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.

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.
