Video conferencing apps like Zoom are already pretty secure, given that you are connecting with people you trust. Lot of people are working from home using Zoom application, and right now bandwidth issues are popping up. If you are a business trying to connect with your employees, what you can do is make your own zoom like app specifically for your business. Zoom clones are inbuilt app scripts that can be customized for your business. This would be the most cost-efficient option in the long run and you can make sure that the communication stays within the organization and doesn’t have to depend on any third party. There are companies out there that they provide zoom clone application and they will also help you out with getting it on the Play Store or Apple Store. This will also ensure that you get all the latest updates and features whenever they become available. This method will ensure that your work gets done on time and features like remote access and screen sharing make a really big difference when working from home, or working with companies all over the world. Hope this helps.
