Granular security policies have protected critical applications and ensure safe user and admin access
Improvements could be made regarding the log information from the backend CLI. There are enhancements needed; if a request gets blocked on the TCP layer, there should be traces or data to verify which source generated these requests, including the source and port information for initiation. These data are missing from F5 Advanced WAF. Besides that, another improvement could be refining the bot detection to minimize false positives; it should be able to verify more granularly between legitimate and non-legitimate clients. Overall, I find everything else good. A wish list feature I have is for the Technical Assistance Center (TAC) to respond more promptly. Their response time needs improvement; while they do not take excessive time, it can be enhanced, especially given it is a security product.
