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.
16-Layer Guardrail System
Our proprietary pipeline analyzes every prompt through 16 distinct security layers in under 20ms.

FAQs
Performance
Will this slow down my application?
No. PromptDefend operates at <20ms latency—imperceptible to end users. Most integrations show zero impact on response time.Integration
How long does implementation take?
16-24 hours for most teams. Python or Node.js? Add two lines of code to your API layer.Compatibility
What models do you support?
PromptDefend works with any provider—OpenAI, Anthropic, Llama, Azure, custom fine-tuned models, RAG systems. We're provider-agnostic.Compliance
What audits do you support?
We're working towards SOC 2, HIPAA, GDPR. Our logs support CFPB & FDA AI/ML guidance readiness.
