What is client-side security, and why do I need it?

Client-side security protects your website visitors from malicious JavaScript attacks that happen directly in their browsers. Unlike traditional security that focuses on your servers, client-side threats target the scripts running on your actual web pages, like payment forms, chatbots, and analytics tools. These attacks can steal credit card information, passwords, session tokens, and sensitive personal information without a user or admin even knowing. If you handle payments or sensitive data, you need client-side security to protect your customers and meet compliance requirements like PCI DSS.
