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.

Consistent web protection has prevented incidents and supports flexible hybrid security models
I would rate Trend Micro Web Security a nine, but not because I have some issues in mind. I have only seen a bit better product. I was also a McAfee partner some time ago, when there was still McAfee. Some features definitely in McAfee were better than what I see in Trend Micro. I cannot tell what Trend Micro could learn from web security products of their competitors because this product has not existed for at least eight years now for McAfee, and I have no experience with other competitors. But relative to my experience and expertise, I should rate it a ten, but still I am a bit cautious because other products also have great features and these features are not covered 100% by Trend Micro. I cannot tell what additional features I would like to see in the next release, but when I see such a feature, it is very compelling. When you get into a new car and this car has something new and great, adaptive suspension, whatever, you just feel a nice feeling and you want this car. That is how I feel. I have not complained that something is missing from Trend Micro product, but I have seen in specific examples some great ideas in competition.

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 has just about everything we need at a good value."
"It's secure and useful from an administrative point of view, with controllable login monitoring and so on."
"Threat protection solution with good stability and scalability. Installation is straightforward. Support for this product is good."
"The security of Trend Micro Web Security is good."
"We have found this product to be very cost effective."
"The stability of the product is great, there are no bugs or glitches, and it does not crash or freeze."
"We find the advanced license for the DLP to be particularly useful with this product."
"It prevents phishing attacks, ransomware attacks, and other threats that can compromise data."
 

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."
"I would like to see better scalability and better performance."
"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."
"There is room for improvement in the anti-malware capabilities."
"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."
"The interface could be improved; we need it to be more user-friendly."
"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."
"The solution's scalability could be better."
 

Pricing and Cost Advice

"The price of Quad9 is free."
"The license is yearly and user based."
"It is pricey. Trend Micro has been in the field for 30 years, so you have to pay a premium amount for that."
"I don't remember the exact pricing, but I think that it is approximately $10.00 per user."
"We pay for the license on an annual basis."
"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."
"The solution is expensive in terms of deployment."
"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."
"I rate the product price a three on a scale of one to ten, where one is cheap, and ten is expensive."
