Labrys - deploying air-gapped Matrix
Air-gapped Matrix is usually treated as a deployment question. For us, it is the architecture.
Axiom is Labrys’ operational platform, built for military clients and the most hostile threat models you can name: encrypted communications, verified media, shared mapping and live location. Underneath it, Matrix is NOT just the messenger. It is the transport. Homeservers, rooms and events carry the rest of the system, including across networks that never touch the public internet.
This talk covers what had to move inside the boundary, why using Matrix as a transport is particularly useful in isolated networks, and what we learned from taking a live platform off the internet.
Dan is a cryptographer and systems architect who has spent 15 years building high-security platforms. He started in offensive security, designing rootkit malware from a young age and developing low-level systems. He later went on to lead secure mobile and platform architecture for organisations including Visa, BBC News, NatWest, Deloitte Digital and multiple challenger banks.
He is now CTO at Labrys, where he owns the architecture behind Axiom and the Obsidian stack that runs it.
Luke co-founded Labrys after serving as a British Army officer and linguistics specialist, with operational experience across the UK Ministry of Defence, FCDO and allied partners.
He built the company around a problem he had seen first-hand: official systems that cannot keep up in the field, causing people to fall back on insecure tools. At Labrys, he leads the operational and commercial side of Axiom, taking a military-grade platform from concept into live defence, government and high-risk deployments.
