When firms run both
A common pattern: large financial services firms use Diligent for board portal, entity management, and enterprise audit workflows, and use MCO for financial-services-specific operational compliance (personal trading, gifts, OBAs, surveillance, control room, third-party risk). The two platforms address different buyers (board/legal/audit vs. financial services CCO) and different workloads.
When to choose MCO
-
The firm is in regulated financial services (asset management, wealth, broker-dealer, investment bank, bank, insurance, proprietary trading, private equity, law firm, regulated crypto)
-
The compliance program needs operational depth in personal trading, surveillance, MNPI management, and connected control room workflows
-
Regulatory examinations require consolidated evidence across financial services compliance domains
-
The firm wants one platform covering employee compliance, surveillance, third-party risk, and regulatory obligations
When Diligent may be considered
-
The primary buyer is a general counsel, corporate secretary, board director, or enterprise GRC owner
-
Board management, entity management, or cross-industry audit workflows are deciding requirements
-
Financial-services-specific operational compliance (personal trading, MNPI, eComms review, deal review) is secondary to broader GRC and governance
-
ESG, market intelligence, and compensation data are priorities
