A tampered build script infiltrated 6,500+ organizations. Attackers gained persistent access through compromised releases.
Announcing Network visibility for GitHub Actions runners
Your CI pipeline isn’t just a tool—it’s a gateway to your production environment. Every dependency, tool, and script you pull introduces unseen risks. With each build, this invisible attack surface expands, creating critical blind spots that static tools can’t detect.
Attackers are targeting CI systems to infiltrate your systems, even if you're securing your code and endpoints. A single malicious script can compromise sensitive data, expose customers, and damage your reputation.
listen.dev provides unparalleled visibility into what runs during your builds, detecting malicious behaviors that static analysis tools miss.
See every endpoint your builds connect to. Map allowed destinations and block unauthorized egress to prevent data leaks.
Monitor execution flows and system interactions in real time. Catch malicious signals early and reduce mean time to detection (MTTD).
Automatically learn normal runtime behavior for every build and flag anything that deviates.
High-signal alerts are sent directly to your toolchain (e.g., Slack, SIEM) with full context. No noise—just actionable intelligence your team can rely on.
Integrate in minutes—no code changes, no configuration, no overhead.
Purpose-built for modern development teams, stacks and emerging threats.
Powered by eBPF, listen.dev monitors kernel-level execution with minimal overhead.
A single binary deploys seamlessly, with zero configuration.
Lightweight, zero-copy architecture ensures negligible impact on build performance and CI wall times.
Stay ahead of emerging threats. Release with confidence.
“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.”
Isaac Z. Schlueter, NPM, Inc.
“Dynamic analysis of package behavior is huge. It will annihilate a whole class of vulnerabilities”
