Xeris is making a leadership and technology bet that runtime governance will become the key security layer for autonomous AI agents.
