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

Client-side security protects your web applications where they actually run–in your users' browsers. While traditional security tools monitor your servers, they miss the real attack surface where all your applications execute. Your website loads hundreds of third-party scripts for analytics, marketing tools, payment processors, and support widgets. If just one of these gets compromised, attackers can steal credit cards, session tokens, or personal data without you or your users knowing. Client-side security gives you visibility and protection where your apps actually operate.
