Audit Trail

DueDili maintains a complete, tamper-evident record of every AI interaction with deal data. When deal teams use AI to query data room documents, summarize financials, or analyze contracts, each action is automatically logged with full context—who accessed what, when, and why.

Why Audit Trails Matter in M&A Due Diligence

M&A transactions involve highly confidential information shared under strict NDAs. Comprehensive audit trails serve critical functions:

  • NDA compliance — Demonstrate exactly who accessed target company information and when
  • Post-closing disputes — Trace what information was available to the deal team when representations were made
  • Regulatory inquiries — Provide antitrust regulators or securities authorities with evidence of information barriers
  • Internal governance — Review how deal teams are using AI assistance to ensure appropriate information handling

What Gets Logged

Every AI interaction with deal data captures:

  • Who — The deal team member who initiated the query
  • What — The data room documents, financials, or contracts accessed
  • When — Precise timestamp of the interaction
  • Context — The deal, workstream, and conversation where access occurred
  • Outcome — Whether the query succeeded and what information was returned

Tamper-Evident Integrity

DueDili uses cryptographic chaining to ensure audit records cannot be altered without detection. Each log entry is mathematically linked to the previous entry, creating an unbroken chain that proves:

  • No entries have been deleted
  • No entries have been modified after the fact
  • No entries have been inserted out of sequence

This integrity verification is essential when presenting audit logs to counterparties, regulators, or in litigation. You can demonstrate with certainty that the records accurately reflect what occurred.

Long-Term Preservation

When audit logs reach their retention limit, they are archived before deletion. This preserves the ability to verify the integrity chain historically—critical for responding to post-closing disputes or regulatory inquiries that may arise years after deal close.
