The combination of this open-source software, the infrastructure (heiCLOUD) and the configuration (e.g. encryption of data transmission from all users to the server) enables audio and video conferences to be conducted securely. This service is hosted and operated by the URZ in our own IaaS environment/ heiCLOUD and all data transmission is encrypted both to and from the servers. This means that all University employees are not solely dependent upon external video conferencing platforms. The participants also do not need to download any software.
