Global load balancing has ensured continuous availability and optimized user response times
While F5 BIG-IP DNS is a very powerful solution, some improvements could enhance the overall experience. For example, the user interface could be more modern and simplified. The reporting and analytics features can be improved. Simplified deployment for cloud-native environments could be improved. Overall, F5 BIG-IP DNS is a robust and reliable solution for global traffic management and application availability. With its advanced traffic steering capability, we are definitely getting great benefits from that. However, the user interface is the major thing I think can be improved. The cost also can be reduced. Those are the two or three points that need to be improved. There is some scope for improvement, including the user interface and pricing. That is why I gave it a nine.

Offers reasonable pricing and solid scalability in the enterprise context
In my limited experience with Webroot, it has shown good scalability, particularly in the enterprise context. When it comes to Webroot DNS, I find it to be a nice solution but prefer a more comprehensive approach. I lean towards XDR vendors that can integrate DNS protection into a unified dashboard, especially as traditional anti-malware solutions like Webroot face challenges with evolving threat actors. Currently, I have around 60,000 Webroot users for anti-malware, but for DNS protection, it is a fraction—about one or two percent—since some clients opt for other solutions. Traditional anti-malware technology is becoming less effective against sophisticated threats.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The management is very easy."
"It's very stable."
"F5 BIG-IP DNS is a stable solution."
"BIG-IP DNS effectively handled a traffic surge. For example, we have application forms replicated across our DCs. If our primary application becomes unavailable, BIG-IP automatically fails over to a client-unaware secondary application."
"The main features valued in F5 BIG-IP include high availability, scalability, and protection of applications from attacks."
"The GTM feature is very good, It's very useful, especially if we have multiple data centers. If we want to load balance traffic from multiple data centers, the GTM feature is very useful."
"In summary, this is a good product and I recommend it."
"F5 BIG-IP DNS is useful, depending on how you use it."
"When compared with other products, Webroot DNS Protection is the best to secure the end users."
"DNS protection is valuable."
"Almost everyone who uses it is happy about the product. I don't get any types of complaints from my clients."
"I would recommend Webroot; it is a very good solution and a solid solution that keeps our computers protected."
"Webroot excels in DNS protection, particularly in blocking malicious sites and phishing."
"The installation is easy and doesn't take long. The program speedy and doesn't crash. It doesn't consume computer hardware or software."
 

Cons

"The initial setup was complex."
"The IP intelligent services are good for mitigating threats, but there are also false positives. So, it's not a standalone solution that can cover everything."
"I sometimes encounter issues with the porting of F5 BIG-IP DNS."
"The initial setup is a step-by-step process, so it can be a bit complicated for someone who's using it for the first time."
"It would be great to see a F5 BIG-IP DNS cloud version. What we within the Australian government are looking at doing is utilizing a secured DNS service much the same as the English GCHQ version of their protected DNS service."
"The solution is complicated to use."
"The messaging between NGINX and F5 should be simplified."
"CNC (control and command) communication would be beneficial. We would like to have control and command blocking to prevent visiting malicious websites."
"It needs to be more secure for production environments."
"The price could be improved."
"It needs to be more secure for production environments, currently, it is reliable and secure but as per new internet attacks, it should be ready with a proactive approach to eliminate attack chances."
"It addresses a specific risk related to malicious sites but doesn't cover broader security aspects."
"The reporting system needs improvement. They should make is that we can customize it so we can add, remove or change its interface but they use a template. The reports cannot be changed."
"Reporting is not done in real-time. Rather, it is done in 15-minute intervales. This is something that should be configurable by the admin."
 

Pricing and Cost Advice

"In some cases, it is expensive."
"You cannot do much around DDoS protection without an additional license from F5."
"BIG-IP DNS is more expensive than its competitors like Citrix, but it gives good value for money."
"The on-prem version is only available on a yearly license, but the cloud version can be paid for on a day-by-day basis."
"Cost is a factor. It is really costly."
"They are competitively priced."
"I would rate the pricing a three out of ten, with ten being a low price."
"This product is quite pricey but if you compare the feature set and its compatibility with similar products on the market, you would understand why it's that price."
