They run on user devices you don’t control, communicate over unpredictable networks, and face attackers who are faster, smarter, and increasingly automated. In this reality, security can no longer sit outside the application and hope for the best. It has to live inside the app itself. That is where runtime self-protection comes in.

This internal positioning is what allows RASP security to respond in real
