The problem with WAF is discussed in https://users.ece.cmu.edu/~adrian/731-sp04/readings/Ptacek-N....

One of the authors of the paper has said "WAFs are just speed bump to a determined attacker."

Locks are a speedbump for a lockpick.

Doors are a speedbump for a car.

Well yeah, sure, doesn't mean I'm going to have an open doorframe or a door without a lock.

The difference is that a door tends to be the only thing between you and an attacker. A speedbump is better than nothing.

This isn't like having a lock on your door, this is like having a cheap, easily pickable padlock on your bank vault. If the vault has a proper lock then the padlock serves no purpose, and if it doesn't then you're screwed regardless.

And to extend the metaphor to cover the false positives these systems produce, sometimes the padlock seizes shut if the air temperature is in a certain range, and the team that put it there refuses to take responsibility for the fact they've locked your customers from accessing their assets with the valid key.
