Where ProjectSPG Intercepts Your Data Flow
Direct AI requests leak customer records and secrets to third-party logs. ProjectSPG intercepts prompts at the edge so LLMs only ever see anonymous tokens.
[PERSON_1],
[SSN_1]
1. How Data Leaks
Prompts sent directly to OpenAI, Anthropic, or Google carry customer PII, keys, and financials that get permanently logged and ingested into training sets.
2. Where ProjectSPG Sits
ProjectSPG sits inline as an ultra-low latency (<20ms) reverse proxy at the edge. Just change your API base URL to api.projectspg.info.
3. How It Stops It
We replace private data with mathematical tokens before requests leave your network, then seamlessly rehydrate original values when the LLM replies.
Enterprise Security in Six Core Layers
Everything your security, legal, and engineering teams need to deploy LLMs and autonomous agents with complete privacy.
Automatic Data Redaction
Instantly strips customer names, passwords, credit cards, and confidential records before prompts leave your network.
Context-Preserving Masking
Replaces sensitive items with smart placeholders so AI stays accurate, then restores original values on output.
Zero-Retention Routing
Prompts and keys live only in volatile RAM for milliseconds. Never written to disk, stored in databases, or trained on.
Drop-in BYOK Proxy
Connect directly with OpenAI, Anthropic, Gemini, Mistral, and Groq with your accounts and zero token markup.
Turnkey Compliance
Automated turnkey guardrails mapping directly to HIPAA Title II, GDPR Art. 9, PCI-DSS v4.0, and CCPA out of the box.
Tamper-Proof Audit Trails
Cryptographic SHA-256 event fingerprints and real-time SIEM streaming to Datadog, Splunk, and CloudWatch.
