The CI/CD Attack Surface

Poisoning a build pipeline is the most efficient way to compromise thousands of customers at once. Attackers target GitHub Actions runners to steal secrets from environment variables or to inject malicious code into the final artifact.

Run-Time Pipeline Protection

1-SEC can run side-car style inside your CI/CD environment.

Exfiltration Monitoring

1-SEC monitors outbound network calls from the runner. If a build script suddenly tries to send data to an unrecognized external IP—a classic sign of a stolen secret—1-SEC kills the process and fails the build.

Scanning Build Artifacts

Use `1sec scan` as the final step in your pipeline to check the resulting binary or container image for known malware signatures or unauthorized structural changes.
