What is Runtime Application Self-Protection (RASP) Software?
Runtime Application Self-Protection (RASP) software is a security solution designed to protect applications in real time while they are running, providing active defense against attacks by detecting and mitigating vulnerabilities as they occur. Unlike traditional security tools, which primarily focus on perimeter defense or static scanning, RASP operates within the application itself and monitors its behavior during runtime. It can automatically block malicious activity, such as SQL injection, cross-site scripting (XSS), and unauthorized access, by analyzing both application traffic and the application's internal behavior. RASP is particularly valuable for protecting web applications, mobile apps, and APIs from advanced threats, ensuring the security of applications even if they are deployed in dynamic or cloud environments.

Reflectiz
Reflectiz
Runtime application self-protection instruments the application server to detect and block attacks as code executes. Reflectiz applies that same runtime principle to the half of a modern web application RASP cannot see: the code executing in the visitor's browser. Third-party scripts, tag managers, trackers, and iFrame-embedded content run outside the server entirely, so a skimmer injected through a vendor's CDN never touches instrumented application code. Reflectiz observes real browser execution continuously, baselines what each script does, and alerts the moment behavior deviates, catching cases such as a legitimate analytics tool that starts reading checkout form fields or a pixel exfiltrating data to an unapproved endpoint. It deploys with no agent, no code change, and no performance cost. Reflectiz complements server-side RASP rather than replacing it, and mature programs run both.Starting Price: $5000/year -
