About Umbriel

Umbriel is a research and engineering company focused on the intersection of artificial intelligence and cybersecurity.

We develop and explore advanced AI technologies for difficult security problems, with a particular focus on software analysis, vulnerability research, autonomous security systems, and the infrastructure required to make modern AI effective in real-world security environments.

Our approach is research-led and engineering-driven. We investigate technically challenging problems, build systems to test new ideas, and turn promising research into practical capabilities.

Artificial intelligence is beginning to change how software can be analysed, tested, and understood. Umbriel exists to push that transition forward — combining deep security expertise with research into large language models, agents, inference, reasoning, and specialised AI systems.

Our goal is to build technologies that materially advance what is possible in cybersecurity.
