Networking and after-parties

Open Source Summit is famous for its social program: the all-attendee reception, the “Tux Trek,” speed networking, and community BoF sessions turn the hallway track into a genuine highlight.

Where container security fits into the conversation

Open source software is the raw material of nearly every container image, and the summit’s supply chain track exists because that raw material carries risk — unpatched dependencies, unsigned artifacts, and images with no verifiable provenance.

Echo ships images that are CVE-free, FIPS-validated, and hardened against DISA STIG requirements, with full SBOM transparency in SPDX and CycloneDX and signed provenance via cosign and sigstore — exactly the supply chain hygiene the OpenSSF community champions on stage.
