CHL’s data protection and information security courses can be delivered online, on site or a combination of both. Our current courses include:

GDPR – In a nutshell – EU General Data Protection Regulation (GDPR) – key awareness topics for small business

Information security awareness – This one-day, on-site, instructor-led, non-technical information security awareness course, avoids (almost all) jargon to outline key small business security threats and give you actionable solutions.


Data protection and information security training, education and development courses

Every client requirement is unique. But, they all start with a conversation. About your needs.

Adding value depends heavily upon soft skills, i.e. communication, friendliness and empathy. Naturally, we adopt best practice skills and techniques. But, we’re not pedalling ‘cookie cutter’ solutions.

If you want an experienced and knowledgeable team who will focus on your desired outcomes rather than process, why not talk with us? Think experience, solutions, outcomes, practical, pragmatic, flexible, innovative …

To begin that conversation, email, call us on +44 (0)1905 821786 or our contact form.
