Horizon basically protects you're VMware and your Bring Your Own Device (BYOD). BYOD connecting to your network and these can be secured using VMware Horizon.
With COVID there is a very big impact. There is a hybrid kind of workforce model now. People will be able to connect using their own devices. If it is BYOD case, the number of assets is going to increase. It will almost double the number of the secured assets out there. This means that as the asset size grows, there's a lot of traffic. If you talk about the Horizon it is Zero Trust Architecture plus Micro-segmentation. It has to level both into one platform.
You then need to physically test that your endpoints are all secured so that there is no way for somebody connecting from their own device or laptop to accessing the network with any kind of malicious code. You're protected.
