What is cside? cside is a browser-layer security platform that gives organisations complete visibility and control over the third-party JavaScript running on their websites. It intercepts every script before it reaches the user, captures the full payload, and analyses runtime behaviour in real time. Third-party scripts power modern websites. Analytics, chat, payments, advertising, and session replay tools all inject JavaScript that runs directly in your visitors' browsers. You didn't write that code. You don't control when it changes. And you have no idea what it does at runtime.
