Decreased our security alerts without impacting employees' work
I can't say that there is one specific feature that is most valuable. It's the overall platform that is well-suited to our needs. It's something that is different from a lot of other products or platforms in the marketplace. It provides a single console for security policy and management. That is somewhat important because we used to have other products where you would have to log in to individual appliances, devices, or clusters. Having one spot to log in to or one area to go to for doing different tasks and viewing data sources, just makes it easier from a user perspective. Also, the fact that it's invisible to our end-users and doesn't affect their work is very important. Most companies don't want to have added friction or impact on their users. In addition, the combination of user-friendliness for admins, and security for the organization, works well. As a cloud-hosted solution, it provides ease of use.

Cloud security has transformed remote access and now supports zero trust for all users
The best features Zscaler Internet Access offers are Secure Web Gateway, URL filtering, SSL inspections, and policy-based access control. I find myself relying on Secure Web Gateway, URL filtering, SSL inspection, and policy-based access control the most because these are the main and top-most features I use regularly. Zscaler Internet Access has all of these types of features for securing all internet access and web inspections, allowing me to control all traffic through these features. Zscaler Internet Access features include a Secure Web Gateway for URL filtering, file type control, and inline SSL inspections. The second feature is a cloud firewall with Layer 3 to Layer 7 filtering control and stateful inspections. No hardware inspection or hardware firewall is required. I can also perform segmentations by users, location, and application. There is a cloud CASB solution available as well. Additionally, there is an advanced threat protection feature with signature-based behavioral detections, inline IPS, and zero-day threat protections. The cloud sandboxing solution scans unknown files and provides machine learning-based verdicts to prevent zero-day malware delivery in my environment. There is also a DNS security feature that provides DNS tunneling detections, malicious domain controls, and faster threat containment at the DNS layer. The data protection feature includes inline DLP and CASB-style cloud app control, data sovereignty enforcement, and browser isolation, which executes risky sites in isolated cloud browsers and prevents endpoint compromises. Zscaler Internet Access has positively impacted my organization by reducing the dependency on on-premises hardware and improving security posture, enabling faster user onboarding, and providing better performance for remote users. It has resulted in a drop in security incidents related to web threats and improved visibility into user activity. An area for improvement includes fine-grained troubleshooting tools, better policy simulations, and optimizations around initial configuration complexity.

Quotes from Members

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

Pros

"Menlo Security RBI's best feature is its threat isolation engine."
"In addition, the combination of user-friendliness for admins, and security for the organization, works well."
"Menlo Security RBI has a very good record on stability."
"I can't say that there is one specific feature that is most valuable. It's the overall platform that is well-suited to our needs. It's something that is different from a lot of other products or platforms in the marketplace."
"It securely transfers internet connectivity seamlessly, without any problems or issues."
"Since this is a cloud based product, we don't have to bother about the hardware or physical status and space."
"The solution offers a distributed organization to master and to control all of the endpoints."
"Zscaler offers a centralized DLP solution for web, endpoint, and email."
"The solution replaces multiple vendor technologies with one which makes it worth the cost."
"Zscaler, on the other hand, is more stable and also more secure."
"This solution helps you establish a secure connection from your laptop to the closest Zscaler point of presence, so you have protection anywhere in the world."
"One on the main benefits is protection all time from anywhere."
 

Cons

"Menlo Security RBI could be more cloud-friendly, and its mobility could be improved."
"There are several features, such as supporting web technologies, that the company is working on implementing in the platform. There are a lot of backend web technologies in use on various websites, for example, two-way audio/video and WebGL, for which support may not be fully implemented in the product."
"Menlo Security RBI can be very costly."
"Currently, the solution's interface is not that user-friendly."
"In terms of usage, here in the GCC, it's still growing a growing market, so the combination of DLP, data leak prevention, to a certain extent is fine. But what it requires is user-based access or role-based access. The solution needs to grow into that, which definitely takes time. There's not an easy way to integrate it, when you have a cloud-based solution."
"Sometimes, support isn't available."
"We did hit a problem a while back where they didn't scale properly and we had some major issues."
"We'd like for them to include some sort of antivirus tool."
"They could provide more time for the onboarding the training of an IT person."
"With the pricing structure that they currently have, it is only for big customers."
"The admin console needs improvement as it loads slowly and sometimes takes two to five minutes to open."
 

Pricing and Cost Advice

"Menlo Security RBI can be very costly."
"​Be aware that you will need to invest some time and money to adapt your environment for Zscaler (traffic redirection, software deployment, authentication, etc).​"
"The tool is moderately priced."
"Because it's a cloud solution, we pay on a yearly basis. It is affordable and includes tech support and all features."
"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."
"We have found the solution to be expensive."
"If we need any extra features, the price will increase."
"Roughly, we might spend $70,000 a month on the solution. We don't pay for anything beyond the standard licensing fee."
"The price of Zscaler Internet Access should improve, it is expensive."
