How do I get proof that Zscaler is actually stopping advanced phishing?

Hi everyone! 👋 I'm still pretty new to the whole enterprise security world, and my team is looking into Zscaler for web security. I keep hearing about "advanced phishing" protection, but I'm having a hard time finding concrete proof or data.

Could someone explain, in a beginner-friendly way, what kind of logs or reports I should ask for to actually verify it's blocking these sophisticated attacks? Like, if I wanted to see a real example that got stopped, where would I look in the admin portal?

Maybe a screenshot of a specific log entry or the exact API call to fetch that data would be super helpful! I want to move beyond marketing claims and see the evidence for myself.

Thanks so much in advance for any guidance! 😊
