Advisors from Zscaler, Ivanti, Sapiens, AMINA Bank and Forrester’s Zero Trust research will guide product priorities as AI agents and non-human identities expand the attack surface

PALO ALTO, Calif., Nov. 9, 2026 /PRNewswire/ — Security teams rarely lack tools. What they often lack is connected context: a clear view of how identities, assets, exposures and controls combine into viable attack paths.

Mesh Security, the unified intelligence layer for enterprise security teams, today announced that five cybersecurity leaders have joined its strategic advisory board: Yiannis Vassiliades, CISO in Residence at Zscaler; Jack Nelson, CISO and Deputy General Counsel at Ivanti; Guy Avnor, CISO at Sapiens; Jeff Schiemann, former CISO at AMINA Bank; and Dr. Chase Cunningham, creator of Forrester’s Zero Trust eXtended (ZTX) framework.

Collectively, the advisors bring experience spanning cloud security, enterprise software, insurance technology, regulated banking and Zero Trust strategy. They will provide practitioner perspectives on Mesh’s product priorities, enterprise adoption, and board-level reporting and decision-making as AI agents and non-human identities expand the enterprise attack surface.

“Security tools are effective at the jobs they were designed to do, but attackers move across the boundaries between them,” said Netanel (Neo) Azoulay, CEO and co-founder of Mesh Security. “Yiannis, Jack, Guy, Jeff and Chase bring the operating and strategic perspective to help us show teams which paths are genuinely exploitable — and give security leaders clear evidence for action.”

About Mesh Security

Mesh Security is the unified intelligence layer for enterprise security teams. As organizations scale across cloud, SaaS, on-premises and AI environments, security data fragments across disconnected tools. Mesh connects to the tools a team already runs, without agents, correlates signals across domains and reveals the viable attack paths to an organization’s most critical assets. It also inventories, detects and responds to AI agents, non-human identities and MCP connections.

Built as the world’s first Cybersecurity Mesh Architecture (CSMA) platform, Mesh gives security teams context no single tool can provide. Teams prioritize the exposures that matter, fix them through guided remediation workflows and reduce risk without replacing their existing security stack. Learn more at https://mesh.security.
