Enhanced mobile security with visibility into app and website usage, but installation challenges remain
We use Lookout for mobile devices, such as phones It has reduced our risk around mobile devices. I like the security features and being able to see what apps and websites people are using. There is nothing we have come across that we've desired. We have been using Lookout for one year. The…

User access management and threat prevention are enhanced with user-friendly controls
The best features Zscaler Internet Access offers include application control, tenant segregation, and PoP center regions which have low availability zones. The internet access is very successful and bandwidth speed is excellent. It also has application-based control, URL-based control, and SSL inspection capabilities, which are very useful. Additionally, the in-depth CASB segregation is very beneficial to us. One unique feature I found helpful is the tenant level restrictions, which we use to only access our organization's tenant level mail IDs, drives, and specific tenant level access while restricting public access. Zscaler Internet Access has positively impacted our organization as we have noticed substantial outputs and income. It has improved our security environment control and endpoint protection. It prevents numerous web attacks through its AI/ML incorporated capability which identifies malware, threats, and viruses. It has a toggle button to enable features entirely at the tenant level for all users onboarded into Zscaler Internet Access, resulting in much better outcomes.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The protection offered by the product is the most valuable feature. It detects vulnerabilities or traps on our users' phones and then prompts them to clean up their devices. Tools we used previously would only discover, which required us to gather information on the backend, so Lookout is a welcome upgrade."
"The most valuable features are the antivirus as a whole, the anti-malware, and all of the protection features that scan our enterprise devices."
"We have not had any issues with bugs or breakdowns."
"The scanning feature is impressive, because they do not introduce a big latency to the traffic."
"The most valuable feature of Zscaler Internet Access is that it is a consolidated solution, it comes with many features, such as DLP."
"The solution replaces multiple vendor technologies with one which makes it worth the cost."
"It is easy to set up the solution."
"One feature that is valuable to me from an implementation point of view is that it's very easy to implement."
"The data loss prevention feature is the most valuable. It stops our users from inadvertently leaking our customers' data to the Internet or anywhere else it shouldn't go."
"Stability-wise, I rate the solution a nine and a half out of ten...The setup phase was easy."
"I like the granularity of the control of all the traffic, including SSL inspection. I also like the fact that the user interface is intuitive. The latencies with Zscaler are minimal compared to those of any other competitor. Other competitors do not really have the global scale that Zscaler has and cannot promise low latencies."
 

Cons

"The initial setup requires a little bit of experience with configuration."
"We just submitted an enhancement request reflecting the main area we want to see improvement in; the APIs. Currently, we're able to build dashboards, but it's somewhat backward because we use our MDM API to create them. Lookout should provide API to customers so we can query our data and use it in our cloud, and this is the only outstanding area for improvement with the product right now."
"From the analysis that we've done, they do seem to be maybe a step behind in trying to enter the market with a new solution. But when they do pick up, they do come out with some good products."
"The performance needs improvement. Some areas create performance issues and, depending on the use cases, require reconfiguration to perform again."
"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."
"We'd like for them to include some sort of antivirus tool."
"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."
"The response time and engagement model for technical support could be improved to handle complex outages more efficiently."
"One thing that they could improve is the ability to import rules from other platforms."
"If they can also integrate with the multi-factor authentication to prompt users to do another, second-factor authentication, that would be ideal."
"In terms of user experience, it could be better."
 

Pricing and Cost Advice

"Lookout is definitely on the lower end when it comes to price point and that seems to be the only differentiator. The technology is in place in this space and it's really about who is coming in at the better price point now."
"The pricing is fair; it's comparable to our previous solution, and we carried out multiple POCs and POVs (proof of value). The product is worth the money we pay for it."
"The pricing is fair based on its competitive market."
"Zscaler is an expensive solution, but it's worth the price. Their services are unmatched by competitors. Some may come with half the features that Zscaler can offer and be much cheaper. However, they do not have the global coverage that Zscaler has, and they will not provide the same low latencies and the same speeds that Zscaler can."
"ZIA follows a subscription model pricing and charges you based on the number of users. I would say its price is good."
"Because it's a cloud solution, we pay on a yearly basis. It is affordable and includes tech support and all features."
"If we need any extra features, the price will increase."
"Licenses are available on a per-host basis. Some features like sandboxing require an additional fee, but most standard features are included in the license."
"Price-wise, the tool is reasonable compared to the other products in the market but it is not a very low-priced tool. The solution does provide value for money."
"Our monthly fee is around R3000."
