About us.
Security and compliance made straightforward, not stressful.
Our mission
At CWSI, we help organisations embrace new technologies with confidence. We’re a team of specialists who make security and compliance straightforward, not stressful. Across the UK, Ireland, the Netherlands, Belgium and Luxembourg, our people bring deep expertise, practical insight to help move your business forward securely.
We believe progress and protection can go hand in hand. That’s why we focus on long-term partnership, standing beside our clients to help them reduce risk, simplify complexity, and stay resilient in a fast-changing world.
Our story
CWSI began in Dublin in 2010, when the first iPads landed in offices and few IT teams knew how to secure them. Our founders saw an opportunity to help businesses embrace new technology safely.
From those early days in enterprise mobility, we’ve grown into a leading Microsoft-focused security and compliance partner. Our journey has been steady and deliberate, one trusted relationship at a time.
Our Microsoft partnership
As a long-standing Microsoft partner and proud member of the Microsoft Intelligent Security Association, we’re trusted to deliver secure, compliant environments built on Microsoft technology. Winning Compliance Partner of the Year in 2024, and twice-named Microsoft Security Partner of the Year, our team combines technical depth with practical know-how to keep organisations confident in their Microsoft environments.
