Built from the ground-up to meet these requirements, Ubuntu Core represents a comprehensive ecosystem for large-scale IoT deployments that solves many of the security challenges associated with traditional Linux distribution models — while also empowering developers with unprecedented flexibility and control. This whitepaper from global cybersecurity experts, Rule4, provides an independent, third-party evaluation of Ubuntu Core’s security capabilities. Following a data-driven approach, all aspects received extensive testing to validate the strengths of its cybersecurity controls. Read the report to learn about: * The features and design tenets — such as application sandboxing — that make Ubuntu Core inherently secure out-of-the-box * The case for adopting Ubuntu Core for IoT devices in light of this testing * Rule4’s evaluation methodology and a summary of its results, which included no critical findings [Download report](https://ubuntu.com/engage/ubuntu-core-security-audit) ## Sign up for our newsletter Get the latest Canonical news and updates in your inbox.
