Rein offers a fresh approach to application security by providing a comprehensive visibility layer that operates without agents. The platform tracks every user interaction, resource access, and API invocation across development, staging, and production environments. It emphasizes real-time behavior monitoring, allowing users to identify deviations from established norms without the interference of proxies or sampling methods. This promises a level of insight that many traditional security tools struggle to provide, claiming 100% coverage with minimal impact on system performance. The technology is designed to be efficient, using just 0.1% CPU and 20MB of memory, while processing requests in 400 microseconds. Users report that this visibility translates to a significant reduction in deployment headaches and performance issues, often associated with traditional security measures. Rein's agentless approach eliminates the need for complicated setups or language-specific solutions, making it accessible and quick to implement. Testimonials from users highlight a shift in perspective on application security. Many express excitement about Rein's ability to reveal the real-time status of applications and their security posture, suggesting it could replace a range of existing tools from API security to software composition analysis. The platform's patented technology allows for unprecedented insight into application behavior, drawing a clear distinction between traditional security measures and Rein’s approach.
