Intranet and extranet

We have developed, and continue to support, intranets and extranets for clients including the Cabinet Office (Resilience Direct), Wesleyan Assurance, the Environment Agency and the Metropolitan Police Service.

The skills and services that underpin intranet and extranet applications are inherited from our web application service.

Customer stories: Wesleyan

CDS, EPiServer’s largest UK Premium Partner, provides Wesleyan with technical expertise and ongoing support as it continues to build and develop its intranet, supporting the company’s ambitious growth strategy.

Wesleyan, like all financial services providers, faces the challenges posed by digital transformation. Access to information and knowledge within the organisation and improved ways to communicate across the traditional departmental boundaries are vital to the process. CDS is helping Wesleyan to develop their Intranet to meet these challenges.

Data exchange

CDS designs, implements and supports two-way secure data exchange services. For example, we set up the Highways Agency’s traffic information news service that provides data about road conditions, traffic warnings and roadworks that the media and many individuals rely on.
