In 2014 Opt-4’s Rosemary Smith and Jenny Moseley founded the Data Protection Network. The DPN publishes views, analysis, practical resources and supportive guides aimed both at experts and non-experts. The content is written, developed and edited by data protection & privacy specialists.

In July 2017, the DPN published industry Guidance on the use of Legitimate Interests under the GDPR. The Guidance was made possible by contributions from the DMA, ISBA and representatives of some of the largest organisations in the UK. It was reviewed and warmly welcomed by the UK’s Information Commissioner’s Office and the DPC in Ireland.
