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 most valuable features are the antivirus as a whole, the anti-malware, and all of the protection features that scan our enterprise devices."
"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."
"We have not had any issues with bugs or breakdowns."
"Zscaler Internet Access's roaming user feature is most valuable and is much better compared to other secure web gateways."
"In summary, this is a good product and I completely recommend it."
"The solution offers a distributed organization to master and to control all of the endpoints."
"Having a centralized firewall that protects the whole topography is quite awesome when you also have users that are not on the plan because it actually improves visibility of those users."
"Zscaler Internet Access's best feature is the granular policy controls."
"Zscaler is an expensive solution, but it's worth the price."
"For our needs, the cloud-native proxy architecture is a very good solution. We are moving away from on-prem appliances and moving more toward cloud-based solutions. Zscaler is a good fit for our strategy. This architecture helps with cyber threats because we inspect most of the traffic and we can see that a lot of threats are stopped directly in the secure web gateway."
"Zscaler Internet Access's roaming user feature is most valuable and is much better compared to other secure web gateways."
 

Cons

"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 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."
"Every client decided to purchase professional services because deploying Zscaler Internet Access is too complex."
"Zscaler should provide adjacent services, which would be complementary to their current offering that could to be more pragmatic for a customer. For example, if you take Akamai, you get multiple sets of services, all depending on the customer and the strategy and the complexity and the problems. In some areas, they are more varied in terms of coverage."
"There are a few features that are not compatible with the Azure cloud."
"Do not expect to pay for the service and start using it, like Gmail. Zscaler requires a proper implementation to be done to make it successful."
"What could be improved in Zscaler Internet Access is its price. It could be cheaper."
"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."
"I would like to see the ability to choose a pool of IPs for my company, set up rules based on them, and know that those IPs are not used by other companies."
"The tool should improve the predefined dictionaries."
 

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 solution is a little bit expensive. On a scale of one to five, I would rate it as a three."
"If we need any extra features, the price will increase."
"ZIA follows a subscription model pricing and charges you based on the number of users. I would say its price is good."
"It is quite expensive. It does its job, but it is quite expensive for what we need."
"Zscaler is transparent about its pricing model."
"​Be aware that you will need to invest some time and money to adapt your environment for Zscaler (traffic redirection, software deployment, authentication, etc).​"
"Because it's a cloud solution, we pay on a yearly basis. It is affordable and includes tech support and all features."
"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."
