How it works

Rethinking developer security

Open source is under attack

Supply chain attacks on OSS surged 700% while defenses lag behind. Learn more about our team's research and insights on this topic on the listen.dev blog.

"There are a lot of tools that process security advisory data, but listen.dev is the first I've seen that goes a step further, applying behavioral analysis to find issues before they get reported to an advisory database. This is the kind of thing we'd always wanted to do at npm, Inc., but never got around to. It's super exciting to see it come to fruition."
