Why role-based access control is the foundation of deal trust
How RBAC prevents information leakage, enforces privilege, and creates the documented evidence trail that regulators and courts expect.
Why role-based access control is not optional
In an M&A process, information is asymmetrically sensitive. Salary data must not be visible to advisors who may work on future competitive processes. Privileged communications must not be accessible to AI systems or non-legal personnel. The target company's financial data must not be visible to the target's own employees until permitted. A document uploaded by the AML Advisor must not be readable by the Deal Associate before the lead counsel has reviewed it.
All of these requirements can only be satisfied by a deal platform with granular, role-based access control implemented at the infrastructure level — not as a checkbox in a settings panel.
The 11 roles in a properly structured deal
| Role | Tier | Key visibility constraints |
|---|---|---|
| Deal Owner (VP Corp Dev) | 1 | Full access. Override authority (2-person required). |
| General Counsel | 1 | Full access + privilege partition. Only role that can mark documents privileged. |
| CFO | 1 | Financial + compliance exposure. No salary data from target. |
| CHRO | 1 | Salary data (target + acquirer). No financial exposure data. |
| Integration Lead | 2 | 100-day plan + synergy data. No salary, no compliance exposure. |
| AML Advisor | 2 | AML guardrails only. No financial data, no salary, no privilege. |
| Tech Advisor | 2 | Technical DD only. No financial, HR, or legal data. |
| Deal Associate | 2 | Read + upload only. Cannot delete or mark privileged. |
| Local Counsel (jurisdiction) | 2 | Own jurisdiction guardrails only. |
| Auditor | 2 | Read-only audit chain. No deal actions possible. |
| Target (portal) | 3 | What buyer has chosen to share. No buyer financials. |
The privilege partition problem
Legal professional privilege is the most sensitive RBAC requirement in a deal platform. Once a document is marked privileged, it must be excluded from all AI processing, inaccessible to all non-legal personnel, and stored in a partition that cannot be accessed by any user without explicit Lead Counsel authorisation.
Most deal platforms treat privilege as a tag — a metadata field that prevents visibility in the main UI. This is insufficient. AI extraction systems that process the entire VDR corpus will have already processed the document before the privilege flag is applied. The only adequate implementation is a separate encrypted partition with privilege flagging as the ingestion trigger, not a post-processing tag.
DealSafi implements privilege partitioning at the infrastructure level: documents routed to the privilege partition are never processed by the AI extraction engine and are stored in a separate S3 bucket with different access policies from the main VDR.
