Palo Alto – November 10, 2026 -- Mesh Security has appointed five cybersecurity leaders from Zscaler, Ivanti, Sapiens, AMINA Bank and the Zero Trust research community to its strategic advisory board, as AI agents and non-human identities widen the enterprise attack surface.
Advisors will steer product priorities and board-level reporting
The five will give practitioner input on Mesh's product priorities, enterprise adoption, and board-level reporting and decision-making. Their combined experience spans cloud security, enterprise software, insurance technology, regulated banking and Zero Trust strategy.
Mesh CEO and co-founder Netanel (Neo) Azoulay said "attackers move across the boundaries between" security tools, and that the advisors will help Mesh show teams which attack paths are genuinely exploitable.

Mesh correlates signals across tools without agents
