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.
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.
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.
"By the time you detect it, you've already paid for it."
APIs Scaled. Control Didn't.
The problem isn't storing API keys anymore.
It's controlling what happens after they're used.

Enforyn is the missing layer — real-time control over every API request.
Insert a Control Layer
Between You and
Your APIs
API Enforyn intercepts every request, enforces your security rules, and keeps your real keys hidden -- permanently.
Up and running in minutes
A clean, focused path to security.
Request Lifecycle
Every request passes through our multi-layer validation pipeline before reaching your external API.
"Most tools log requests. We decide if they happen."
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.
Enforyn
Set hard cost and request limits. Never pay for runaway usage again.
Anomaly Detection
Spots unusual patterns, unknown IPs, and traffic spikes before they become incidents.
Real-Time Visibility
See everything. Control everything. One unified control plane for all your API keys.
Policy Engine
Define granular rules per key, per project, per endpoint.
Built for teams that ship fast
Whether you're building AI apps or scaling SaaS -- we've got you covered.
AI Native Applications
LLM costs can skyrocket in minutes. Enforyn stops runaway OpenAI/Anthropic calls before they affect your bottom line.
Global SaaS Platforms
Map every feature to specific API costs. Control per-customer usage, prevent abuse, and keep your unit economics stable.
The Shield Gap
One intelligent layer makes the difference between consistent profitability and a catastrophic bill.
Unprotected Keys
Standard architectures expose your primary API keys to the client or unsecured env files.
Enforyn Layer
Strategic isolation of real keys. Total visibility. Zero chance of budget explosions.
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.
