Stable and scalable solution with a great threat isolation engine
Menlo Security RBI is mainly used to do basic cloud migrationary technologies Menlo Security RBI's best feature is its threat isolation engine. Menlo Security RBI could be more cloud-friendly, and its mobility could be improved. In the next release, I'd like Menlo Security RBI to include a…

Offers good reliability and availability to users
Sometimes, cost is one component that customers complain about, especially if they compare it with some of its competitors. Zscaler's pricing seems to be a bit on the higher side. I think the pricing model is also something that the tool can probably look into to optimize or improve for the customer so that it can be a competitive tool commercially. The solution's technical support needs to be improved, especially by offering a better support structure for different geographical areas.

Quotes from Members

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

Pros

"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."
"Menlo Security RBI's best feature is its threat isolation engine."
"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."
"The solution is stable and reliable."
"Zscaler Internet Access protects using data loss prevention. If you have a CASB exposing your cloud out into the network, then Zscaler Internet Access will go ahead and control that unknown cloud application in the CASB, protecting it. There is also data detection with exact data match. This improves the data coming into your cloud so you are protecting it."
"We don't have to buy equipment to use it. And when our engineers set it up on our side, we just configured a few settings and we were in."
"The VPN is valuable, as the whole technology is very different from a traditional VPN."
"The most valuable feature for me is the ability to see how my network and traffic looks with modules like analytics and insights."
"We enjoy all of the proxy capabilities and the capability to integrate into the SIEM/SOC solution."
"The best thing about Zscaler Internet Access is the website filtering. In the UAE it's quite an important feature because most of the malware comes through the SQL injection and through downloads from websites. Zscaler helps protect against that."
 

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."
"​When you have appliances, SSL inspection is always a headache due to poor performance and/or lack of ciphers implemented. ​"
"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."
"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."
"The solution is expensive. They recently revised the pricing and packaging. Some of our existing customers have been asking for alternate solutions for a lower price."
"They should enhance the audit reporting feature."
"One feature I am missing is the ability to connect automatically to internal monitoring systems."
"The response time and engagement model for technical support could be improved to handle complex outages more efficiently."
"The interface for administration could be better. They should upgrade the management portal."
 

Pricing and Cost Advice

"Menlo Security RBI can be very costly."
"Our monthly fee is around R3000."
"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."
"The pricing is an issue. It is expensive compared to other firewalls on the market."
"It is a few pounds per user per month."
"Because it's a cloud solution, we pay on a yearly basis. It is affordable and includes tech support and all features."
"The tool is moderately priced."
"ZIA follows a subscription model pricing and charges you based on the number of users. I would say its price is good."
"The price of Zscaler Internet Access should improve, it is expensive."
