No maintenance required, free service, but more free features would help
We were using Quad9 to prevent our users from accidentally landing on suspicious websites There's no reporting, but we're hoping that our users have been able to avoid malicious websites. The most valuable feature of Quad9 is that it is a free solution. Quad9 could improve by having any…

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."
"I feel that it is a user-friendly product that provides quick response to users."
"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."
"It's a stable solution."
"The stability of the product is great, there are no bugs or glitches, and it does not crash or freeze."
"Trend Micro effectively supports our remote workforce by securing our web servers from external threats, particularly browser security."
"Trend Micro has a good portfolio for security solutions."
"It's a very stable solution."
"The solution's technical support team is responsive."
 

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 stability of the product is an area of concern where improvements are required."
"The licensing is paid annually. It is a little bit expensive when you compare it to the competition."
"The ease of use depends on the blacklisting of the sites. Some of the authorized sites have been blacklisted, which requires a request to unblock the site."
"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."
"Trend Micro products are quite expensive compared to Kaspersky, Sophos, and McAfee."
"There are multiple ways Web Security could improve, such as usability and web access to several programming modes."
"They could improve the platform's ability to control normal traffic and prevent attacks like SQL injection and cross-site scripting."
"What could help Trend Micro Web Security in terms of improvement is the addition of a DDoS protection feature."
 

Pricing and Cost Advice

"The price of Quad9 is free."
"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."
"We pay for the license on an annual basis."
"The solution is expensive in terms of deployment."
"The license is yearly and user based."
"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."
"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."
