The Safety Layer
For AI Agents.
QuiGuard is the self-hosted security proxy that automatically scrubs PII from prompts, responses, and tool calls. Protect sensitive enterprise data before it leaves your network—with zero configuration changes to your AI stack.
What Security Does QuiGuard Provide for AI Agents?
Built for developers. Ready for enterprise compliance. Three core capabilities that close critical AI security gaps.
Prompt & Tool Scrubbing
Redacts PII in user prompts AND Agent tool arguments. The only solution that secures the entire loop—preventing data leaks at the source before reaching external LLMs.
Agent Guardrails
Enforce hard boundaries on AI agent actions. Block dangerous operations (DROP TABLE, rm -rf), prevent data exfiltration to unauthorized domains, and restrict tool usage by policy.
Audit Logs & Compliance Modes
Generate compliance-ready audit trails for SOC 2, GDPR, HIPAA. Switch between Mask, Warn, or Block modes to fit your risk tolerance—with exportable logs for security reviews.
How Does QuiGuard Protect AI Data?
QuiGuard uses a zero-trust proxy architecture to secure data without ever seeing your raw information.
The Zero-Trust Proxy Model
QuiGuard operates as a reverse proxy between your application and any LLM provider. It intercepts all traffic, redacts sensitive data using pattern matching + NLP, enforces policy guardrails, and forwards only sanitized requests—ensuring no PII leaves your controlled environment.
Data Flow: From Prompt to Response
1. User Prompt
"My email is john@secret.com"
2. QuiGuard Scrubs
REDACTS: "My email is <EMAIL_1>"
3. LLM Processes
Receives clean data only
Return Trip: AI replies with placeholder. QuiGuard restores original values before delivery—your data never exposed to third parties.
Self-Hosted (Docker)
- Zero Access: QuiGuard developers cannot see your traffic or logs.
- Local Logs: Audit trails stored on your infrastructure only.
- Full Control: Customize detectors, policies, and retention rules.
Cloud (SaaS)
- In-Memory Only: Prompts processed in RAM and immediately discarded.
- Masked Logs: Events logged (e.g., "Email Detected") but never raw PII values.
- Managed Updates: Automatic security patches and detector improvements.
Live PII Scrubbing Demo
See QuiGuard detect & redact sensitive data in real-time
Try: emails, phones (555-0199), SSNs (123-45-6789), credit cards (4532-1234-5678-9012)
Demo Note: This client-side simulation shows QuiGuard's PII detection patterns. In production, scrubbing happens server-side via the proxy with enterprise-grade NLP, custom regex, and policy enforcement.
Frequently Asked Questions About AI Security
Direct answers to common questions about QuiGuard, AI data protection, and enterprise compliance.
What is QuiGuard?
QuiGuard is a self-hosted AI security proxy that automatically scrubs PII (personally identifiable information) from prompts, responses, and tool calls before data leaves your network. It acts as a zero-trust gatekeeper for AI agent communications.
How does QuiGuard protect AI agent data?
QuiGuard operates as a reverse proxy between your application and LLM providers. It intercepts all traffic, redacts sensitive data using pattern matching and NLP, enforces guardrails on tool usage, and logs audit trails—all without storing your raw data.
Is QuiGuard compliant with GDPR, HIPAA, or SOC 2?
Yes. QuiGuard is designed to help you meet compliance requirements by preventing PII exposure at the source. Self-hosted deployments keep all data and logs within your infrastructure. Cloud deployments process data in-memory only and never store raw PII.
Can I use QuiGuard with any LLM provider?
QuiGuard is provider-agnostic. It works with OpenAI, Anthropic, Google Vertex, Azure OpenAI, and any OpenAI-compatible API endpoint via standard HTTP proxy configuration.
How do I deploy QuiGuard?
Deploy in under 5 minutes using Docker: `docker run -p 3000:3000 QuiGuard/gateway`. Configure your AI application to route requests through `http://localhost:3000`. No code changes required beyond endpoint redirection.
What types of PII does QuiGuard detect and scrub?
QuiGuard detects and redacts emails, phone numbers, credit cards, SSNs, IP addresses, API keys, custom regex patterns, and context-aware entities like names + addresses. Custom detectors can be added via configuration.
Why Security Teams Choose QuiGuard
Before QuiGuard
- PII leaks through AI prompts to third-party LLMs
- No visibility into agent tool usage or data flows
- Manual compliance reviews slow AI adoption
With QuiGuard
- Automatic PII redaction at the network edge
- Real-time audit logs for security & compliance teams
- Deploy in minutes with zero code changes
