We research techniques for the design, implementation and verification of secure and performant real-world computer systems.
We achieve impact by fundamentally changing how software systems are engineered in the real world. Our techniques provide the highest possible degree of assurance—the certainty of mathematical proof—while being cost-competitive with traditional low- to medium-assurance systems.
Our research brings together a unique combination of expertise in operating systems, formal methods and programming languages. Our seL4 microkernel is the most thoroughly verified operating system kernel in the world.
Our work goes beyond research. We show how to build robust, high-performance software stacks for the software development community, and also engage with other organisations to apply our technology to real problems.
Breakthroughs that combine our expertise in operating systems, formal methods and programming languages.
We apply our unique research and engineering experience to solve problems in the real world.
The world's most highly-assured operating system kernel.
Our software and proof repositories, as well as packaged software releases.
Info for prospective students and interns, and courses we teach.
Our research publications and tech reports.
