What's the types of Professional Services offerings are available?

Our current vendor, provided a package of SOC + PS + TAM + Engagement manager (also QBR's, monthly reviews and personalised follow ups regarding new vulnerabilities) as part of managed could WAF.

We're looking into moving into f5's Silverline Cloud WAF and before making any official sales calls I wanted to understand the managed service and professional service package offered as part of a basic managed cloud WAF offer. I understand that f5 has WAF administration offers reviewing, updating, and maintaining your F5 WAF policies. additionally, implementation and onboarding workshops are available.

But is this a part of the basic WAF package? What are the services they we're expected to pay an additional monthly fee for?
