🚨 This week proved it again: API keys are still the weakest link in modern apps. Most teams only find out after the bill hits. → See how Enforyn prevents this
Runtime Control Layer for APIs

Your API Keys Are
Already a Liability
You Just Don't See It Yet

Once a key is exposed or misused, the damage is already done. Enforyn is a real-time enforcement layer that sits between your app and every API — controlling usage in real time, before it turns into cost or breach.

Keys never exposed Every request controlled Costs always visible

Because monitoring isn't enough anymore.

Real-Time Budget Control for Every API Key

Set limits, enforce policies, and stop runaway spend before it hits your bill — across every provider and every environment.

The Problem

API Keys Are a
Silent Risk

By the time you detect the issue, the cost is already incurred. Most teams have zero visibility into what's happening with their API keys.

Silent Leaks
Keys leak via GitHub, frontend, logs — silently
Invisible Abuse
Abuse is invisible — until the bill arrives
No Runtime Control
No circuit breaker — requests go through anyway
Instant Explosions
Costs explode instantly — no protection layer

"By the time you detect it, you've already paid for it."

The Root Cause

APIs Scaled. Control Didn't.

AI APIs
Unpredictable cost spikes with every prompt
Distributed Systems
Keys scattered across services and environments
Faster Shipping
Speed prioritized over safeguards
Reactive Tools
Existing tools alert after damage, not before

The problem isn't storing API keys anymore.
It's controlling what happens after they're used.

The Gap

Why Existing Tools Fall Short

Secret Managers

Store keys securely
Do nothing after usage

Monitoring Tools

Alert after damage
No control over requests

API Providers

Show usage dashboards
No enforcement layer

Enforyn is the missing layer — real-time control over every API request.

Core Features

Everything you need to stay in control

Five layers of protection working together.

Proxy Key System

Your real API key never leaves our vault. Application clients only ever see a proxy key that you can revoke instantly -- zero exposure, zero risk.

Anomaly Detection

Spots unusual patterns, unknown IPs, and traffic spikes before they become incidents.

Normal Traffic→ Stable
Spike Detected→ Alert
Unknown IP→ Block

Real-Time Visibility

See everything. Control everything. One unified control plane for all your API keys.

FAQ

Frequently Asked Questions

How does Enforyn isolate my API keys?

Enforyn proxies requests through a control layer that never exposes your raw provider keys to client-side code or logs, isolating credentials from the rest of your stack.

Does Enforyn add latency to my API calls?

Enforyn's proxy layer is designed for minimal overhead, typically adding single-digit milliseconds per request.

How long does setup take?

Most teams are up and running in about 5 minutes with no code changes required beyond swapping your API base URL.

How do I migrate existing API keys?

Add your provider keys to the Enforyn vault, swap your base URL to the proxy endpoint, and rotate client-side keys to proxy keys — no downtime required for most stacks.

What happens when a budget limit is hit?

Requests are blocked at the proxy before they reach your provider, alerts fire immediately, and you can adjust limits or revoke keys from the dashboard without redeploying your app.
