About
Rein Security provides an agentless application security platform that gives CISOs and AppSec teams real-time visibility into how applications actually run in production. The platform correlates every request, response, resource, API and line of code to surface validated risks instead of theoretical findings, across API security, SCA reachability, detection and response, and AI/MCP protection. Co-headquartered in Tel Aviv and New York, Rein is used by enterprises such as Lemonade and HiBob to focus remediation on what truly matters in production.
