Ensures reliable web application security and offers comprehensive load balancing solutions
When it comes to denial of service or DNS security, F5 is not the best vendor as dedicated vendors such as Arbor for denial of service and Infoblox for DNS security offer more comprehensive solutions. The main features such as WAF and load balancing do not generate complaints. F5 BIG-IP DNS is not the best for DNS denial of service because they handle it as part of BIG-IP features, mainly used for GSLB, while other vendors provide complete DDI solutions, including DHCP, DNS, and IP address management, along with specialized DNS security, offering much more than just GSLB and basic recursive DNS security. The two main concerns are DNS related and denial of service, areas where F5 BIG-IP DNS could improve, and they could do better as they are not the best vendor, indicating ample room for improvement especially since those are not their main specialties.

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

"BIG-IP DNS's best feature is the Global Traffic Manager (GTM)."
"The solution is easy to configure and deploy. It is scalable and works without any downtime. F5 BIG-IP DNS is a flexible solution."
"F5 BIG-IP DNS has been rock solid in terms of stability for years."
"The main features valued in F5 BIG-IP include high availability, scalability, and protection of applications from attacks."
"F5 BIG-IP DNS stands out as they are number one when it comes to WAF and load balancing technologies, and they have plenty of add-on features such as APM and AFM to handle DDoS attacks, DNS security, and GSLB."
"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."
"The configuration process is straightforward, making it easy to set up wide IPs and distribute traffic across local US sites and data centers via VPN."
"F5 technical support is quite good and they follow up if there are any issues."
"When compared with other products, Webroot DNS Protection is the best to secure the end users."
"DNS protection is valuable."
"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."
"Almost everyone who uses it is happy about the product. I don't get any types of complaints from my clients."
 

Cons

"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."
"I would like to see more marketing documentation, rather than technical documentation."
"The costs could always be a bit lower."
"The analysis services needs improvement."
"There is room for improvement in pricing. It is very pricey."
"CNC (control and command) communication would be beneficial. We would like to have control and command blocking to prevent visiting malicious websites."
"Scalability is a concern, it could be improved."
"When it comes to denial of service or DNS security, F5 is not the best vendor as dedicated vendors such as Arbor for denial of service and Infoblox for DNS security offer more comprehensive solutions."
"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."
"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."
"It needs to be more secure for production environments."
 

Pricing and Cost Advice

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