Shay Sandler

Shay Sandler is co-founder and CEO of Vega, an Israeli cybersecurity company building a federated Security Analytics Mesh that queries security data where it lives instead of dragging it into a centralized SIEM. A former Israeli Unit 8200 officer and early team member at Granulate (acquired by Intel in 2022), Sandler started Vega in early 2024 with Eli Rozen after Intel wound down Granulate. In under two years Vega has raised $185M across three rounds, most recently a $120M Series B led by Accel in December 2025 at a valuation reported between $700M and $800M.
