RASP Security Review

RASP Security Review matters because static defenses no longer hold the line. Runtime Application Self-Protection (RASP) watches code in execution, intercepts malicious inputs, and stops exploits at the moment they occur. Unlike firewalls or scanners, RASP integrates directly into the app, inspecting the actual runtime context. That means SQL injection, command injection, and deserialization attacks can be blocked before damage spreads.

A proper RASP security review starts with visibility. You need to see every request, every function call, every data flow that could be used against you. Logging is important, but real-time detection is better. The best RASP systems embed lightweight agents into your application. They analyze behavior patterns, detect anomalies, and enforce rules without slowing performance.

Coverage is the second step. RASP should protect APIs, web apps, and microservices alike. If the review shows blind spots—like uninstrumented endpoints or unsupported frameworks—fix them fast. Attackers probe for gaps and hit where you are weakest.

Configuration matters. Default settings are rarely enough. Rules need to match your threat model. A RASP review should test these rules against realistic attack traffic. Simulate injection payloads, header poisoning, and path traversal attempts. The strongest platforms block automatically and trigger alerts for every blocked request.

Performance impact is the final test. RASP that slows down requests or adds latency will be turned off by developers under pressure. A serious review confirms any overhead is in milliseconds. Good RASP security strikes the balance: maximum protection with minimal friction.

Runtime Application Self-Protection is no longer optional for teams facing real-world threats. A thorough RASP security review ensures the system is tuned, complete, and ready to stop attacks while code runs. Don’t wait for the next breach to find your blind spots.
