Who we are

A British consultancy with a clear specialty.

Fox&Stack is a Brighton-based consultancy serving organisations across the United Kingdom, Europe and the United States. Cyber security is our specialty — and the rest of what we do, from AI engineering to governance and compliance, is built around it.

Our work spans Cyber Essentials Plus and penetration testing, AI engineering with a strong focus on Procurement + AI and HR + AI, ISO 27001 and ISO 42001 implementation, and NIS2, DORA and supply chain risk programmes for firms with European exposure.

We work primarily with regulated industries: financial services, healthcare, professional services, technology and corporate services, where audit trails and data sovereignty are not optional.

What we do

Cyber as our core, with four practices around it.

01
Our specialty
