Rein is the first security solution to uncover the reality behind your AI agents and apps, by providing Full Agent Tracing. It allows you to capture everything an AI agent does, why it does it, and who initiated it. The result is complete visibility and control, so organizations can adopt agentic AI safely and at speed.

Production agents are exploding. But today’s approaches such as LLM gateways, prompt-layer controls, and eBPF-based monitoring leave critical AI risks unchecked. The outcome is predictable: major gaps in visibility, security posture, compliance, and guardrails that ultimately slow down AI adoption.

The Rein Agentic Security Platform enables Fortune 500 companies to move forward with confidence by giving them the ability to see and control everything their agents and applications do:

See every prompt, service call, tool invocation, and resource touched, with full attribution to the initiating user or system
Enforce policies and dynamic guardrails across all AI risks, from attacks to errors to hallucinations
Operate on a fully private, in-org data model with simple, low-friction deployment

Built on the same foundation, Rein powers modern AppSec across the board, for both AI and non-AI use cases, from Runtime SCA and exploitability to AI-powered SAST, runtime API security, and detection and response.

This isn’t “shift left” or “shift right.”
It’s a new axis entirely.

Rein eliminates guesswork in Agentic AI Security and AppSec and reveals how applications actually behave in production.
