About Us
Built in Israel. Securing the world.
SourceSeal is an Israeli cybersecurity startup on a mission to eliminate software supply chain attacks — using AI, reproducible builds, and blockchain technology.
Our Story
Born from a real problem
The software supply chain is broken. Every day, developers install millions of open-source packages without any way to verify that what they're getting is actually what the author published. Attackers know this — and they exploit it.
SolarWinds. Codecov. xz Utils. ua-parser-js. These aren't hypothetical threats — they're real attacks that compromised thousands of organizations, including government agencies, banks, and critical infrastructure.
We founded SourceSeal because we saw that existing tools only react after the damage is done. CVE scanners catch known vulnerabilities, but they can't detect a compromised build or a hijacked package. We needed something fundamentally different.
SourceSeal rebuilds every package from source, compares it against what's published, runs AI-powered security analysis, and records the result on an immutable blockchain ledger. If something was tampered with — we catch it before it reaches your developers.
What drives us
Our values
Security first
We believe every organization deserves to know exactly what's running in their software. No trust assumptions — only cryptographic proof.
Transparency
Every verification we perform is recorded on an immutable ledger. Our customers don't just take our word for it — they can verify it themselves.
Zero friction
Security tools that slow developers down don't get adopted. SourceSeal works as a transparent proxy — no workflow changes, no learning curve.
Where we are
Based in Israel
Israel is home to the world's most innovative cybersecurity ecosystem. We're building SourceSeal at the intersection of AI, blockchain, and software security — backed by deep expertise in all three.
