F5 AWAF Policy learning phase opinion

I suggest taking the F5 AWAF training F5 Training Programs and Online Classes | F5 as configuring F5 AWAF requires knowing the web app (how complex the web app is, how often it is changed etc.) , the organization you work for (banks and fintech usually want no automatic policy as security there is first or if there is TEST/UAT/preprod environment or not) , the network (the web app and network is something the community does not know but you know it) and  then F5 and AWAF as to implement the correct configuration. 

Maybe you can implement AWAF policy if you have strong IT background by going through the operations guides and labing it out.

Also maybe involving F5 PS (Professional services ) or experienced external F5 Consultant for initial deployments then taking it over from there will be beneficial.

The F5 community can assist with more specific questions but general knowledge of the F5 products is needed to successfully utilize them even to know what question you need an answer for from the community.
