Built for complicated stacks

The scanners were built for someone else's stack.

You tried them, and they didn't run on your builds. You're not the problem. Kusari builds the dependency graph from your actual builds, so it runs on the stack you have.

Monorepos

One repository, several languages, and a build graph that no single lockfile describes.

Mixed languages

Services, research code, and tooling written in far more than npm and Go.

Several source control platforms

Code spread across GitHub, GitLab, and Bitbucket, with no one place to search it.

Acquired and migrating estates

Stacks inherited in acquisitions and half-finished cloud migrations, all still shipping.

Kusari speaks one language: the SBOM. Supporting a new build system means writing an SBOM generator for it with Waybill, a much narrower job than rebuilding the product. A regulated SaaS company in a FedRAMP environment was running on Kusari in three weeks, displacing GitHub Advanced Security.

The founders automated stacks like these at Bridgewater and Citi.

The clock moved

Your process was built for a slower threat.

AI writes more code, pulls in more dependencies, and finds exploitable bugs faster than the people patching them.

The answer before the board asks.

One paragraph to forward when the question comes from upstairs.

Kusari gives us a verified map of every dependency in our software, including the custom build setups our current tools can't read. When a new attack drops, we can say within the hour whether we're exposed and where. Every finding comes with evidence our auditors accept, in open formats like CycloneDX, SPDX, and OpenVEX. The founders ran software security at Bridgewater and Citi, then wrote the standards behind the SBOM and provenance requirements our auditors now ask about.

From evidence to merge

Verify, prioritize, fix.

Security Assistant sits on top of all three. Ask your estate a question, get a traceable answer grounded in the verified graph.

Prevent and prove

Set the policy. Keep the receipts.

Mike Lieberman maintains SLSA, and the team built GUAC with Google.

Prevention as policy

Set the policy once: unsigned code doesn't merge and unattested artifacts don't deploy. SLSA shows your auditor it's working.

Signed commits Attested artifacts SLSA provenance
Evidence in open formats

Every finding ships with evidence in open formats your auditor can use.

How it works

One graph, verified at the source.

  • Built from sourceEvery component tracked on the way in, never reverse-engineered.
  • One source of truthRepos, images, and pipelines in one graph.
  • Open and explainableThe Kusari Score shows its reasoning.

Built by the team that maintains SLSA and built GUAC with Google.

The reachability layer changed the conversation entirely — we went from triaging noise to fixing what was actually exposed. Kusari built our dependency graph on the first day and cut our actionable vulnerability queue by 89%.

FAQ

How the Platform actually works.

What does Kusari Platform do?

Kusari Platform maps your software supply chain into one dependency graph, ranks what's actually exploitable, traces a package across your estate, and plans verified fixes.

How is this different from my scanner?

A scanner inspects the finished artifact and assumes it's trustworthy. Kusari checks that artifact against the source that produced it, then runs reachability on that verified foundation.

A critical vulnerability just dropped. How fast can I answer?

Within the hour. The dependency picture is already current, so finding every affected app, service, and pipeline is a single query.

Do I have to replace my existing tools?

No. A 6,000-seat health insurer kept its full SAST, SCA, container, and dependency stack, added Kusari underneath, and cut vulnerability noise by 90%.

How is the ranking defensible to an auditor?

The Kusari Score methodology is open and explainable. Every ranking shows the reasoning and the path, so your team can defend the decision with its own evidence.
