Use AI Without
Exposing Your Data. Period.
Secure your prompts automatically. Fivo Connect substitutes proprietary code, PII, and financial variables with plausible generic equivalents before they hit public LLMs–”reversing them instantly upon response for zero leak, zero compromise.
Obfuscation & Reversal Pipeline
Analyze how Fivo Connect strips, tokenizes, and reconstructs private data parameters locally.
PII / IP Identification
Identifies names, credentials, keys, database queries, and private code blocks in outbound prompts.
Generic Tokenization
Swaps private data with realistic mock values (e.g. replacing 'Sarah Jenkins' with 'Jane Doe').
Sanitized Transmit
Sends normal-looking data structures to the public model, avoiding filter flags or data storage leaks.
Local Re-Injection
Receives response and instantly swaps mock variables back with original parameters. Perfect outcome locally.
Zero-Leak Protection Safeguards
Ensure total regulatory compliance and absolute IP shielding across all sensitive data classes.
Proprietary Source Code Safeguard
Shields functional algorithms, database structures, and class models. Connect substitutes them for clean generic patterns, maintaining perfect LLM code generation quality.
Plausible Substitution Shield
Swaps your sensitive numbers, variables, and private indexes with realistic, generic dummy values. The AI model is completely oblivious to the protection.
HIPAA-Safe PHI Sanitization
Guards patient names, medical conditions, and SSNs behind plausible, fully compliant fake equivalents, eliminating any risk of regulatory violations.
Secrets & Credentials Lock
Intercepts hardcoded database passwords, API tokens, encryption keys, and environment configs, replacing them with generic sandbox tokens on the fly.
Autonomous Agent Defense
Secures AI agent behaviors by masking file operations, shell parameters, and network targets. Prevents agents from exposing internal network paths.
Automated Round-Trip Reversal
Automatically replaces generic mock variables back to your original parameter indices upon LLM response. Clean final answers, zero manual parsing.

Frequently Asked Questions
Everything you need to know about Fivo Connect.
What is Fivo Connect?
Fivo Connect is a privacy proxy that sits between your application and any public LLM. It identifies and tokenizes sensitive data (PII, PHI, source code, credentials) before it leaves your VPC, then reverses the substitution on the response so your application receives intact data.
Does Fivo Connect handle source code obfuscation?
Yes. Fivo Connect includes AST-based source code obfuscation in addition to PII text detection. It handles proprietary functions, internal API hostnames, database queries, and credential strings. Microsoft Presidio focuses on PII text only.
Is Fivo Connect HIPAA compliant?
Yes. Fivo Connect supports Business Associate Agreements on the Teams and Enterprise tiers. The data flow is fully self-hosted in your VPC, so PHI never touches third-party servers.
What is two-way tokenization?
Fivo Connect replaces sensitive data with generic placeholders before the LLM call (for example, "Sarah Jenkins" becomes "Jane Doe"). The LLM responds using the generic tokens, and Fivo Connect substitutes the original values back in before returning to your application. The LLM never sees the real data, but your app receives the real data back.
How fast is Fivo Connect?
Fivo Connect adds under 50ms P99 latency. The tokenization and reversal happen in your VPC and are optimized for throughput. Most users report no perceptible change in response time.
Can I use Fivo Connect with any LLM?
Yes. Fivo Connect is a drop-in proxy that works with any OpenAI-compatible API, including OpenAI, Anthropic, Mistral, Google, Cohere, and self-hosted models. Change your base URL and it works.
Is Fivo Connect open source?
Fivo Connect has open-source components. The binary is self-hostable with zero dependencies. The managed cloud is a paid tier for teams that want zero ops.
