Bring Your Own Keys, Safely: The BYOK Security Model Behind ModelPlane
If you're building on top of LLMs, you've already made the security decision that matters most: you're not training your own models. You're renting intelligence from someone else's API. The question is how you manage the credentials that unlock that intelligence.
Most teams hardcode a provider key into a service, or worse, share one key across an entire organization. When that key leaks—and it will—you're not just out a few dollars. You're exposed to prompt injection attacks, data exfiltration, and a billing nightmare that takes weeks to untangle.
The solution isn't to stop using LLMs. It's to route your traffic through a gateway that treats credentials as first-class, tenant-isolated secrets. That's the BYOK (Bring Your Own Key) model at the heart of ModelPlane. It's not just about convenience—it's about building a security boundary between your application and the providers you depend on.
