Echo builds CVE-free container images for cloud-native infrastructure. The company addresses the challenge that traditional vulnerability scanning and remediation tools scale slower than the rate at which vulnerabilities accumulate in cloud environments. Rather than detecting and patching vulnerabilities after deployment, Echo takes a preventative approach by building thousands of AI-powered container images from the ground up that are free of Common Vulnerabilities and Exposures (CVEs). The company was founded by Eilon Elhadad (CEO) and Eylam Milner (CTO), who previously co-founded Argon, a software supply chain security company that was acquired by Aqua Security. The team includes engineers who developed Microsoft Defender's container engine and Trivy Enterprise, bringing experience in container and supply chain security. Echo's solution allows organizations to pull pre-built container images that scan clean immediately, eliminating the need for vulnerability remediation workflows. This approach targets companies running cloud-native infrastructure who need to secure their containerized applications without disrupting developer workflows. The company is backed by venture capital firms and security industry executives from organizations including Palo Alto Networks, Okta, Aqua Security, and Axonius.
