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
CEO at Chorus
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."
"The EDR feature is very good; it's one of the better features of security and can protect a large percentage of the company."
"Trend Micro Web Security is a great product; it is compatible with anything on the market in my opinion, very competitive and very flexible, and for at least 20 years it has always been top of the line."
"The product's installation phase was easy."
"Overall, I would rate this solution a ten out of ten."
"Trend Micro effectively supports our remote workforce by securing our web servers from external threats, particularly browser security."
"We find the advanced license for the DLP to be particularly useful with this product."
"The real-time threat detection capability of Trend Micro Web Security has had a positive impact on our security."
"We have found this product to be very cost effective."
 

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."
"There are multiple ways Web Security could improve, such as usability and web access to several programming modes."
"There is room for improvement in the anti-malware capabilities."
"The product's scalability is an area of concern where improvements are required."
"They could improve the platform's ability to control normal traffic and prevent attacks like SQL injection and cross-site scripting."
"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."
"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."
 

Pricing and Cost Advice

"The price of Quad9 is free."
"I rate the product price a three on a scale of one to ten, where one is cheap, and ten is expensive."
"The solution is expensive in terms of deployment."
"The license is yearly and user based."
"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."
"It is pricey. Trend Micro has been in the field for 30 years, so you have to pay a premium amount for that."
"We pay for the license on an annual basis."
"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."
