The problem

AI agents act. You find out later.

Most AI deployments rely on the model to refuse. That isn't a control. And controls built into the agent are not independent. You cannot verify them, your security team cannot see them, and an auditor will not accept them. When an agent shells, posts, or signs, the act has already happened. Prosader sits outside the agent. It enforces at the tool call level regardless of what any agent claims to do internally.

No enforcement
Agents act before any rule is consulted.
You learn what happened from logs, not from controls. By the time review begins, the action is committed.
Internal controls are not independent controls
An agent saying it has safeguards is not a safeguard.
Some agents are built with approval steps. Most are not. But even the ones that do have controls, those controls live inside the agent itself. They are not independently auditable, not consistent across agents, and not visible to your security team. Oversight that lives inside the thing you are trying to control is not trustworthy oversight.
No evidence
Audit trails auditors won't accept.
Chat transcripts and model responses aren't admissible. Evidence needs signed, immutable receipts tied to specific actions.
<2ms
Median enforcement latency, in-path with the agent's tool call.
100%
Decision coverage. Every tool call evaluated, no sampling.
Model agnostic
Works with Claude, GPT-4, Llama, Gemini, and any agent framework.
Signed receipts
Immutable, timestamped, and admissible as evidence in audit.
How it works

Four steps, one round trip.

A single in-line enforcement engine between your agent and its tools. No batch jobs, no after-the-fact review.

01

Agent calls a tool

Your AI agent invokes a tool: bash, file write, API call, database query.

02

Prosader intercepts

The SDK or proxy captures the full tool call before execution begins.

03

Rules evaluate

The enforcement engine evaluates all active rules in <2ms. Verdict: ALLOW, DENY, or STEP_UP.

04

Receipt issued

A signed, immutable receipt is written. Verdict, rule matched, latency, timestamp.

Capabilities

What the engine does.

A flat list, no tiers. Every capability is in every deployment. What varies is rule packs, throughput, and support.

Rule-based enforcement

YAML rules, all standard operators, version-controlled. Define what your agents can and cannot do, in source.

DENY STEP_UP ALLOW

Step-up approvals

Human-in-the-loop for high-risk actions. Approvers sign off, requests time out, and the full chain of custody is retained.

Human-in-loop Chain of custody

Immutable audit trail

Every decision produces a signed receipt. Export full PDFs for audit, time-window reports for regulators.

Signed receipts PDF export

Rule packs

Pre-built enforcement bundles for common risk domains. Drop in, tune, version. Maintained against framework updates.

Financial PII Infosec

Real-time metrics

Prometheus endpoint with verdict counts, latency histograms, rule-fire rates. Grafana dashboards ship in the box.

Prometheus Grafana

SDK & proxy integration

Three-line Go SDK, or run as a sidecar proxy. Drop into existing agents without rewriting the orchestration layer.

Go SDK Proxy mode REST API
Compliance

Evidence, not just policy.

Regulators want demonstrable controls, not internal policies. Prosader's signed receipts map directly to the evidence requirements of the frameworks your auditors test against.

Export decision logs as PDF reports scoped to any time window, rule pack, or agent session. Receipt content is signed at issuance and re-verifiable years later.

Integrations

Works with the tools your team already uses.

Prosader pushes every decision outbound as a signed JSON event. Security, compliance, and engineering teams get AI activity in the platforms they already monitor.

Generic webhook
One URL field in Settings. Every ALLOW, DENY, and STEP_UP is delivered as signed JSON within milliseconds. Works with any HTTP endpoint.
Built in
S
Splunk
Point the webhook URL at Splunk HEC. Decisions arrive as structured events. Build dashboards and alerts over AI agent activity in minutes.
Via webhook
Elastic / OpenSearch
Ingest decisions into an Elasticsearch index via the webhook. AI audit events become searchable alongside your existing security logs.
Via webhook
Microsoft Sentinel
Forward decisions to a Sentinel custom log table via the webhook. DENY and STEP_UP events trigger existing SIEM rules and analyst playbooks.
Via webhook
Datadog
Route the webhook to a Datadog log intake endpoint. AI events flow into your existing monitors, anomaly detectors, and SLO dashboards.
Via webhook
Prometheus / Grafana
Prosader exposes a /metrics endpoint in Prometheus format. Scrape allow rate, deny rate, step-up count, and engine latency into your existing Grafana dashboards.
Built in
PagerDuty / OpsGenie
A webhook carrying DENY or STEP_UP events triggers an incident. On-call teams are paged automatically when an agent hits a critical rule.
Via webhook
REST API
Every resource — receipts, sessions, rules, step-up decisions, reports — is available via the admin REST API. Build your own integrations or pull audit data into internal tooling.
Built in
1
Get your intake URL from your platform. Splunk calls it an HEC endpoint. Datadog has a log intake URL. Sentinel uses a custom log API. Each platform generates one in a few clicks.
2
Paste the URL into the Webhook URL field in the Prosader dashboard under Settings. Add an optional secret to verify requests on the receiving end.
3
Click Send test to confirm the connection, then walk away. Every AI decision flows to your platform automatically from that point — no agents to install, no SDKs, no restart.
