How does Aarvion prevent prompt injection from causing harm?

Aarvion authorizes the action, not the prompt. Even if a prompt injection jailbreaks the model, the resulting action must still pass your deterministic policy at the proxy before it can touch a real system.

Does securing agents this way slow them down?

No. Policy enforcement runs at sub-5ms p99, so it sits in the hot path of agent traffic without becoming a bottleneck.

AI agent security

AI agent security with a runtime authorization proxy

AI agent security is about controlling what an agent can do, not just what it says. Aarvion is a runtime proxy that sits between your agents and your enterprise systems and authorizes every consequential action — so an exploited model never becomes an exploited system.

The LLM can be jailbroken. The gateway cannot.

Your AI agents take autonomous actions on internal systems based on input from external users you don't trust. Today the only thing between a prompt injection and a real-money transaction is the LLM's good behavior. That is not a security control.

Aarvion makes the decision deterministic. Every action is authorized by your policy, in real time, before it touches your systems. The audit log proves what was allowed and what was blocked.

Defense at the action layer, inside your VPC

Aarvion is deployed as a proxy in your own cloud. Operational data never leaves your environment, and agents simply route their calls through it.

Deterministic authorization on every CRM, ERP, payment, claims, and identity call
No SDK to embed and no model lock-in — secure any agent the same way
Sub-5ms p99 so enforcement lives in the hot path without slowing agents down
Shadow mode first to observe real traffic with zero production impact

Every block is provable

Security that can't be proven doesn't survive an incident review. Each decision Aarvion makes is signed against your governance and hash-chained, so you can show exactly which actions were blocked, when, and under which rule version.
