Published on July 29, 2020

This month, the European Union Agency for Cybersecurity, ENISA, has launched a new survey about the security and resilience of Over-The-Top (OTT) communications and collaboration services. The study aims to identify the current risks, mitigation measures and COVID-19 factors affecting OTT services across the European Union. The survey is addressed to industry experts and will remain open until the 14th of August 2020 at 12:00 CET.

The survey is part of a larger ENISA project examining the importance of OTT services under normal and extraordinary circumstances. The feedback from this survey will help the Agency determine key measures and good practices for the provision of secure and resilient OTT services.

About OTT Services

As the COVID-19 pandemic has put a strain on the resilience and continuity of public electronic networks and services, OTT communications services and online collaboration tools have become even more critical for businesses to stay up and running.

The survey only deals with OTT communications services and collaboration services. OTT electronic communications services facilitate real-time interpersonal communication between two or more people via voice, video or messaging – including the sharing of media such as photos or videos. Collaboration services facilitate interpersonal and interactive communication in business/organisational settings with functionalities such as video conferencing, direct file sharing and group collaboration tools.
