Red Team Testing

The Red Team API lets you test your PromptGuard security configuration against a library of adversarial prompts. Use it to validate your presets, identify blind spots, and measure block rates before deploying to production.

The Red Team API requires admin/internal access. Contact [email protected] for access.

Why Red Team?

Before deploying AI security to production, you need to know:

Block rate: What percentage of attacks does your configuration stop?
False negatives: Which attack types slip through?
Confidence calibration: Are confidence scores reliable?
Preset comparison: Which preset works best for your use case?

Interpreting Results

Block Rate Benchmarks

Block Rate	Assessment	Action
> 90%	Good	Configuration is strong
70-90%	Warning	Review allowed tests and tighten rules
< 70%	Critical	Upgrade preset strictness or add custom rules

Confidence Score Guide

Confidence	Meaning
> 0.85	High confidence detection
0.6 - 0.85	Moderate confidence — may need rule tuning
< 0.6	Low confidence — consider adjusting thresholds

Best Practices

Test before deploying — Run the full suite against your preset before going to production
Compare presets — Run the same tests against different presets to find the best fit
Test regularly — Re-run after changing presets or custom policies
Use custom prompts — Test with prompts specific to your domain and user base
Monitor the allowed tests — Focus on understanding why certain attacks weren’t blocked
