Rein Security Information

Rein is the security layer for Custom-built Enterprise Agents - the production AI agents running businesses worldwide. Enterprise AI adoption has evolved - from third-party chatbots, to employee productivity agents, to Enterprise Agents: AI agents that are processing payments, approving insurance claims, interacting with personal data, and accessing medical records. This new class of agent demands security built specifically for it. By sitting as a sidecar to the agent (not a gateway, proxy or eBPF), Rein’s platform protects enterprise agents with four pillars. First, it delivers full visibility into every action the agent takes, showing exactly how those actions connect to business outcomes. Second, it manages your agents' posture - from governing every action, to securing the agent's code, vulnerability management and supply chain security, compliance and governance - all under one roof. Third, it enforces guardrails over every agent action stopping it right before bad actions execute. And fourth, it does all of this while keeping data completely private and inside the organization. Customers across Finance, Healthcare, SaaS, and Energy, including Dun & Bradstreet, Lemonade, Swimlane and HiBob use Rein to secure the enterprise agents that drive their business.
