How We Protect Your Contracts When AI Analyzes Them
Clear, human-readable transparency about how our AI contract review works, why your data remains 100% confidential, and why we never train public AI models on your private agreements.
Zero AI Model Training
Your contracts, NDAs, and uploaded documents are never used to train, retrain, or fine-tune public AI models.
Bank-Grade Encryption
All data is shielded with TLS 1.3 encryption in transit and AES-256 encryption at rest inside isolated, SOC-compliant cloud enclaves.
Human in the Loop
AI assists and clarifies — it never makes legal commitments for you. You retain 100% final control over signing and executing agreements.
What Happens When You Upload a Contract?
We believe you shouldn't need a computer science degree or a cybersecurity certification to understand how your legal documents are processed. Here is the step-by-step lifecycle of your document:
Encrypted Ingestion
Your contract PDF or DOCX is uploaded over a TLS 1.3 encrypted tunnel directly into your private, tenant-isolated cloud vault.
Isolated Analysis
Text is securely parsed within an isolated enterprise LLM container with zero data retention and strict confidentiality boundaries.
Instant Report Delivery
Clauses, risks, and plain-English summaries are generated and sent straight to your browser session.
Ephemeral Memory Wipe
Once analysis finishes, temporary LLM processing caches are wiped clean. Only your account retains the encrypted report.
Why Pasting Contracts into Public AI is Dangerous — And How Indigo is Different
Copying sensitive corporate contracts or employee NDAs into consumer AI tools (like free ChatGPT) can cause serious data leaks, breach NDA obligations, and expose trade secrets. Here is how Indigo e-Sign provides safe, enterprise-grade legal AI:
| Security Factor | Indigo e-Sign Enterprise AI | Public Consumer AI Tools (ChatGPT, Claude Free) |
|---|---|---|
| Data Confidentiality & Training | ✅ Strict Zero Training Guarantee: Data is never used to train any model. | ❌ Default opt-in to train future models on your private text. |
| Storage & Encryption | ✅ 256-bit AES + TLS 1.3: Isolated cloud database with encryption keys. | ⚠️ Stored in generic cloud databases with broad employee access. |
| Legal Validity (eSign) | ✅ Built-in ESIGN Act & eIDAS Signatures with SHA-256 audit trails. | ❌ No eSignature capabilities or court-admissible certificates. |
| Contract Hallucination Guardrails | ✅ Document-Grounding Architecture: AI answers only from your specific contract text. | ⚠️ Known to fabricate clause numbers, jurisdiction laws, and dates. |
| Access Control & Roles | ✅ Role-based organizational access & expiring signature links. | ❌ Anyone with login access can view entire chat history. |
Built-In AI Security Guardrails
Our multi-layered defense architecture ensures safe, accurate, and confidential document review.
🛡️ Prompt Injection & Jailbreak Defense
Malicious parties cannot embed hidden instructions inside contract PDFs to manipulate AI verdicts. Our parser sanitizes and isolates all text before analysis.
📑 Document-Grounded Verification
The AI engine is strictly anchored to the text within your uploaded contract. It will never invent terms or cite clauses that do not exist in the agreement.
🔒 Tenant Isolation & Zero Cross-Talk
Every customer account operates within an isolated cryptographic boundary. One company's contracts can never be viewed, indexed, or accessed by another company.
📜 Cryptographic SHA-256 Audit Logs
Every signature event, view timestamp, and IP address is recorded into an immutable audit trail, providing complete chain of custody for court admissibility.
