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

"Menlo Security RBI's best feature is its threat isolation engine."
"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."
"The solution is stable."
"The security is excellent."
"The most valuable feature of the solution is SWG traffic."
"One feature that is valuable to me from an implementation point of view is that it's very easy to implement."
"We enjoy all of the proxy capabilities and the capability to integrate into the SIEM/SOC solution."
"Zscalar Internet Access is for Internet security, like an Internet security gateway. I like how it runs seamlessly in the background with a single sign-on. The controls you can have on devices for Internet security are good, and it doesn't impact speed wherever you're connected. Overall, I think it's very good so far."
"There is no lag in service when accessing the internet."
"The initial setup was straightforward. The biggest thing for us was to build our own policies. The deployment itself was only a few hours."
 

Cons

"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 could be more cloud-friendly, and its mobility could be improved."
"In every cloud service in the world, you have multiple upstream internet providers to create diversity so that if one of your providers fails, your network just continues. In South Africa, there is only one upstream provider, and that's not right. That that's a problem."
"The pricing is an issue. It is expensive if you have all of your users in the same location. It is expensive compared to other firewalls on the market."
"The solution's pricing is on the higher side. It would be better if it could be lower."
"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."
"The response time and engagement model for technical support could be improved to handle complex outages more efficiently."
"The admin console needs improvement as it loads slowly and sometimes takes two to five minutes to open."
"The deployment process of Zscaler Cloud Connector needs to be more user-friendly."
"The price of the solution could be improved."
 

Pricing and Cost Advice

"Menlo Security RBI can be very costly."
"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."
"It is costlier than other solutions."
"Our monthly fee is around R3000."
"It is quite expensive. It does its job, but it is quite expensive for what we need."
"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."
"Roughly, we might spend $70,000 a month on the solution. We don't pay for anything beyond the standard licensing fee."
"The pricing is an issue. It is expensive compared to other firewalls on the market."
"The pricing for Zscaler Internet Access could be made cheaper."
