Helps deal with DNS DoS attacks and corrupt DNS requests

I know my company does come across problems related to the product, sometimes related to a configuration issue or a bug. My company receives good support from EfficientIP DNS Guardian's team, who are responsible and passionate about the product. As far as I know, all of my company's challenges and issues have been successfully resolved. I can't think of any weaknesses or issues which I would like to highlight in a significant manner. EfficientIP DNS Guardian has a certain default behavior that didn't meet our company's requirements. After the consultation with EfficientIP DNS Guardian's IT support, a configuration changed the product's default behavior, which was undesirable for us, to a desirable behavior. Certain issues happen in every product.

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.
