We are a Digital and Cyber Security Service provider that believe results come from a well-executed and business-integrated approach, applying our skills and expertise with risk intelligence.

A higher quality IT security management service

  • We set out with one mission: to offer significantly higher quality IT security management services to our clients. More flexible and responsive, with a greater level of practical expertise. Today our highly-professional IT security management specialists are still going above and beyond to deliver precisely that.

Managing IT security infrastructure for leading companies worldwide

  • In the last 13 years we’ve helped scores of the world’s top brands plan, structure, deploy, test and manage robust, reliable security solutions. We currently manage over 1,000 security devices for more than 80 customers across 5 continents. Our clients span multiple sectors including banking, telecoms, retail, government, insurance and leisure.

Creating long-term relationships

  • We pride ourselves on building long-term relationships with our customers. For their part, our clients tell us that it’s our quality, flexibility and specialist skills that set us aside from the mainstream.

Managing IT security is all we do, every day, which keeps our knowledge fresh and our skills honed.
