PromptGuard

PromptGuard is the enterprise-grade AI security platform designed to protect your large language model applications from critical, AI-specific threats. Functioning as a high-performance API endpoint, it instantly blocks advanced prompt injection attacks, prevents sensitive data leakage (PII/secrets), and enforces essential AI agent guardrails. This solution is indispensable for developers and engineering teams deploying production-ready, scalable, and compliant AI experiences across any domain.

Key Features

PromptGuard sits between your application and the LLM provider, providing comprehensive security and performance optimization without requiring complex code changes.

• 🛡️ Prompt Injection and Jailbreak Defense: Leverage ML-powered detection to analyze and block advanced prompt injection and jailbreak attempts in real-time. This capability ensures your model’s core instructions and safety parameters cannot be overridden or manipulated by malicious user inputs.
• 🔒 PII Detection and Data Leak Prevention (DLP): Automatically scans both incoming prompts and outgoing responses to detect and redact sensitive PII (Personally Identifiable Information), including credit card numbers and PHI. This prevents accidental data exfiltration and helps maintain critical compliance standards like HIPAA and GDPR.
• 🤖 Comprehensive AI Agent Guardrails: Provides specialized, granular security for autonomous agents. PromptGuard validates tool calls before execution, detects privilege escalation attempts, and monitors agent behavior for anomalies in real-time, guaranteeing safe and controlled automation.
• ⚡ Smart Caching and Cost Reduction: Optimize your operational efficiency by utilizing semantic response caching, which cuts redundant LLM calls. The built-in AI Memory System intelligently retrieves long-term context, reducing token costs by up to 90% while adding minimal latency overhead (typically under 50ms).

Use Cases

PromptGuard provides specialized protection tailored to critical AI use cases, ensuring security, compliance, and cost efficiency in production environments.

• Securing Customer Support Bots: Deploy high-volume chatbots that can safely handle sensitive customer inquiries without risking data exposure. PromptGuard enforces response filtering to block harmful advice and utilizes PII auto-redaction to ensure customer data remains protected even during complex interactions.
• Protecting AI Code Assistants: Prevent code injection, block malicious suggestions, and enforce strict access controls for AI coding tools. By validating commands and monitoring repository access, you ensure your assistants operate securely within defined organizational boundaries.
• Hardening RAG Pipelines and Web Scraping: When agents retrieve data from external sources or internal RAG databases, PromptGuard scans the content in real-time. This neutralizes indirect prompt injections and malicious instructions hidden within scraped web content or poisoned documents before they can compromise the LLM’s behavior.

Why Choose PromptGuard?

PromptGuard is engineered for production scale, offering verifiable performance metrics and unparalleled integration flexibility that differentiates it from conventional security solutions.

• Instant, No-Code Integration: Achieve enterprise-grade security within minutes. PromptGuard requires only a base URL change and the addition of an API key header. It functions as a drop-in replacement for any OpenAI-compatible API, ensuring zero vendor lock-in and compatibility with OpenAI, Anthropic, Google, and Azure.
• Exceptional Performance and Reliability: Security should not compromise user experience. PromptGuard operates with negligible friction, adding less than 50ms latency overhead while guaranteeing 99.9% uptime, ensuring your security layer is both robust and performant.
• Built-in Adversarial Testing (Red Team): Accelerate your security validation and compliance efforts. The platform includes a built-in testing suite that allows you to instantly run 20+ attack vectors against your current policies, providing a detailed security grade and actionable vulnerability report.
