Seal Security Raises $13M to Automate Fixes for Open-Source Security Flaws

The funding round was led by Vertex Israel, with participation from More Investment House, SBI Group, and CCL.

With this latest investment, Seal Security has now raised a total of $20 million since it was founded in 2022.

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 meets a growing need in the software industry by helping secure software supply chains. It does this by automatically finding and fixing security issues in open-source components.

The company offers ready-to-use patches that protect every part 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."
