What Runtime Application Self-Protection Software Companies do

Runtime Application Self-Protection (RASP) Software is a specialized security technology designed to detect and prevent attacks on applications in real-time. By integrating directly into the application's runtime environment, RASP offers dynamic protection against threats such as SQL injection, command injection, and API abuse. This approach allows for a more personalized security strategy that leverages an application's internal state and context, making it capable of identifying and mitigating threats that traditional security measures might miss. The primary use cases for RASP software include safeguarding web applications, mobile apps, and API endpoints from malicious activities during their operation. Its typical features include real-time threat detection, automated response capabilities, and detailed logging of security events. Common buyer personas for RASP solutions typically include security operations teams, software development teams, and IT professionals seeking to bolster their application security posture without compromising performance or user experience.
