Flow Security was an Israeli cyber-security start-up based in Tel Aviv that developed software to find, map and protect companies' data in cloud systems "at rest, in use, and in motion".[1] It was founded in 2021 by Jonathan Roizin and Rom Ashkenazi.[2] Roizin's "cybersecurity foundation was built as an officer in the IDF's elite 8200 intelligence unit" (Unit 8200), according to the founder directory of the Silicon Valley–Israel programme SV101.[1] The US security company CrowdStrike agreed to buy it in March 2024, for about $200 million according to press estimates.[3]
History
In August 2022 Flow Security raised $10 million in seed funding led by Amiti. It then employed 23 people, most of them at its research centre in Tel Aviv.[2] On 6 March 2024 CrowdStrike announced that it would buy the company. No price was disclosed, but Globes reported estimates of $200 million and said that the company's 30 or so employees would join CrowdStrike.[3] Ctech also put the deal at $200 million and said that Flow had raised $13 million in total.[4] Globes gave the total as $15 million in two seed rounds, and listed among those who would profit from the sale the founders, Ben Rabinowitz and Yafit Schwartz's Amiti Ventures, Amdocs Ventures, Singtel, and the angel investors Udi Mokady, former chief executive of CyberArk, and Slavik Markovich, former chief executive of Demisto.[3] Its technology was integrated into CrowdStrike's Falcon Cloud Security platform, where Roizin became a senior director of product management.[1]
