Catch partial leaks
Real attacks often extract fragments, rules, or behavioral hints before full disclosure. ZeroLeaks classifies leaks from hints to complete extraction.
Prompt Extraction
Prompt leakage defense
Test whether your system prompt can be extracted
ZeroLeaks probes for direct, partial, and inferred disclosure of hidden instructions so teams can protect proprietary prompts and internal operating logic.
Direct and indirect extraction probes
Leak-depth scoring from hints to complete disclosure
Prompt hardening recommendations
Protect more than prompt text
The scan looks for exposed tool schemas, routing logic, retrieval rules, copyright policies, and operational constraints that attackers can use to escalate.
Harden prompts with evidence
Findings include the attack path and remediation guidance so teams can reduce leakage without breaking useful assistant behavior.
FAQ
Is system prompt extraction still a real risk?
Yes. Even when full prompts are protected, partial disclosure can reveal internal logic, tool access, and guardrail rules that help attackers go deeper.
Does ZeroLeaks store my system prompt?
System prompts are processed transiently for scans. Reports store findings and metadata, not full prompt copies.
