Yes. InterStar ICP is designed with security in mind. If you need to run a more secure event you [if you’re logged in as the account administrator] can disable audio and/or video and/or text chat in any combination when you’re setting up the event as an administrator. Interpreters and technicians will not be able to reenable them if they do not have administrative access to the account.
The most secure configuration is when participants only use preprogrammed quick messages to communicate however it severely limits the capabilities of the platform.
