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.
