Next-Generation AI Runtime Security
Secure every action your AI agent takes
AI runtime security today guards the model and the AI workflow. Agents outgrew that layer: they call tools, reach systems and spend credentials — and that is where the risk moved. OpenGuardrails judges the action, at both ends of every turn, on an open protocol your gateway already speaks.
Run it as SaaS from $20/month, or deploy it privately so events never leave your infrastructure. Built on OGR, the open protocol we contribute to the community.

Under the pitch it is a Policy Decision Point: enforcement stays in your plugins and gateways; every decision — with findings and redaction spans — comes back in real time.
PEP · enforcement
Agent / gateway plugin
Holds the action and forwards the raw model bodies it already carries.
GuardEvent
POST /v1/evaluate
Verdict
allow / block / redact
PDP · decision
OpenGuardrails runtime
Evaluates the action against policies you own; every accepted event is also recorded.

Why next generation
The layer above the model is where agents live
Every action, not just every prompt.
Agents don't only answer — they call tools, reach systems and spend credentials. OpenGuardrails reads the tool call, the resource behind it and the account it used, and judges the request before the model sees it and the response before the agent acts on it.
Built for agents, not retrofitted for them.
Sessions, turns and steps are reassembled from what the gateway already forwards, so a verdict is made in the context of the whole task — not one stateless call at a time.
An open protocol, not a black box.
The runtime is commercial, but the contract it serves is not: OGR is Apache-2.0. What your agents do is recorded against a wire spec anyone can read, any conforming runtime can serve, and any gateway can emit — so the record outlives the vendor.
Console
One console for the whole fleet
Agents auto-register on their first event. Everything an operator touches lives in six modules — three for seeing what the fleet does, three for setting its rules.
See every action
Live monitor
Real-time KPIs, event timeline, flagged breakdown, recent findings.
Explorer
Auto-discovered Agents → Sessions → Turns → Steps → Calls, with transcript drill-down.
Findings triage
Every finding carries a whitelist fingerprint (fp): whitelist a false positive once and it stops affecting decisions — while still being raised and recorded.


Set the rules
Policies
Guardrails and enforcement, assigned to workspaces — hundreds of agents inherit one policy, no per-agent config.
Playground
Test a policy against a sample agent trace before it gates anything real.
API keys
Workspace-scoped ogr_ keys; every event lands in, and every policy resolves from, one workspace.
Pricing

There is no free tier: sign-up completes once a payment method is added, starting at $20/month. Usage limits apply on every plan; prices and plans are subject to change.
Quick start
From sign-up to first verdict
Sign-up is a short guided onboarding — you see the console as you go, and you leave it with a key that already has a policy behind it.
01
Tell us what you run
Pick your agent type — coding agent, personal AI agent, employee-facing agent or customer-facing agent — and your industry and use case. Each type maps to one of the four policy templates, so your workspace starts with guardrails tuned to how that kind of agent actually fails.
02
Get your workspace key
Onboarding creates your workspace and issues its ogr_ API key, with the template policy already assigned — nothing to configure before the first event.
03
Activate with a payment method
Add a card to complete sign-up — Pro from $20/month, no free tier, cancel anytime. Your key goes live the moment the subscription starts.
Then point anything at it
# 1. Sign up and finish onboarding — your workspace key is issued there
export OGR_RUNTIME_URL=https://airs.openguardrails.com
export OGR_API_KEY=ogr_... # from the console, workspace-scoped
# 2. Send an event; watch it land in the live monitor
curl -s $OGR_RUNTIME_URL/v1/evaluate \
-H "Authorization: Bearer $OGR_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"kind": "step/request",
"step_id": "quickstart-1",

}'Any v1.0 plugin from the plugin index speaks this contract out of the box — Higress, dsh, litellm today, more as they are rewritten — and so does your own agent, in two POSTs per model call.
Enterprise
Private deployment
The same OpenGuardrails, licensed to run in your infrastructure — for teams whose events must never leave it. It is the SaaS product, not a lesser edition: same console, same detectors, same Runtime API.
Your infrastructure
Runs on your Kubernetes or VMs against your own PostgreSQL/MySQL, ClickHouse/Doris and Redis. Model-backed detectors route through a model gateway you host — your events and your transcripts stay inside your boundary.
Your identity, not self-serve
There is no sign-up flow in a private deployment. Operators are provisioned by your administrator or arrive through your enterprise SSO — access is governed the way the rest of your security tooling already is.
Licensed annually
Commercial license with support and an SLA, priced on fleet size. Talk to us about a pilot in your environment.
Operations
What an operator should know
Liveness
GET /v1/health is unauthenticated: 200 when the runtime can serve decisions, 503 otherwise. Point your probes at it.
Degraded mode
What an integration does when it cannot reach the runtime is local, pre-configured policy — open by default (proceed, recorded as unjudged), closed as the explicit opt-in for gated categories.
# configured locally at the integration, never fetched fail_mode: security.malicious_command: closed # dangerous actions denied while security.data_exfiltration: closed # the runtime is dark "security.secret_leak.*": closed # .* covers a whole subtree default: open # everything else proceeds, unjudged
One key, one tenant
The ogr_ organization API key proves the tenant, and it is the identity floor: an integration asserting nothing is still fully attributable (one key, one default agent). Every field of the identity four-tuple it fills refines that picture.
Rate limits
600 requests/minute per API key by default. An exhausted limit returns 429 — which conforming clients treat like an unreachable runtime: back off and apply the configured fail mode.
Detectors, composed
Deterministic checks and model-backed detectors (LLM judges, injection classifiers) run hosted in the SaaS — no GPUs on your side. In a private deployment the same model-backed checks route through a model gateway you host, on your hardware. Any OGR-conformant detector composes in the same way — detectors compete, you compose.
The full lifecycle
Runtime is one phase. We cover all three.
An agent you can trust with real work is red-team tested, has guardrails on every action at runtime, and can analyze the hostile files it encounters. Our method throughout is weak-to-strong generalization: small models supervising models 100x larger, in production today. Read the mission →

Our contribution to the community
The open OGR protocol
OpenGuardrails is the flagship runtime, not the only one possible. Everything it speaks — GuardEvent in, Verdict out, over POST /v1/evaluate — is an open, Apache-2.0 specification with published JSON Schemas. Anyone can implement a conforming runtime; every plugin, and every agent integrated per the recipe, will speak to it unchanged. The product is commercial; the contract never will be.
