The compliance gap that opens the moment AI agents start executing financial transactions.

Sidian builds the compliance infrastructure that sits between AI agents and payment rails — so every transaction is assessed, cleared or held, and permanently recorded before any money moves.

Where Sidian sits
The payment networks built the rail. The banks run the trains. Sidian is the signal system.
Pre-execution compliance infrastructure — between every AI instruction and every payment rail.

The Problem

Agentic AI in finance is here.
The compliance infrastructure isn't.

AI agents are now initiating, routing, and executing financial transactions autonomously — at speed and at scale. The compliance tools used by MAS-regulated institutions were designed for humans at keyboards. They were not built for this. The gap between what AI can do and what compliance infrastructure can handle is widening every month.

The Compliance Gap

AI agents are executing financial transactions. No compliance layer exists between their instruction and your payment rail.

When a human initiates a transaction, judgment, mandate awareness, and accountability are implicit. When an AI agent does it, none of those checks exist unless you build them in. Most institutions haven't.

The Regulatory Exposure

MAS FEAT requires explainability. MAS AML/CFT requires audit records. Neither requirement can be met by tools built for human-initiated transactions.

Existing compliance infrastructure was designed for humans at keyboards. It cannot intercept an AI agent's instruction at machine speed, assess it against your institution's own compliance policy, and produce an explainable decision with a permanent record — before any money moves.

The Adoption Paradox

Institutions that don't deploy agentic AI fall behind. Institutions that do deploy it without compliance infrastructure face regulatory exposure.

The solution is not to slow down AI adoption. The solution is purpose-built compliance infrastructure that runs at machine speed — so AI-driven finance can operate with confidence, full accountability, and a complete audit trail.

Guardian SGSV closes this gap.
Purpose-built compliance infrastructure that runs between every AI instruction and your payment rail — assessing compliance, issuing a binding decision, and writing a permanent audit record in milliseconds. Built for MAS-regulated institutions. Available now.

Four things compliance infrastructure must do

Built around one problem.
Solved without compromise.

Agentic AI in finance creates a compliance requirement that existing tools were not designed to meet. Guardian SGSV was.

Pre-execution
Every AI instruction assessed before execution
No AI-generated transaction reaches your payment rail without a compliance decision. Guardian SGSV intercepts every instruction at machine speed and issues a binary outcome — cleared or held — before any money moves.
Audit & record-keeping
A permanent audit record for every decision
Every transaction generates a timestamped, tamper-proof compliance record — rule applied, data evaluated, outcome logged. Seven-year retention. Exportable on demand. Regulator-ready at any time.
Regulatory alignment
MAS FEAT and AML/CFT obligations satisfied
Guardian SGSV produces explainable, auditable AI compliance decisions — satisfying MAS FEAT Accountability requirements and MAS AML/CFT Notice record-keeping obligations from the first transaction.
Deployment speed
In production in weeks, not years
Three integration paths. No changes to your core banking infrastructure. Guardian SGSV is operational before an in-house alternative gets past the design phase — and your MAS obligations start immediately.
When MAS examines your AI transaction records —
Can your institution produce a compliance decision, reason code, and audit record for every AI-initiated transaction? Guardian SGSV makes the answer yes.

Common questions about Sidian and Guardian SGSV

Everything you need to know about Sidian, the Guardian SGSV protocol, MAS compliance, and getting started.

What does Sidian actually do?

Sidian provides compliance infrastructure for financial institutions and businesses using artificial intelligence to initiate financial transactions. Before any AI-driven transaction reaches your payment systems, it passes through Guardian SGSV — Sidian's compliance engine — which runs a comprehensive series of checks covering identity, mandate alignment, financial limits, counterparty screening, escalation rules, biometric confirmation, and permanent record-keeping. Transactions that pass all checks proceed immediately. Those that raise a concern are held for your compliance team to review.
