Louis Geoffroy - PeerSpot reviewer
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.
Bhaskar Rao - PeerSpot reviewer
It offers us a single point of control, but we've had some problems with performance
We use Zscaler as a secure internet proxy. All of the traffic is filtered through it. We have about 3,000 users at the organization.  All internet traffic goes through Zscaler, which protects the organization's IP, which isn't published publicly. Zscaler's cloud services filter and clear all…

Quotes from Members

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

Pros

"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."
"Zscaler excels in security protection and the cloud is always up-to-date. It does not matter if you are a small or big organisation, you will receive the same security quality."
"The solution is stable."
"The most valuable features I found in Zscaler Internet Access are the restriction of users for a particular URL, the security feature related to stopping DDoS, and the VPN."
"For our needs, the cloud-native proxy architecture is a very good solution. We are moving away from on-prem appliances and moving more toward cloud-based solutions. Zscaler is a good fit for our strategy. This architecture helps with cyber threats because we inspect most of the traffic and we can see that a lot of threats are stopped directly in the secure web gateway."
"Zscaler Internet Access's best feature is the granular policy controls."
"The most valuable feature of Zscaler Internet Access is that it is a consolidated solution, it comes with many features, such as DLP."
"The solution replaces multiple vendor technologies with one which makes it worth the cost."
"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

"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."
"Technical support could be better."
"In terms of user experience, it could be better."
"Zscale is providing a proxy IP, and most government sites will block traffic from a proxy. Also, we see some performance issues on the cloud side during DC failover."
"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's technical support needs to be improved, especially by offering a better support structure for different geographical areas."
"They could provide more time for the onboarding the training of an IT person."
"The OS capabilities and WSL support could be improved."
"Do not expect to pay for the service and start using it, like Gmail. Zscaler requires a proper implementation to be done to make it successful."
 

Pricing and Cost Advice

"The price of Quad9 is free."
"Zscaler is transparent about its pricing model."
"Because it's a cloud solution, we pay on a yearly basis. It is affordable and includes tech support and all features."
"The pricing is an issue. It is expensive compared to other firewalls on the market."
"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."
"We have found the solution to be expensive."
"The pricing for Zscaler Internet Access could be made cheaper."
"Our monthly fee is around R3000."
