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.

It's easy to use and set up, but I've faced performance problems
I have experience with Quad9 and most other filtering solutions. Quad9 was working well initially, but it started slowing, so I switched to OpenDNS. I recently checked Tom's Hardware, an IT review site, and read a review of seven DNS filters. Open DNS was ranked the fastest, and Quad9 was second. Google was on there too, but they said it didn't filter enough.

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."
"Setting up Quad9 is straightforward if you know what you're doing, and it's easy to use overall."
"The most valuable feature of Quad9 is that it is a free solution."
 

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."
"Quad9 could improve by having more free features, such as custom DNS filtering."
"It used to work fine for all the devices, but it started to slow and become non-responsive. I would have to reload the page two or three times before all the pages loaded. With OpenDNS, I only need to load the page once."
 

Pricing and Cost Advice

"Menlo Security RBI can be very costly."
"The price of Quad9 is free."
