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."
"It's a very stable solution."
"The security of Trend Micro Web Security is good."
"I feel that it is a user-friendly product that provides quick response to users."
"The real-time threat detection capability of Trend Micro Web Security has had a positive impact on our security."
"Trend Micro effectively supports our remote workforce by securing our web servers from external threats, particularly browser security."
"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."
"The solution's technical support team is responsive."
"The solution is stable."
 

Cons

"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."
"What could help Trend Micro Web Security in terms of improvement is the addition of a DDoS protection feature. It also needs to be more comprehensive to meet the needs of large-sized companies."
"his legacy version currently lacks WFA, which is a useful tool for managing bandwidth and applying data control limits to specific users. It's especially beneficial for organizations using Android and Azure."
"There is room for improvement in the anti-malware capabilities."
"The cons include it not being implemented in the mid-enterprise segment. For these organizations, it is an additional expense."
"The system should generate reports when an attack has been stopped, contained, or removed."
"There are multiple ways Web Security could improve, such as usability and web access to several programming modes."
"The product's scalability is an area of concern where improvements are required."
"I would like to see better scalability and better performance."
 

Pricing and Cost Advice

"The price of Quad9 is free."
"The license is yearly and user based."
"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."
"We have found this product to be very cost effective. The endpoint product costs roughly $20, and when purchasing the endpoint product, there are multiple other features included."
"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."
"It is pricey. Trend Micro has been in the field for 30 years, so you have to pay a premium amount for that."
"The solution is expensive in terms of deployment."
