The conversation revolves around software supply chain security, which has become a top concern for organizations due to recent high-profile attacks such as SolarWinds and Kaseya. The panel discusses what got them here, why it's a hard problem to solve, and what's being done to address it. They highlight the importance of open-source projects like Sigstore and Cosign, which aim to make software supply chain security more accessible and easier to implement. The industry is moving towards a "secure by default" approach, with vendors expected to provide secure defaults in their tooling, rather than having customers opt-in for additional features. The panel emphasizes the need for collaboration and shared responsibility among organizations to address this issue and make it more manageable for everyone.
