Find out in this report how the two Internet Security solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI."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."
"In terms of management and visibility, there is a single panel where you can configure the policies for your entire organisation worldwide."
"The VPN is valuable, as the whole technology is very different from a traditional VPN."
"The initial setup is very straightforward."
"The security is excellent."
"Zscaler covers all the features needed to replace a VPN or proxy solution. They are good. They've been on the market for 15 years now, so they are mature enough."
"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."
"Zscaler Internet Access has helped us reduce the time that we spend managing security policies by about four hours a week. We can use this time to focus on other things, especially the IT team."
"After a proper implementation, the maintenance is very low."
"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."
"Quad9 could improve by having more free features, such as custom DNS filtering."
"Zscaler should continue to make the user interface better. They should also improve the backup network and continue to expand it so that it can handle larger numbers of customers."
"Zscaler Internet Access needs to integrate more ISPs. It is good to have more than three ISPs."
"When you have appliances, SSL inspection is always a headache due to poor performance and/or lack of ciphers implemented. "
"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."
"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."
"Zscaler Internet Access's troubleshooting is very limited, and their textbook logs need to be more informative."
"Currently, the solution's interface is not that user-friendly."
