Block Attacks And Only Use Trusted Open-Source Code
Know the risks in  open-source packages before they are used, prevent malicious packages from ever entering your organization and approve the packages that can be used based on criteria that maps to your specific threat model.

Think of Phylum as a Firewall for Open-Source Software Packages
Phylum knows the risks as soon as third-party code is published into npm, PyPI, Nuget, RubyGems, Maven, Crates.io and more, providing a layer of defense between the open-source ecosystem and the tools used to build software.

Early defense with a native developer experience

Deploy Phylum at the earliest stages of your development lifecycle, either in front of artifact repository managers like Artifactory and Sonatype Nexus, or in your CI/CD pipeline.

Proprietary findings, not curated lists
Phylum users benefit from its powerful, automated analysis engine that reports proprietary findings instead of relying on manually curated lists. Our users know more risks, sooner and earlier in the development lifecycle for the strongest software supply chain defense.

Only approved software packages allowed in source code

Easily select the criteria for the open-source software packages allowed to be used in source code. Use our policy library to choose your criteria based on specific indicators, attack types or regulatory guidelines, or create your own custom policy using Open Policy Agent (OPA).

Historical package lookup
Users can look up historical packages at any time, even after they have been removed from the open-source ecosystem, for incident response, governance or policy adherence purposes.

Continuously monitor for software supply chain threats

Get notified when new issues arise or a package displays risky behavior after use.
