Everything You Need to Secure Your AI
Comprehensive protection against prompt attacks, data leakage, and unauthorized access.
Prompt Injection Detection
Real-time analysis using advanced heuristics to detect DAN, jailbreaks, and manipulation attempts.
Jailbreaks & Adversarial Prompts
Techniques designed to bypass safety guardrails. We ensure your model stays within its intended boundaries.
PII Leakage Prevention
Detects when the model is about to expose sensitive data (SSN, medical records, legal case details).
Hallucination Detection Coming Soon
Identifies when the model generates fabricated information, ensuring citations and diagnoses are real.
