"It used to work fine for all the devices, but it started to slow and become non-responsive. I would have to reload the page two or three times before all the pages loaded. With OpenDNS, I only need to load the page once."
"The interface for administration could be better. They should upgrade the management portal."
"In every cloud service in the world, you have multiple upstream internet providers to create diversity so that if one of your providers fails, your network just continues. In South Africa, there is only one upstream provider, and that's not right. That that's a problem."

"They could provide more time for the onboarding the training of an IT person."

"Zscaler should continue to make the user interface better. They should also improve the backup network and continue to expand it so that it can handle larger numbers of customers."
"One thing that needs to be improved is their presence in China. I'm not sure if that's a Zscaler thing or if it's a problem with all vendors in this space, but it would be nice to have better coverage in China. This concern is a common one for vendors across the board when dealing with the Chinese market."
