You can anonymise an entire event (all the participant data or part of it) in the Compliance Center. 

The Compliance Center is available only to the admin users in your organisation and it can be found in the Data Protection section in Lyyti. The features available are dependent on your Lyyti license -- here you'll find more information about issues regarding data protection: https://www.lyyti.com/data-protection
