Controls & Security

Automation should remove repetitive work—not accountability.

Finance automation must remain understandable, reviewable and owned. Controls are designed into the workflow, not added after it is built.

Control principles

Built around the decisions that still belong to people.

The appropriate controls depend on the process, its financial significance, the systems involved and the organisation's own policies.

Human approval

Material decisions remain with accountable people.

Least-privilege access

Access is limited to what each person and workflow requires.

Exception handling

Unexpected cases follow a defined review and escalation route.

Traceability

Inputs, checks, actions and decisions leave an accessible record.

Monitoring

Failures and performance remain visible to responsible operators.

Documentation

Ownership, operating steps and fallback processes remain understandable.

Operational safeguards

Control extends beyond the happy path.

A useful automation must explain what happens when inputs are incomplete, systems are unavailable or a decision falls outside agreed rules.

Segregation of duties where the process requires it

Data minimisation and appropriate access boundaries

Controlled testing and deployment

Documented change management

Defined fallback processes

Client ownership of critical decisions

Appropriate technology

Use the least complicated technology capable of reliably solving the problem.

Rules-based and deterministic automation is preferred where it is safer and sufficient. Where AI helps interpret unstructured information, defined boundaries and human review remain especially important for financially significant work.
