ChatGPT Security Testing for Apps and Custom Workflows

ChatGPT security testing is not only about whether the model refuses unsafe text. It is about whether your application instructions, tools, and data handling stay intact under adversarial conversations.

Run demo scan

Where it fits

  • A ChatGPT-powered support bot can access account details or draft customer actions.
  • A custom GPT-like app uses hidden instructions, files, or tool calls.
  • A team is switching model versions and needs to retest prior attack cases.

Operational steps

  • Create a test profile for the ChatGPT app surface and allowed behavior.
  • Run attack cases for instruction override, hidden prompt extraction, tool coercion, and data leakage.
  • Compare results across model versions or providers when routing changes.
  • Use the report to adjust prompts, guardrails, authorization checks, and logging policy.

Common risks

  • The model refuses obvious attacks but leaks instructions through translation or summarization prompts.
  • Tool calls trust model output without server-side authorization.
  • A file or web page supplies malicious instructions that outrank the intended policy.

How PromptGuard Scan fits the workflow

PromptGuard Scan supports ChatGPT security testing as part of a broader LLM security workflow, with model-agnostic scan packs and CI-friendly evidence.
