SECURE BY DESIGN
Engineered to MOD Secure by Design principles from the first commit — threat-modelled, audit-logged, and built for accreditation, not retrofitted to it.
Software, artificial intelligence and autonomy — engineered in the United Kingdom, for defence and for industry. Built to be trusted with decisions that matter.
Off-the-shelf thinking produces off-the-shelf outcomes. Greyline exists for organisations that need technology made for their problem, on their terms, inside their walls.
Strategic and technical consulting for leaders making irreversible technology decisions — architecture reviews, capability audits, procurement support and independent challenge, delivered by people who build for a living.
Full-stack engineering with production discipline: web platforms, hardened APIs, real-time interfaces and data infrastructure — containerised, observable, and ready for environments where failure is not an option.
Applied artificial intelligence beyond the demo: machine learning, computer vision, autonomous systems and large language models — selected, trained and evaluated against your data, then shipped into systems that survive contact with the real world.
Making your systems work as one: platform integration, legacy modernisation and data flowing cleanly between the tools you already run — including AI capability embedded into existing estates, without ripping out what works.
Engineered to MOD Secure by Design principles from the first commit — threat-modelled, audit-logged, and built for accreditation, not retrofitted to it.
Systems that run disconnected: on-premise inference, offline-first architecture, and deployments that never assume a network — because sometimes there isn't one.
Founded on serving-military engineering experience. We speak the language of the front line and the programme office — and translate between them.
British-built, British-held. Your data, your models and your source stay under your jurisdiction — contractually and architecturally.
Evaluation before enthusiasm. Every model measured, every system tested, every claim falsifiable.
Small teams, senior hands, short loops. Working software in weeks — momentum is a security feature.
The problem, the constraints and what success looks like — understood and agreed in days, before any code is written.
A thin, working, end-to-end version early. Real software in weeks, so decisions are made against evidence, not documents.
Short cycles, weekly demonstrations, senior engineers hands-on. The system grows under production discipline.
Testing and evaluation against the criteria agreed at the start. Every claim measurable, every result repeatable.
Documentation, training and full source code. Your system, your keys — no lock-in.
