Executive Team

Charles Nasser


Charles Nasser founded Claranet in 1996 and has grown it into an international managed service provider operating in 6 countries. Charles has led the company through a strong period of organic growth as well as several acquisitions from public and private companies.

Charles holds a Masters degrees in Electrical & Electronic Engineering from Imperial College (University of London), a Certified Diploma in Accounting and Finance (ACCA) and a Masters in Finance from the London Business School.
A keen traveller, Charles has visited over 85 countries and participated in several expeditions, including a trek to the geographic North Pole in 2004.

Since 1996, information technology has grown from thousands of users seeking simple dial-up access to millions of consumers and corporate clients who require reliable, high-speed, always-on connectivity. 12 years ago, few business people even had an email address. Today they expect anytime, anywhere access to their email, their company network and even their desktop.

Claranet's vision rests on two criteria which we believe will define the next decade. Information services will continue to play an ever more important role in business. Moreover, the range and diversity of information services will be impossible for businesses to manage in-house.

That is why I've built Claranet into a Managed Services Provider. We develop, support and manage a raft of information technology solutions for our customers, making it possible for them to focus on their business rather than worrying about their technology.

Whether it's a small business looking for basic hosting or connectivity solutions, a large company requiring complex hosting or managed applications, or a multi-site organisation that needs reliable, secure networking, Claranet has already adapted it's infrastructure, services and personnel to offer every technology a company needs - before you realised you needed it.

The Claranet team and I are here to support your every need."
