Seal Security was co-founded by Itamar Sher (CEO), Lev Pachmanov (CTO), and Alon Navon (CPO). The company employs 35 people across its development centers in Israel and the U.S.
Seal’s platform addresses a growing need in the software industry: the ability to secure software supply chains by automatically detecting and fixing vulnerabilities in open-source components. The company provides ready-to-use patches that secure every layer of the software stack, from code libraries to operating systems.
"Modern development moves faster than ever, and traditional AppSec solutions can't keep up," said Itamar Sher, CEO of Seal Security. "At Seal, we believe the security of the code we build should be accelerated by LLMs, rather than having it exponentially grow our vulnerability backlog. This investment, along with the increased customer demand, validate the demand for our patching-first approach, empowering teams to automatically fix vulnerabilities, maintain compliance, and deliver secure software without altering their workflow."
