"The next-generation aspect of [Fastly]'s WAF was very compelling for me because I need WAF management that is, essentially, effortless—something that can be set up really quickly but still be a major part of our security program. If I get a notification from [Fastly] that a new user is a bad actor, I can immediately block him, which is very important for me, and for our customers. I don't think any other solution on the market can give us all that."
