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.
Durai  Singh - PeerSpot reviewer
Provides comprehensive protection for enterprises
The cons include it not being implemented in the mid-enterprise segment. For these organizations, it is an additional expense. Even companies with multi-tenant, multi-cloud, and multi-geolocation environments are not using this WAF solution because it is an investment. They already have endpoint protection, EDR, firewalls, and authentication. Spending on WAF is an extra investment for them. This is one reason mid-enterprise segments hesitate to adopt it.

Quotes from Members

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

Pros

"The most valuable feature of Quad9 is that it is a free solution."
"Setting up Quad9 is straightforward if you know what you're doing, and it's easy to use overall."
"The solution is stable."
"The solution's technical support team is responsive."
"The most valuable feature of Trend Micro Web Security stems from the fact that it is neither a cheap nor an expensive tool."
"Currently, many applications are hosted on the web. They are hosted in multiple clouds and tenants. Organizations with different geolocations and users require a very secure WAF solution. For enterprise companies, it is essential to secure their networks and applications."
"Trend Micro effectively supports our remote workforce by securing our web servers from external threats, particularly browser security."
"It's a very stable solution."
"The most valuable feature is machine learning, which automatically monitors the activity on the machine."
"The security of Trend Micro Web Security is good."
 

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."
"The costs are a bit high in terms of licensing."
"The price of Trend Micro Web Security is the only area of concern where improvements are required. From an improvement perspective, the product should be made available to users at a cheaper rate."
"This solution has a lot of restrictions on what non-administrator users can do, including generating comparative code. We would like to see this changed as the product is developed."
"The cons include it not being implemented in the mid-enterprise segment. For these organizations, it is an additional expense."
"The stability of the product is an area of concern where improvements are required."
"Setup isn't very straightforward. You must have a certified technical engineer."
"The installation is a little bit complex."
"The system should generate reports when an attack has been stopped, contained, or removed."
 

Pricing and Cost Advice

"The price of Quad9 is free."
"The license is yearly and user based."
"I rate the product's price a five on a scale of one to ten, where one is low price and ten is high price."
"We pay for the license on an annual basis."
"I don't remember the exact pricing, but I think that it is approximately $10.00 per user."
"There's annual and monthly options for the license. When you're on the managed services option, it's monthly. They're also setting up an option via AWS where there will be a monthly option via the AWS shopfront."
"The solution is expensive in terms of deployment."
"I rate the product price a three on a scale of one to ten, where one is cheap, and ten is expensive."
"It is pricey. Trend Micro has been in the field for 30 years, so you have to pay a premium amount for that."
