The AI governance layer
for regulated industries

The LLM reasons. Your systems decide.
Proviguard governs the boundary.

Every LLM tool call intercepted, validated against regulatory requirements, and cryptographically proven before it reaches your decisioning engines, payment rails, or compliance workflows.

The problem

Your LLMs are making calls your compliance team can't prove

When an LLM output feeds a credit decisioning engine, triggers a transaction block, or reaches a BSA officer's filing queue — who governs that handoff? Portkey and LiteLLM give you logs. Logs are not proof.

No cryptographic proof
Logs show what was recorded. A SHA-256 tamper-evident chain proves what happened. Regulators know the difference.
PII leaving your VPC
SSNs and account numbers pass through third-party guardrail providers before reaching the LLM — unprotected and outside your network boundary.
No downstream awareness
Existing gateways govern the LLM call. They don't prove what system received the output or what it did with it.
No regulatory screening
No OFAC SDN or OIG LEIE built in. Generic guardrails don't know what FinCEN, CFPB, or OCC require.
Use cases

Any workflow where LLM output feeds a regulated system

Proviguard governs the boundary between LLMs and consequential systems — wherever that boundary exists. The workflows below are representative examples, not an exhaustive list.

Banking & Fintech
Healthcare Coming soon
Insurance Coming soon
Legal Coming soon
The governing principle: if an LLM's output feeds a system that executes a regulated consequence — a credit decision, a payment, a compliance filing — Proviguard intercepts, validates, and proves the handoff. These workflows are illustrative examples, not an exhaustive list.
Credit
Income & asset extraction — underwriting input
LLM extracts from W-2s, tax returns, bank statements. Output feeds nCino or Zest AI. The LLM does not approve or deny — it extracts. Proviguard governs the handoff.
Fraud
Fraud signal generation — real-time
LLM generates risk signals in <500ms. Output feeds deterministic rules engine. The engine makes the block/allow decision. Proviguard proves the signal was OFAC-clear before arrival.
BSA / AML
SAR narrative drafting — BSA officer review
LLM drafts the narrative. BSA officer reviews, edits, and owns the FinCEN filing. Proviguard blocks any model substitution on regulated output.
AML
AML alert triage — narrative & scoring
LLM drafts alert narrative for analyst review. Analyst makes the SAR/dismiss decision. Mandate records exactly what the LLM produced and when it reached the analyst queue.
Payments
Wire pre-validation — BEC detection
LLM assesses wire instructions for business email compromise indicators and SWIFT anomalies. Compliance officer makes the execution decision.
KYC
KYC document review — onboarding
LLM extracts and validates identity documents against onboarding criteria. PII never leaves the VPC during review.
Reg B
Adverse action letter — Reg B compliance
LLM generates compliant adverse action notices with specific CFPB reason codes. Loan officer reviews before delivery. Mandate proves exactly what letter went to the customer.
AP
Invoice & document extraction — AP automation
LLM extracts structured fields from invoices and purchase orders. PAN and account numbers tokenized before the LLM sees the document.
These are illustrative examples. Any banking or fintech workflow where an LLM's output reaches a decisioning engine, payment rail, compliance system, or regulatory filing is a Proviguard use case. If your compliance team needs to prove what your AI did — this is the infrastructure layer.
Why Proviguard

What no other gateway provides

Cryptographic audit chain
SHA-256 append-only chain across 4 streams. Any modification is mathematically detectable. Portkey gives you logs. Proviguard gives you proof.
VPC-resident PII
Token Vault lives inside your VPC. SSNs and account numbers never leave your network boundary — unlike third-party guardrail integrations that route PII through their own servers.
OFAC screening in-memory
SDN & OIG LEIE screening runs sub-2ms via in-memory radix tree. No external API call. No added latency. No dependency on a third-party provider during the transaction window.
Per-decision failover policy
SAR narratives block on provider failure. Fraud signals fail to same-tier. Dispute assembly gates to a human. Not one policy — the right policy per regulated workflow.
Deployment

Three models. One governance standard.

Cloud SaaS
Fully managed. Connect in hours. Proviguard handles infrastructure, updates, and uptime. No DevOps required.
Best for fintechs and mid-market financial services
Hybrid VPC
Token Vault and GUARD checks run inside your VPC. LLM routing and observability managed by Proviguard. PII never leaves your network boundary.
Best for regional banks and healthcare organizations
Air-gapped Enterprise
Full on-premise deployment. No external network calls. Fully auditable infrastructure. Meets the strictest data residency requirements.
Best for large banks and federal financial institutions
Early access
