Identify

Know what’s in your code

The Endor Labs platform uses an unparalleled knowledge base of open source libraries and code relationships to understand your 3rd party dependencies— including open source libraries, AI models, and AI services.

Get an accurate inventory (direct and transitive dependencies) and export SBOM / VEX documents
Correlate inventory to the Endor Labs Vulnerability Database, based on NVD, GHSA, and OSV data along with a manually-annotated, function-level database for vulnerabilities going back to 2018 for 12 languages (and growing)
Detect OWASP Top 10 risks for open source, including CVEs, malicious code, and license risks

Book a Demo

Prioritize

See which vulnerabilities are riskiest

Endor Labs provides several filters to reduce false positives and decide which risks to address first. When used together, customers achieve a 92% reduction in findings, leaving just a handful to fix.

Is it in production code (not test code)?
Is there a fix available?
Is the affected function reachable?
Is there a high probability of exploit (high EPSS)?
How severe could the impact be (CVSS)?

‍

Book a Demo

Remediate

Actually fix vulnerabilities

Give developers the information needed to upgrade dependencies with confidence.

For each version upgrade option, identify whether conflicts with other dependencies will cause problems (like breaking changes)
Compare the number of findings fixed by a single upgrade to the effort it will take to perform the upgrade
Improve mean time to remediation (MTTR) with smarter automatic pull requests and Endor Patches

‍

Not even your developers have this information! They’ll thank you for saying “This upgrade will be easy” or “This other one might take a few sprints because there are breaking changes.”
