Suitable for use cases around multiple data centers and provides good stability
F5 is working on improving its identity management features. This is an important area for improvement, as it is a key component of Zero Trust architecture. So, when I was working on the zero-trust architecture, I noticed that there was a lack of documentation. The National Institute of Standards and Technology (NIST) has published some documentation and frameworks for ZTA implementation. In the NIST framework, multiple vendors can be used for different components of the architecture. For example, for identity management, common vendors include Azure, Intune, AWS, Cisco Duo, and Zscaler. I remember reading about F5 mentioned in the context of the ZTA framework. So, it's encouraging to read that F5 is being considered for ZTA implementations. Netskope is also using F5 for their ZTA solutions. I would also like to see all of F5's features integrated into a single box, as it would be the most beneficial for end customers. F5 is already enhancing its security capabilities. Initially, load balancing and security required separate devices, but now F5 offers solutions that combine both functionalities in a single device.

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.

Pros

"Stability-wise, I rate the solution a ten out of ten...Stability-wise, I rate the solution a ten out of ten."
"F5 provides us with a mechanism to accomplish complex product balancing."
"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."
"F5 technical support is quite good and they follow up if there are any issues."
"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."
"F5 BIG-IP DNS is useful, depending on how you use it."
"BIG-IP DNS's best features are DNS monitoring and global service load balancing."
"Almost everyone who uses it is happy about the product. I don't get any types of complaints from my clients."
"Webroot excels in DNS protection, particularly in blocking malicious sites and phishing."
"When compared with other products, Webroot DNS Protection is the best to secure the end users."
"DNS protection is valuable."
"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

"I would like to see deeper integration with VMware in the sense that F5 compliments VMware, in the context of application availability."
"I would like to see more marketing documentation, rather than technical documentation."
"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's initial setup is complex compared to Fortinet."
"The analysis services needs improvement."
"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."
"The initial setup could be easier."
"The costs could always be a bit lower."
"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."
"It needs to be more secure for production environments."
"It addresses a specific risk related to malicious sites but doesn't cover broader security aspects."
"The price could be improved."
"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

"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."
"BIG-IP DNS is more expensive than its competitors like Citrix, but it gives good value for money."
"You cannot do much around DDoS protection without an additional license from F5."
"Cost is a factor. It is really costly."
"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."
"In some cases, it is expensive."
"They are competitively priced."
"I would rate the pricing a three out of ten, with ten being a low price."
