Frequently Asked Questions
cside monitors every script running in the browser and logs all access to sensitive data. If a script tries to access or send user data without proper context or consent, we flag it immediately.
Yes. With cside, you don't have to block a script entirely. You can define granular policies, like allowing your chat tool to load, but block it from reading email fields or tracking users pre-consent.
Most data leaks come from non-malicious but unmanaged scripts like analytics tags that read too much, or pixels that weren't updated for new privacy rules. cside helps you detect and correct this before it becomes a compliance issue.
No. cside loads asynchronously and is optimized for production environments. It wraps script execution without introducing latency or blocking rendering. We cache static scripts to even improve performance.
