The reporting functionality could be a bit easier to use. There is a reporting function, but it's quite hard to do any good reporting, from a user-management perspective. For example, if a department manager wants to know how his department is using the web, there is a way to get the data, but it's quite cumbersome to get it and show it well. And that's true for comparing between departments. It's quite hard to get a good report. 

Another issue is that the API documentation could be a bit more up-to-date. They're implementing stuff, but not updating the documentation all the time.

I wish there were a lot less products to learn, because there are a lot. They just keep surprising me with new features, even in the SaaS arena, and they keep improving in every facet. We are Zscaler partners, so I got certified in two platforms, but there is a lot room for improvement. There is just too much training, where they focus a lot on protecting the Internet as everyone is moving to the cloud. I would love for the training to be shortened.

One thing that they could improve is the ability to import rules from other platforms.

I don't know whether it's Zscaler or not, however, sometimes I can't access my time management. I need to wait and try again a few hours later. Typically, if I let some time pass, I can access it again.

From time to time, there's instability in terms of the user experience. I don't know whether it's Zscaler or the time instrument server itself. I don't know the root cause here, that this is the only thing, that causes me issues. Otherwise, I'm quite happy with it.

The solution should do more in regards to handling phishing emails. They maybe should pair with a solution like Palo Alto in order to offer a more holistic view of the security and offer behavioral analytics or endpoint protection, etc., and all from one vendor. Data Lake, for example, is a product that gets the information and gives feedback to the user. There seems to be a high volume of phishing emails that we get, and I'd like to understand what the company is doing to address that. Zscaler seems like it's just a bit too static.

I would like to see more training and video documentation.

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

We did run into some compatibility issues. We just needed to test its configurations on the web portal and that detected the issues.

The solution can be a bit pricey.

Sometimes, support isn't available. 

Zscaler does not have any local data centers. For example, if we have our customers in Czech Republic, in the Czech Republic they don't have their data center, as the local content, in the Czech language. They should do something in the Czech Republic and ensure that the language is accessible. They should have one data center as these people want to see the local content. Everyone wants to see their first language in the available content.

Also, in Brazil, they just have two data centers in São Paulo and they should consider expanding to other data centers.

When you check the logs, you cannot see what policy is allowed. That is one thing that is lacking. If I put someone's account in Zscaler, then it should show which policy it will be applicable for. For example, in Forcepoint we have that feature. This is something that Zscaler needs to add. They just need to put the account of some users and check whether they will be able to access that or not.

They don't have MFA, or multi-factor authentication, for admins.

Zscaler needs to add client-to-client communication. It's always client-to-server communication. The cloud and branch connectors could be improved because we're still dependent on traditional firewalls. They should eliminate this. They should also provide WAN devices should to compete with the SD-WAN solutions also.

Zscaler Internet Access can improve by having more option for filtering policy which is currently only ip based (location policy). The developer need to add more option like identifying DNS and Domains names as well along with ip.

What could be improved in Zscaler Internet Access is its price. It could be cheaper.

There are a few features that are not compatible with the Azure cloud.

It's not fully compatible with our environment because of the way that it is divided into business units. In order to get it working properly, there are some things that we had to put in for enhancements. Otherwise, everything works well.

The price of the solution could be improved. 

Zscaler Internet Access could improve by adding a VPN feature.
