Plain English first
We never lead with jargon. If a recommendation can't be explained simply, it isn't finished.
About us
Cyber risk advice built for small businesses
Thornwall Group helps small businesses understand, reduce, and manage cyber risk — without confusing jargon or enterprise-level costs.
Who we are
Thornwall Group is a UK-based cyber risk and business resilience consultancy for small businesses. We help owners and managers identify practical security weaknesses, understand their risk exposure, and take clear steps to protect their systems, staff, data, and customers.
We focus on simple, practical outcomes: what is risky, why it matters, what to fix first, and how to keep improving. Our reports are written for business owners, managers, and non-technical teams — while staying structured enough for technical follow-up where needed.
What we believe
- Good security should be understandable.
- Small businesses deserve practical help, not fear.
- Most risk can be reduced with a few clear steps.
- Honest advice beats exaggerated promises.
Our approach
A trusted advisor, not a technical vendor
We promise clarity, prioritisation, and practical improvement — never fear-based selling or claims to stop every attack.
Continuity-focused
Our goal is keeping your business running — protecting trust, data, customers, and your day-to-day operations.
Compliance-ready
We help you cover GDPR and data-protection basics so you're better prepared for customers, insurers, and audits.
