OX Security is an Israeli cyber-security company that sells software to secure the software supply chain, the processes by which software is developed and distributed.[1] It was founded by Neatsun Ziv and Lior Arzi, two former managers at Check Point, inside the Team8 company-building incubator in October 2021. According to Globes, the founders reached Team8 through Ziv's acquaintance with Team8 managing partner Amir Zilberstein "from their military service in the IDF's 8200 signals intelligence unit" (Unit 8200).[1] By May 2025 it had raised $94 million.[2]
History
According to Globes, Ziv and Arzi had each worked at Check Point for about a decade, latterly as vice-president for cyber products and director of endpoint cyber security respectively. They began work on OX Security in October 2021 as part of Team8, which made the first investment, and registered it as a company in late July 2022. The seed round was then expanded to $34 million, led by Evolution Equity Partners and Microsoft's venture fund M12, with Rain Capital and Team8; Globes called it "one of the largest ever seed rounds for an Israeli startup".[1]
In May 2025 OX Security completed a $60 million Series B round led by DTCP, with Microsoft, IBM Ventures and Team8 taking part, bringing its total funding to $94 million. It then had 150 employees, 80 of them in Israel, and more than 200 customers, including eToro and SoFi.[2]
Founders and military service
- Neatsun Ziv, co-founder and chief executive: Team8's profile says that "He served in the IDF Cyber Intelligence Unit" (Israel Defense Forces) and that at Check Point his team worked "closely with Interpol, Local CERT and other enforcement agencies".[3] Globes reported that he knew Amir Zilberstein "from their military service in the IDF's 8200 signals intelligence unit" (Unit 8200; Intelligence Corps). He had earlier founded the endpoint-security start-up Vanadium, which he ran from 2003 to 2011.[1]
