Our company wants to put F5 before all Azure Web apps and App services and want to remove the usage of Application gateway. We are using 13 version of F5. What additional modules do I need to achieve this functionality. we have ltm and asm modules.
Apart from LTM , if you want L7 protection ASM/AWAF is required,
also for API traffic Protection like Rate limit, authentication APM module is required along with AWAF module.
