Rein Security has secured $25 million in a Series A funding round, bringing its total capital raised to $35 million. The round was co-led by Glilot Capital and Sienna Venture Capital, with participation from Corner Ventures, Atlacle, and RNP Capital Advisors. While the funding total is significant, the more compelling story lies in the company’s reported growth metrics. Since its product launch in January 2026, Rein claims its revenue has grown eightfold and its customer base has increased fivefold.
