BEHIND THE REPORT

A method you can read. Limits you can see.

A favourable result is an observation about the attacks executed, not a security certification.

A traceable catalogue

571 test prompts across 28 families, referenced to OWASP LLM categories. Explore what gets tested.

Verdicts you can review

Automated checks are supplemented by ARES review on selected cases. Coverage and disagreements are shown when a review is available.

An explicit scope

Testing targets the selected model or endpoint. A direct provider call does not automatically reproduce your application, RAG data or tools.

Before your first test.

What do I need?

An API key you are authorised to use, the exact model ID and your email. For a custom endpoint, use an HTTPS URL compatible with OpenAI chat completions responses.

What is free?

The 30-attack test, its results, a downloadable PDF and the private link sent by email. Guest access lasts 24 hours after first opening, within 30 days of the test. Your model provider bills API calls.

What does €49 unlock?

One full 571-attack analysis, its PDF report and 12 months of report access. After payment confirmation, add your key again to run the full analysis. It replaces the free preview at the same private link. It does not start a subscription or unlock monitoring.

How long does it take?

Timing depends on the model’s speed and your provider’s limits. Your report shows progress. You can leave the page: the analysis continues and an email lets you return to the results.

How is Pro different?

The one-off report is for a single analysis. Pro lets you retest with the full catalogue and evaluate production traces through the API, with 5,000 successful evaluations per monthly period across up to 3 systems.

Do I have to leave my API key with STAIPH?

No. It is encrypted during testing and deleted on completion, failure or expiry. It is not reused for a new analysis without being entered again.
