API keys, not prompt injection, are the most common AI security leak

Many discussions on AI security overlook the most common vulnerability: hardcoded or client-exposed API keys. This issue, similar to past web development mistakes, arises when developers embed LLM API keys directly into frontend code for speed, failing to move them server-side. While model-layer security like prompt injection is important, basic access-layer hygiene, such as using a server-side API security gateway to prevent key exposure, is often the missing piece in actual breaches.

    Most AI Security Advice Ignores the Most Common Leak: What an API Security Gateway Actually Protects

    <p>Search "AI security" and most of what comes back is about the model layer: prompt injection, jailbreaks, output filtering, data leakage through model responses. All real concerns. But in the LLM applications I've actually looked at — side projects, hackathon demos, more than a…
