How Client-Side Protection works
Imperva’s Client-Side Protection gives security teams visibility and control over any third-party JavaScript code embedded in your web applications.
Continuously monitoring all JavaScript services, it only allows pre-approved services to execute, meaning any new JavaScript services or changes are blocked until authorized.
And, if any JavaScript code is poisoned, and attempts to send data elsewhere, your security team is the first to know.
