Self-hosted AI Security Gateway

Protect sensitive data before it reaches AI.

PIIProxy detects, masks and blocks sensitive company data before prompts reach OpenAI, Claude, Gemini or other AI providers.

Your prompts never pass through our cloud. The gateway runs inside your infrastructure.

The AI adoption problem

Employees are using AI. Your sensitive data may be going with them.

Developers paste source code. Finance teams paste customer records. HR teams analyze documents. Support teams copy conversations. AI adoption is accelerating faster than corporate data protection policies.

PII Exposure

Customer data

Names, phone numbers, emails, addresses, government identifiers and financial data can accidentally leave company boundaries.

Secret Leakage

Credentials & keys

API keys, tokens, passwords and credentials are often present inside logs, source code and debugging sessions.

Compliance Risk

No central policy

Different teams use different AI providers, making consistent security rules difficult to enforce.

PIIProxy fixes the gap

One security layer between your company and every AI provider.

Your applications connect to PIIProxy instead of connecting directly to an AI provider. The gateway inspects the request, applies company policies, protects sensitive information and then forwards the safe request.

How it works

Protect AI traffic in four steps.

01

Intercept

AI requests go through your internal PIIProxy gateway.

02

Detect

Sensitive information and credentials are identified automatically.

03

Protect

Company policies decide whether data is masked, tokenized or blocked.

04

Restore

Protected placeholders can be safely restored inside your network.

Security without enterprise complexity

Built for companies that want AI without losing control of their data.

PII Detection

Detect names, emails, phone numbers, addresses, IDs, financial data and other sensitive information.

Secret Detection

Prevent API keys, authentication tokens, passwords and credentials from reaching external models.

Reversible Tokenization

Replace sensitive values with temporary placeholders and restore them after the AI response.

Policy Engine

Define different ALLOW, MASK and BLOCK policies for developers, HR, finance and other teams.

Audit Without Content

Monitor security events without storing complete prompts or confidential business content.

Multi-provider

Apply one security policy across OpenAI, Claude, Gemini, Azure OpenAI and future providers.
