PromptShield — Real-Time Defense for AI Agents

Block prompt injection, jailbreaks, and data leaks before they compromise your AI workflows.

Prompt Injection is the New SQL Injection

AI agents can be manipulated by malicious prompts hidden in emails, documents, or API responses. These attacks can bypass guardrails, leak sensitive data, and execute unauthorized actions — often without user awareness. Traditional security tools can’t parse AI logic or block prompt exploits in real time.

What is PromptShield?

PromptShield is DefendAI’s AI-native, bi-directional prompt firewall. It inspects and sanitizes every input and output, enforces enterprise policies, and learns from live incidents to stop evolving threats.
