Your users' email addresses, page views, and payment behavior can be siphoned off.
The impact of a data loss incident is hard to measure and can have impact for years following the event. No-one wants to buy from a vendor that puts their data at risk. Demonstrating best effort to preven data loss incidents does not suffice in the public opinion.

Frequently Asked Questions
We monitor every script running in the browser and log all access to sensitive data. We flag immediately any script that tries to access or send user data without context or consent.
Absolutely! Cside gives you flexibility by allowing you not to block a script entirely. You can set your policies, like allowing your chat tool to load, but block it from reading email fields or tracking users' pre-consent.
Non-malicious but unmanaged scripts are common sources of most data leaks. Samples of these are analytics tags that read too much and pixels that weren't updated for new privacy rules. We can help you detect and correct this before it becomes a compliance issue.
The answer is no. Cside loads separately and designed for production environments. It does its job without causing latencies or blocking rendering. We even cache static scripts to improve performance.
