Tomer Wetzler

Security researcher & engineer - started my security journey doing research on open source software security, and developing the tools to scan and defend against them. Then, pivoted to cloud apps and identity research in a full research scope, where I researched and created rules to mitigate complex attacks and the use of various attack tools. Now I'm focusing on AI security, where I work to defend AI agents everywhere!
