The Enterprise Agent Security Platform

SEE & PROTECT
EVERYTHING
YOUR ENTERPRISE
AGENTS DO.

Connect every action to business outcome. Enforce any business policy. Get ready for an audit. All while keeping your data private. Let developers ship new agentic products, while Rein has your back.

Enterprise agents are a different animal.

  • 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.

  • You must ship them

    It’s raining enterprise agents - your board is pressuring, R&D is pushing, and you are stuck in the middle.

Protecting Enterprise Agents Requires Four Key Elements

  • Discovery

    Know what every provider, agent, MCP, and tool are actually doing in real time and connect it to business outcomes, with auto-discovery of everything they do. Real-time inventory across cloud, on-prem, and serverless, and shadow AI detection with no manual onboarding.

  • Guardrails

    Protect with context - without breaking workflows. Enforce guardrails dynamically and in real time with business-aware controls based on user, role, and data sensitivity. Block, allow, or respond inline without disrupting the experience, all through a single policy plane spanning providers, agents, MCPs, and tools.

  • Posture

    Find real 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.

  • Compliance

    Be ready for AI audits without slowing adoption, with audit-ready evidence mapped to SOC 2, ISO 42001, the EU AI Act, and data privacy laws. Continuous compliance monitoring instead of point-in-time checks, and out-of-the-box controls for every major AI framework.

How the Rein platform works

One simple to deploy sidecar, and Rein is monitoring and protecting any business risk.

  • Discover what your enterprise agents do

    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. This end-to-end execution chain eliminates the blind spots that perimeter and gateway tools leave behind.

  • 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- 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

The Rein platform is built to secure agentic systems across industries with radically different risk profiles, from financial fraud prevention and healthcare data privacy to complex SaaS environments.
