While we haven't explored AI-driven features yet, it's part of our roadmap for future versions. I would recommend F5 BIG-IP DNS to others in the industry. Overall, I would rate it an eight out of 10 as it meets our current needs but it will always have room for improvement.

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.
