What is Free 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.

Contrast Security
Contrast Security
Modern software development must match the speed of the business. But the modern AppSec tool soup lacks integration and creates complexity that slows software development life cycles. Contrast simplifies the complexity that impedes today’s development teams. Legacy AppSec employs a one-size-fits-all vulnerability detection and remediation approach that is inefficient and costly. Contrast automatically applies the best analysis and remediation technique, dramatically improving efficiencies and efficacy. Separate AppSec tools create silos that obfuscate the gathering of actionable intelligence across the application attack surface. Contrast delivers centralized observability that is critical to managing risks and capitalizing on operational efficiencies, both for security and development teams. Contrast Scan is pipeline native and delivers the speed, accuracy, and integration demanded by modern software development.Starting Price: $0 -
