Sector · The ledger never leaves the firm.

Accounting, Tax and Audit

Accounting, tax and audit firms hold unredacted corporate ledgers, bank streams and tax structures for every client on their books, and they want to run modern AI over that decade of data to flag risk and accelerate fieldwork. The cloud is barred because moving those files off-premise creates a cross-border-transfer and third-party-processing exposure that sits directly against ICAEW and FRC confidentiality duties. Mickai brings the whole AI stack in-house, onto hardware the firm owns and under keys the firm holds, so client transactions are analysed inside the building rather than shipped to a vendor. Air-gapped anomaly and audit tooling runs over the full client history locally, which removes the third-party cloud-exposure vector.

The problem and our solution
The buyer

Accounting, tax and audit firms responsible for unredacted corporate ledgers, bank streams and client tax structures.

The problem

Putting that client financial data through cloud AI creates a data-spill and third-party-processing risk that cuts against ICAEW and FRC confidentiality duties.

Our sovereign solution

Mickai runs air-gapped fraud, anomaly and audit analysis over a decade of client transactions on hardware the firm owns, under keys the firm holds.

The value

Faster audits and sharper risk flags with no client ledger ever leaving the firm, which removes the third-party cloud-exposure vector.

The sovereign advantages

These architectural choices support control over the workflows in your deployment. Their benefits depend on configuration, integrations and operating practices. Review external connections, physical security, access and compliance responsibilities together.

Control the processing boundary

Scope inference, extraction, retrieval and storage on infrastructure you control. Document and test any external connector, support channel or transfer before describing a workflow as zero-egress.

Plan for disconnected work

Workflows with local models, data and supporting services can continue offline. Live external email, calendars and other services need an approved connection or controlled import, with clear unavailable and pending states.

Make data location inspectable

Map prompts, documents, indexes, logs and backups to their processing and storage locations. Local hosting supports control of location; access, retention and any transfers still need review.

Use approved company knowledge

Prepare and classify source records, preserve permissions and evaluate answers against the originals. Retrieval and model training are separate choices; agree data use and licences for each.

Budget for the whole service

Compare hardware and licences alongside integration, power, administration, support, updates, evaluation and recovery. Measure cost at the required workload and quality before claiming savings.

Verify access and authority

Define who holds keys, who can administer the system and which actions need approval. Test denied requests, revoked access and audit records. Physical security, insider risk and incident response remain operational responsibilities.

Control change and exit

Agree version selection, signed update procedures, rollback, data export and licence rights. Reassess requirements as software and obligations change; owning hardware does not remove maintenance or compliance work.

Requirements to assess

Review the requirements relevant to your organisation, jurisdiction and intended use with your responsible teams. Cloud services can be appropriate subject to applicable safeguards; on-premise deployment alone does not establish compliance or remove supplier responsibilities.

The lead studios

The enterprise studios that lead in this sector, drawn from the eighteen that sit on the one sovereign substrate. Scope their local processing, operator-held keys and Open Audit Record coverage for the proposed deployment. Confirm availability and any external integrations before relying on a workflow.

Department studio

Audit

Runs the audit workflow over the full client ledger on-premise, surfacing sampling, reconciliation and substantive-testing evidence without the working papers ever leaving the firm.

Department studio

Fraud and Anomaly Detection

Air-gapped fraud and anomaly detection across a decade of client transactions, flagging outliers and suspicious patterns locally rather than streaming bank data to a cloud model.

Department studio

Finance and Accounting

Reads and normalises corporate ledgers, bank streams and tax structures in-house so the figures behind every flag stay inside the building.

Department studio

Compliance and Regulator Mode

Maps the firm's work against ISA (UK), FRC and ICAEW obligations and produces a regulator-ready trail, removing the third-party-processing friction while the firm keeps its own professional duties.

Department studio

Executive BI

Gives partners executive BI over engagement risk, recovery and portfolio exposure drawn only from data already held on the firm's own hardware.

See all eighteen on the sovereign services catalogue.

The opportunity

Audit and assurance firms are under sustained regulatory pressure to raise quality and evidence their judgement at the same time as data-protection counsel restricts what client financial data may be sent to external processors. That tension creates demand for AI that delivers the analytical depth of the cloud while running entirely on infrastructure the firm controls.

The outcome

Measure value, cost and risk on hardware you control.

Faster audits and earlier risk flags from a decade of client transactions analysed locally, the cross-border-transfer and third-party cloud-exposure vector removed while the firm keeps its own confidentiality and professional obligations, and recurring per-seat cloud-AI subscription cost displaced onto hardware the firm already owns.
