About
A British boutique
with a clear specialty.
Stacksolver UK Limited is a Brighton-based consultancy. Cyber security is our specialty — and the rest of what we do, from AI engineering to governance, risk and compliance, is built around it.
We were founded on a simple premise: that mid-market UK firms deserve senior expertise delivered without the overhead of a Big 4 engagement. We operate with a lean core team and a curated bench of independent specialists, engaged on a per-project basis. No bench warmers, no junior staff billed at senior rates, no rotating account managers.
What we do
Cyber as our core. Five practices around it.
- Cyber Security — Cyber Essentials Plus, penetration testing, vCISO, incident response.
- AI Engineering — sovereign AI in your perimeter, ethical by default, ISO 42001 ready.
- Areas + AI — Procurement + AI and HR + AI as our anchor practices. AI embedded in the function.
- Governance & Compliance — vCISO retainer, risk register, DPO-as-a-Service, internal audit.
- ISO & Compliance Frameworks — ISO 27001, ISO 42001, ISO 27701, ISO 22301, SOC 2, GDPR.
- NIS2 · DORA · Supply Chain Risk — for UK firms with European operations.
- AI Security & Red Teaming — adversarial testing of LLMs and AI applications.
- Local AI Stack — sovereign deployments on Apple Silicon, NVIDIA or private cloud.
Who we work with
Built for regulated industries.
We focus on five sectors where audit trails, regulatory pressure and data sovereignty are not optional: Technology, Professional Services, Financial Services, Healthcare and Corporate Services.
We serve clients across the United Kingdom, the European Union and the United States. Our clients are typically mid-market organisations — large enough to need real GRC and AI capability, small enough that Big 4 pricing is not viable.
Our standards
We hold ourselves to what we ask of others.
