Why do WAF logs miss evidence of client-side data theft?

Only the initial delivery of third-party scripts to browsers can be captured by WAF logs. Malicious JavaScript steals user data, bypassing your infrastructure via direct browser-to-attacker communication. You can see through your WAF logs the script that was delivered successfully, but it's blind when it comes to the data collected, manipulated, or exfiltrated that happens on the client-side.
