Announcing Network visibility for GitHub Actions runners

Stop malicious code before it hits production

Get complete visibility and control over third-party code executing in your builds. Prevent supply chain attacks and find issues before your users do.

A growing attack surface

Your CI Pipeline Runs Code You Can’t See or Control

Every build pulls in third-party dependencies and workflows. With each update, your attack surface grows—introducing unseen risks into your environment.

Real Attacks & Impact

From CI compromise to widespread breach

Recent incidents have shown how attackers exploit CI environments to inject malicious code, leading to significant breaches. A single script is all it takes – putting sensitive data, customers and reputation at risk.

Compromised build script led to breaches at 6,500+ organizations. Attackers gained persistent access through tampered releases.

A compromised bash script in CI pipelines stole credentials from thousands of companies, remaining undetected for two months.

Dynamic injection through build process enabled widespread crypto theft. Millions affected. Bypassed all static analysis.

Protect your GitHub Actions workflows

Runtime security monitoring for CI/CD

listen.dev provides visibility and control over what executes in your GitHub Actions environment. See behaviors that static tools miss.

Monitor every connection

See every connection your builds make. Map allowed endpoints and block unauthorized egress to prevent data exfiltration.

    Detect & block malicious activity

    Monitor actual runtime execution and system interactions. Reduce MTTD through early detection of malicious signals. Catch attacks that static tools miss.

      Behavioral baselines

      Automatically establish a behavioral baseline for every build. Flag anomalies and stop suspicious patterns as they emerge

        Actionable Alerts in Your Tools

        High-signal alerts delivered directly to your existing toolchain (e.g., Slack, SIEM). Get full context for every detected threat

          Integrate in minutes

          One step in your GitHub Actions workflow

          Dev-time Observability

          A modern approach to secure development

          Runtime monitoring for modern architectures, threats and teams.

          Comprehensive supply chain protection for frontier teams

          Stay ahead of emerging threats. Ship secure products.

          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.
