We performed a comparison between Zscaler Internet Access and Lookout based on our users’ reviews in five categories. After reading all of the collected data, you can find our conclusion below.
Comparison results: Based on the parameters we compared, Zscaler Internet Access comes out ahead of Lookout. While both provide valuable protection of endpoints, Lookout’s potentially lengthy activation process and API functionality leave room for improvement.
"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."
"The solution is stable."
"On the outside, the main differentiation is because Lookout ingest. They have ingested basically all of the apps for the last ten years and all the versions of all the apps, and we have that in a corporate database that allows us to do very large-scale machine learning and analysis on that data set. That's not something that any of the competitors really have the capability to do because they don't have access to the data set. A lot of the apps you can no longer get them because that version of the app is five or six years old, and it just doesn't exist anywhere anymore, except within our infrastructure. So, the ability to have that very rich dataset and learn from that dataset is a real differentiator."
"Zscaler Web Security protects our users in remote locations from internet threats - even if they are not connected to our network."
"In terms of management and visibility, there is a single panel where you can configure the policies for your entire organisation worldwide."
"The most valuable features I found in Zscaler Internet Access are the restriction of users for a particular URL, the security feature related to stopping DDoS, and the VPN."
"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."
"The most valuable feature of Zscaler Internet Access is that it is a consolidated solution, it comes with many features, such as DLP."
"The scanning feature is impressive, because they do not introduce a big latency to the traffic."
"The security is excellent."
"Zscaler covers all the features needed to replace a VPN or proxy solution. They are good. They've been on the market for 15 years now, so they are mature enough."
"Lookout was moving into the SSE space. And so their work on SecureWeb Gateway and SD-WAN is still sort of evolving."
"The stability depends on the service from where you access it. Because sometimes, the place you are in, you have Gateway. You don't have Gateway. The gateway is overutilized. At the end, you need to go through their gateways. And this is the key point here. You have a tracking point. If it's not well orchestrated, and it scales up as you add more to the existing team, you will suffer"
"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."
"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."
"The solution can be improved by advancing some of the newer technologies such as the DLP feature, and adding email security."
"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."
"There are a few features that are not compatible with the Azure cloud."
"Zscaler does not provide dedicated IPs to each customer. Hence, they share a pool of IPs provided by Zscaler. There is a chance of blacklisting these IPs. I also do not like the multi-management portal."
"If they can also integrate with the multi-factor authentication to prompt users to do another, second-factor authentication, that would be ideal."
"There are some performance issues when we add on additional controls."
"Another thing that I would like to see is if Zscaler could have a separate product for direct access. I looked at a private access solution, but I understand there's a separate product that isn't integrated with this."
