Find LLM Security Gaps Before Attackers Do

What BastionLLM does

BastionLLM checks your LLM endpoint for real attack paths, including jailbreaks, prompt injections, and data leak patterns.

You provide the endpoint details once. We run OWASP-aligned tests and return results your team can triage, fix, and verify.

Why this matters

Why this matters:

• Attackers can steer model behavior with plain text in user input, docs, or tool output.
• Prompt injection can override rules, and jailbreaks can bypass refusal and safety logic.
• Prompt leak attempts can expose hidden instructions, business logic, and internal context.
• One-time pre-launch tests are not enough after model, prompt, or integration changes.
• Repeatable OWASP-aligned scans catch regressions before they reach production users.

Here's how it works

Here's how it works:

1. Connect your real endpoint with request schema, headers, and response parsing paths.
2. We send controlled adversarial prompts across prompt injection, jailbreak, and leak tests.
3. We score each payload and show raw outputs so engineers can reproduce each failure.
4. Run scheduled scans to detect regressions as prompts, models, and integrations evolve.
