Welcome to Trustworthy Systems!

We are the Trustworthy Systems group. We use rigorous formal methods to develop trustworthy software systems—systems that come with provable security, safety and reliability guarantees.

We are 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 vision statement is:

We aim to change the world by making software truly trustworthy.
We have made verified software a reality.
We’re now working on creating a societal shift  towards mainstream adoption.


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 build robust software stacks for the software development community, and also engage with other organisations to apply our technology to real problems.
