Custom-built enterprise agents are a different animal.

They require a new type of runtime security

Unlike chatbots, SaaS, or endpoint agents, custom-built AI agents can only be monitored and protected by observing their AI-native runtime- the execution layer where they actually take action. That means seeing not just the prompts they receive, but the real-world downstream effects of every prompt.
They take real actions.

Unlike productivity agents, when prompt injection lands at an enterprise agent, the damage isn’t bad text - it’s real transactions and real user data.
They connect to your crown jewels.

Enterprise agents plug directly into payments, customer data, and source code, where one misconfiguration can leak sensitive data through normal-looking API activity.
They operate inside your workflows

Enterprise agents are everywhere - in your CI, cloud and toolsets, which means their hallucinations are way worse than misconfigurations.
They require audit trails you don’t have

You have what the agent said. Not what it did to your customers, your data, or your books. SOX, HIPAA, and EU AI Act auditors need both.

Protecting Enterprise Agents with Rein: AI-Native Runtime Security

Visibility

See what every agent, MCP, and tool are actually doing in real time and connect it to business outcomes, with 100% execution visibility into everything they do at the AI-Native Runtime. See every database access, every API call, every prompt and response and correlate it all to gain context - the Who, the What and the Why.
Controls

Prevent any rogue agent behavior with context - without breaking workflows. Enforce guardrails dynamically to prevent anything from prompt injections to hallucinations, and buy time until a patch can be applied. Just turn on Rein's "Protect Mode", and your agent baseline is automatically enforced, blocking any action that deviates from it. As simple as that.
Posture

Find real exploitable risks fast - from prompt abuse and vulnerable code to software supply chain threats. Detect issues in real time across agents, models, tools, and dependencies. Every finding includes full context across the user, agent, and data path, so teams can understand what happened, why it matters, and remediate immediately with near-zero MTTR.
Privacy

Instead of using gateways that divert sensitive data to outside security tools, use Rein on your own servers to keep complete data sovereignty. Get 100% visibility into agentic actions, while giving up on 0% of your data privacy.

How the Rein platform works

Rein deploys via a simple sidecar, and uncovers 100% of the AI-Native Runtime, where agents perform all of their actions.

Discover what your enterprise agents do

Unlike cloud runtime, kernel runtime or LLM gateways, Rein observes the AI-Native Runtime - the actual execution layer of the agent. This way, you go beyond inputs and outputs to uncover the full execution chain: every prompt, every service call, every tool invocation, every resource touched- and who triggered it.
Put in dynamic guardrails for any business risk.

Stop attacks, errors, and hallucinations alike. Instead of chasing known threat signatures, Rein learns what “normal” agent behavior looks like at the AI-Native Runtime- and enforces guardrails on any deviation. Whether it’s a prompt injection, a misconfigured tool, a user mistake, or an AI hallucination- nothing slips through the cracks.

For Any Type of Enterprise Agent

“Rein is the first platform we've seen that's purpose-built for the production agents that actually run the business.”

Jay DePaul, Chief Cybersecurity & Technology Risk Officer, Dun & Bradstreet
“Rein gives builders and defenders clear sight lines into agent behavior and guardrails that don't break workflows.”

Philip Miller, Global CISO at H&R Block
“For the first time, Rein shows us what’s really happening in our agents & apps. When something deviates, we know it’s real.”
