Harlequin CDIS is an IT Security and IT Manged Services Company

With the threat of cyber-attacks and data breaches becoming so prolific, it is unfortunately no longer a case of IF you will be affected but WHEN.

Harlequin CDIS provide IT Security and IT Managed Services to many organisations, from SME to large financial institutions in UK, Europe and United States, through our integrity and commitment to delivering “right first time” solutions.

With the General Data Protection Regulation (GDPR) in place from May 2018, data security is one of the key areas with which organisations must comply. Harlequin CDIS has developed Cyber Hygiene solutions to help with GDPR compliance as well as assisting in obtaining accreditations such as ISO27001, CyberEssentials and CyberEssentials Plus.

With our IT Security and IT Managed Services, Harlequin CDIS is able to offer its customers not only data security compliancy but efficient and stable platforms on which to base their business.

Markets & Business Sectors






“… Harlequin CDIS look after our IT requirements for 2 sites (Maidstone & Rochester) where we have around 70 employees.

In addition to this they work with our USA parent company as our infrastructure sits within our USA IT operation / domain.

They work very hard to make sure we are happy & they never mind us chasing if we need something doing urgently.

They are both professional and polite in all the dealings and we haven’t had a problem they can’t solve.

Another important point to mention is they don’t try and charge for every additional item out of the contract agreement.

They are very fair and reasonable…”
