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

"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."
"The solution is stable."
"It prevents phishing attacks, ransomware attacks, and other threats that can compromise data."
"The solution's scalability is good and we have more than 90 users for it."
"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."
"Trend Micro has a centralized mechanism where we can control and monitor all system protections. It includes detecting any wireless problems, which will be displayed on our portal. We plan to investigate the issues with those systems internally."
"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."
 

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."
"There are multiple ways Web Security could improve, such as usability and web access to several programming modes."
"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 stability of the product is an area of concern where improvements are required."
"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."
"Setup isn't very straightforward. You must have a certified technical engineer."
"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."
"They could improve the platform's ability to control normal traffic and prevent attacks like SQL injection and cross-site scripting."
"I would like to see better scalability and better performance."
 

Pricing and Cost Advice

"The price of Quad9 is free."
"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 license is yearly and user based."
"We pay for the license on an annual basis."
"The solution is expensive in terms of deployment."
"I don't remember the exact pricing, but I think that it is approximately $10.00 per user."
"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 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."
