Railproof | Sovereign Governance Infrastructure
AI without proof is legally and operationally ungovernable.
Every day your organization deploys AI that answers legal questions, analyzes financial risk, and processes patient data. And every day, you lack verifiable proof of what it decided, why it decided it, or what sensitive data it touched.
During a regulatory review or litigation hold, "We trust our model" is not a defensible answer. Railproof is the control plane that sits between your applications and your AI models. It enforces policy in real time, blocks unsafe outputs, and generates cryptographic audit evidence that stands up to an auditor—or a judge.
THE PROBLEM: OBSERVATION IS NOT ENFORCEMENT
AI adoption is accelerating. Regulatory scrutiny is accelerating faster. The gap between those two curves is where institutional risk begins.
Most enterprise AI safety tools are passive. They watch what the AI does and write a log. When an AI invents a case citation, leaks an SSN, or issues an unsanctioned financial recommendation, the compliance team reviews a dashboard that says "Response sent."
Datadog observes. NeMo Guardrails filters. But observation is not enforcement. Logs are not proof.
"Observation tools record the accident. Railproof is designed to stop the accident before it reaches the user."
The moment a potential hallucination, PII leak, or policy violation is detected, Railproof physically intervenes to block the unsafe response from being delivered. The user never sees the compromised output.
ENFORCEMENT IS NOT OBSERVABILITY
Railproof is the only control plane that physically severs the TCP connection mid-stream.
HOW RAILPROOF WORKS
Railproof sits transparently between your applications and your AI models—no code changes, no model rewrites.
Intercept
Every prompt and response passes through Railproof before it moves anywhere.
Scrub & Enforce
Before data leaves your network, Railproof strips PII and blocks unauthorized commands based on your corporate policy.
Verify
The AI's reasoning is evaluated by independent local verification models, flagging inconsistencies and potential hallucinations before delivery.
Record
Every action is cryptographically hashed and chained into an immutable audit ledger—a continuous chain of evidence for your auditors.
THE ARCHITECTURE OF PROOF
Every request passes through 14 deterministic enforcement checkpoints before a single byte reaches the user.
| Layer | Checkpoint | What It Does |
|---|---|---|
| L0 | Physics Perimeter | Benford's Law statistical scan detects anomalous numeric outputs (financial manipulation, fabricated data) |
| L0.5 | Prompt Injection Firewall | Two-tier scanner (deterministic regex + local LLM classifier) catches jailbreak attempts before they reach the model |
| L1 | Packet Stream Interception | The TCP connection is live-monitored. A kill signal physically severs the socket mid-stream if a violation is detected |
| L2 | Sovereign Retrieval (RAG) | Context is pulled exclusively from your redacted, air-gapped knowledge vault—not the open web |
| L3 | Deterministic Redactor | PII (SSNs, names, contract parties) is mathematically stripped and replaced with cryptographic tokens before egress |
| L3.5 | Residual Safety Verification | A second local model re-scans the redacted output for any PII that escaped the deterministic pass |
| L4 | Agentic Tool Registry | Agents are restricted to a sovereign allowlist of approved APIs and databases—no arbitrary tool execution |
| L4.5 | Consensus Jury | Two independent local models (Meta + Microsoft) must score the output as stable—eliminating shared alignment bias |
| L5 | Reasoning Integrity Verification | Output is cross-referenced against sovereign context to detect hallucinated facts, ghost citations, or jurisdiction mismatches |
| L6 | Immutable Proof Hash | Every decision is SHA-256 hashed and chained to the previous record—a tamper-evident, court-admissible ledger |
| L8 | Asymmetric Governance Keys | Policy changes require your RSA private key signature. Vendors and developers cannot override your posture |
| L9 | SIEM Threat Interceptor | Every security event is written to the sovereign threat log and broadcast to your SOC in real time |
| L10 | Economic Cost Cap | Daily spend limits per tenant auto-route traffic from cloud to local models—preventing runaway AI bills |
| L11 | Air-Gap Sovereign Mode | In strict mode, all outbound cloud requests are hard-blocked at the transport layer. Zero data leaves your perimeter |
THE OPERATING SYSTEM FOR GOVERNABLE AI
Railproof collapses the complexity of enterprise AI governance into three foundational pillars.
Govern: Reliable Enforcement
Enforce policy consistently across the enterprise.
- The Kill Switch: Instantly pause all AI data flows across the organization to prevent widespread exposure.
- Dual-Key Governance: Safety thresholds require cryptographic authorization to change—preventing unauthorized overrides by developers or vendors.
- Domain-Specific Enforcement: Sector-aware redaction and policy rules for Finance, Legal, Healthcare, and General contexts—not a one-size-fits-all filter.
Prove: Cryptographic Evidence
Create verifiable audit trails for every decision.
- The Immutable Proof Ledger: Every AI decision, redacted token, and enforcement event is SHA-256 hashed and chained. Download an automated Regulatory Submission Pack to prove the exact AI reasoning path to any auditor.
- Forensic Discovery: Our agentic engine builds a verifiable, hop-by-hop chain of evidence across your archived data—not a keyword search, a cryptographically receipted investigation.
- Targeted Data Erasure: Remove an individual's data from the AI's active context instantly, without model retraining, to support GDPR Right to Be Forgotten compliance.
Control: Predictable Costs
Own your AI infrastructure while managing costs.
- Economic Governance: Per-department daily budget caps with automatic failover to local models when cloud limits are reached.
- 35ms Semantic Caching: Verified answers to repeated queries are served from a high-speed cache—bypassing the LLM entirely.
- Tiered Intelligence Routing: High-volume, simple tasks route to fast local models; complex analysis routes to cloud. Cost-appropriate execution at every layer.
FORENSIC DISCOVERY: THE CAPABILITY NO COMPETITOR HAS
Railproof's Agentic Discovery Engine works like a forensic investigator, not a search engine.
"Project Falcon contractors" → Found: Master Service Agreement → Extracted: [ENTITY_ORG_44] (Acme Corp).chain_root → hop_1_hash (0x9a8b...) → hop_2_hash (0x4c2d...) → chain_head (0xe7f8...)
BUILT FOR THE ENTERPRISE. GOVERNED BY YOU.
| 🛡️ For the CISO / CRO | 📋 For the CCO | ⚙️ For the VP of Engineering |
|---|---|---|
| "I need to prove our AI never exposed data—and I need to stop it before it does." | "My auditor is asking what the AI decided last quarter. I need a signed, defensible answer." | "I need to control AI costs, prevent runaway spend, and stop explaining AI failures." |
| Kill Switch. Dual-Key Governance. Real-time interception. | Automated Regulatory Submission Pack. Full chain-of-custody. | Budget caps. Local model failover. 35ms Semantic caching. |
BATTLE-TESTED: REDUCING RISK IN THE REAL WORLD
Legal: Ghost Precedent
The Threat: An AI-assisted brief cites a case that doesn't exist. The brief is filed.
The Railproof Fix: The L5 checkpoint detects the hallucination, strips the response before the attorney sees it, and logs the event to the proof ledger.
Finance: Unauthorized Trade
The Threat: An AI agent issues an unsanctioned "BUY" recommendation to a customer.
The Railproof Fix: L4 Agentic Tool Registry and L0 Physics Perimeter intercept the directive. The action is blocked and escalated to SIEM.
Healthcare: PHI Leak to Cloud
The Threat: AI Medical Scribe sends patient SSNs upstream to a cloud summarization API.
The Railproof Fix: L3 Deterministic Redactor strips SSNs before egress. Cloud model receives a secure cryptographic token.
RAILPROOF vs. THE LEGACY AI STACK
Railproof does not replace your existing AI tools. It wraps them at the infrastructure layer.
| Legacy AI Tools (Observability) | Railproof Sovereign Infrastructure |
|---|---|
| Observe failures after they occur | Prevent failures by blocking them before delivery |
| Best-effort safety relying on prompts | 14-point deterministic enforcement on every request |
| Trust developers with simple config files | Enforce governance requiring cryptographic authorization |
| Basic logs that can be altered or lost | SHA-256 chained ledger—immutable and court-admissible |
| Unpredictable cloud costs | Economic control via smart routing and caching |
| One-shot RAG retrieval | Multi-hop forensic discovery with cryptographic receipts |

If your AI can't prove what it decided, why it decided it, and that it never touched data it wasn't supposed to—you are one audit away from a serious problem.
