Designed for developers.

  • 100% secure pulls

    The same library names, versions, and installation methods engineers use today, without the risk of pulling something malicious.

  • 0 developer workflow changes

    Echo libraries are safe and vulnerability-free without requiring any version changes to your application dependency tree.

  • 99% vulnerability reduction

    Vulnerability fixes are automatically applied to critical and high CVEs from library installations.

Avoid the risk, eliminate the noise

  • Malware prevention

    Libraries are internally sandboxed to effectively detect and prevent malware before it can reach you.

  • Open source health

    By monitoring the health of the upstream project and maintainer, Echo detects and quarantines any drift in the author, behavior, and release cadence.

  • Vulnerability reduction

    Echo ensures your libraries are clean from critical and high vulnerabilities on the same version your application needs.

  • Confidence baked in

    Teams can seamlessly pull from Echo’s trusted and vetted repository where only safe versions are available to begin with.

Security you can prove

  • Audit and compliance readiness

    Echo delivers audit-ready remediation with clear lineage, consistent policy enforcement, and controlled change management.

  • End-to-end supply chain security

    Libraries are built on Echo’s secure infrastructure, signed and attested for verification, and delivered with SBOM
    and VEX.

For the ecosystems you rely on

Secure your application dependencies without changing how you build, test, or deploy.
