What reviewers mention most
Script-level visibility
The most common first reaction: finally seeing every script that runs on their site — what it does, where it comes from, and whether it should be there.
Responsive, engineering-led support
Fast, non-salesy support comes up in nearly every review, from small startups to companies with thousands of employees.
PCI DSS without the headache

No performance cost
