What Is an Audit Trail?
An audit trail is a chronological record of all activities, changes, and decisions within a system. In governance, it provides the evidence that activities were performed, decisions were made, and controls were operating — enabling reconstruction of events for audits, regulatory examinations, and internal reviews.
What an Audit Trail Contains
A governance audit trail includes: who performed the action (user identity), what was done (action type — create, update, delete, approve), when it happened (timestamp), what changed (before and after values), why it was done (reason, if applicable), and where it was done (system, module, entity). Every governance activity should generate an audit trail entry.
Why Audit Trails Matter
Audit trails serve three purposes: evidence (proving activities were performed), accountability (identifying who did what), and detection (identifying unusual or unauthorized activities). Without audit trails, organizations cannot demonstrate governance to regulators, cannot investigate incidents, and cannot ensure accountability.
Audit Trail vs. Audit
An audit trail is the continuous record of activities; an audit is the periodic examination of those records. Audit trails enable audits — without them, auditors have nothing to examine. MPG generates audit trails automatically for every governance activity, making audits efficient and evidence-based.
How MPG Provides Audit Trails
MPG automatically records every governance activity — entity creation, updates, approvals, status changes, message sends, evidence uploads — with user identity, timestamp, and change details. These audit trails are immutable, searchable, and exportable for regulatory examinations and internal audits.

Frequently Asked Questions
How long should audit trails be retained?
Retention requirements vary by regulation — typically 5-7 years for financial services, though some require longer. MPG retains audit trails indefinitely and they are searchable and exportable at any time.
Can audit trails be modified?
In a well-designed system, no. Audit trails should be immutable — once recorded, they cannot be altered. MPG's audit trails are system-generated and cannot be modified by users.
