Runtime application self-protection (RASP) tools are designed to safeguard application servers by identifying and thwarting attacks as they happen during code execution. Reflectiz takes this concept a step further by focusing on the client-side aspect of modern web applications that RASP typically overlooks: the code that runs in users' browsers. Elements like third-party scripts, tag managers, trackers, and iFrame content function independently of the server, allowing malicious code injected through a vendor's CDN to bypass the protections on the server-side application. Reflectiz continuously monitors the execution in real browsers, establishing a baseline for each script's normal behavior and providing immediate alerts whenever deviations occur. This capability helps identify situations where, for instance, a standard analytics tool begins to access sensitive checkout form fields or a tracking pixel sends data to unauthorized destinations. The implementation of Reflectiz requires no additional agents, code modifications, or impacts on performance. Instead of replacing server-side RASP solutions, Reflectiz works in tandem with them, making it an ideal addition for organizations with established security programs that utilize both technologies.
