Louis Geoffroy - PeerSpot reviewer
President at IDEBUG
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.
Vladimir Alexandrov - PeerSpot reviewer

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

"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."
"It prevents phishing attacks, ransomware attacks, and other threats that can compromise data."
"It's secure and useful from an administrative point of view, with controllable login monitoring and so on."
"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."
"It's a stable solution."
"The most valuable feature is machine learning, which automatically monitors the activity on the machine."
"It's a very stable solution."
"The most valuable feature of Trend Micro Web Security stems from the fact that it is neither a cheap nor an expensive tool."
"Threat protection solution with good stability and scalability. Installation is straightforward. Support for this product is good."
 

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."
"The installation is a little bit complex."
"There is room for improvement in the anti-malware capabilities."
"The system should generate reports when an attack has been stopped, contained, or removed."
"They could improve the platform's ability to control normal traffic and prevent attacks like SQL injection and cross-site scripting."
"There are multiple ways Web Security could improve, such as usability and web access to several programming modes."
"The product should be more secure and stable. It is also not flexible."
"The solution's scalability could be better."
"The cons include it not being implemented in the mid-enterprise segment. For these organizations, it is an additional expense."
 

Pricing and Cost Advice

"The price of Quad9 is free."
"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."
"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."
"It is pricey. Trend Micro has been in the field for 30 years, so you have to pay a premium amount for that."
"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."
"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."
