Why SharePoint for Financial Services Now
SEC Rule 17a-4 modernization (effective June 2023+) is the most consequential FSI documents regulation in a generation. Pre-2023, electronic recordkeeping required WORM (Write Once, Read Many) storage — typically vendor-hosted (Smarsh, Global Relay, Mimecast). The 17a-4 modernization replaced WORM-only with audit-trail-based records, which Microsoft 365 + Microsoft Purview Audit Premium can satisfy for the first time. Combined with NYDFS 23 NYCRR 500 cybersecurity controls + FFIEC IT Examination expectations, the SharePoint Online + Purview combo is becoming the dominant FSI document management platform.
EPC Group's FSI SharePoint practice has shipped books-and-records implementations at regional banks, broker-dealers, RIAs, asset managers, hedge funds, and life + P&C insurance carriers. The combination of SharePoint platform depth (Errin O'Connor on the original SharePoint 2003 beta team, 4× Microsoft Press SharePoint author) + Federal Reserve Bank of New York Lead Architect pedigree is the differentiation.
SEC 17a-4 + FINRA 4511 Implementation
EPC Group's 17a-4 + 4511 SharePoint configuration:
- Audit Premium with 10-year retention. All SharePoint + Exchange + Teams + OneDrive access events captured in immutable audit log
- Microsoft Purview retention policies. Per-record-type retention (orders, confirmations, statements, customer correspondence, supervisory records) preventing deletion
- Microsoft Purview eDiscovery Premium. Audit-quality export with tamper-evident metadata, ready for SEC/FINRA examination production
- Documented chain-of-custody. Defensible process documentation for production scenarios
- Customer Lockbox. Microsoft engineer access requires explicit institutional approval
This replaces (or augments) legacy 17a-4 vendors like Smarsh, Global Relay, and Mimecast.
Information Barriers + MNPI
Microsoft 365 Information Barriers (IB) policies extend to SharePoint sites + OneDrive sharing. EPC Group designs IB segmentation: research vs investment banking (Section 15D / Regulation AC), broker-dealer vs RIA (for dual-registrants), trading desk vs back office, lateral partner moves, audit firm independence (for accounting firms).
MNPI controls layered on top: Customer Key encryption (tenant-managed keys), Microsoft Purview sensitivity labels with Double Key Encryption (DKE) for highest-sensitivity, Restricted SharePoint Search preventing MNPI sites from being indexed, Defender for Cloud Apps real-time controls preventing MNPI download to unmanaged devices, Insider Risk Management for exfiltration patterns.
High-Value SharePoint Patterns for FSI
- Deal team workspaces — per-deal sites with dynamic team membership, IB enforcement, conflict screens, post-deal disposition
- Regulatory examination response — per-exam workspaces with examiner Q+A tracking, source-document linking, evidence packs
- WSP + compliance policy libraries — Written Supervisory Procedures, code of ethics, training tracking, attestation workflow
- Board + committee package portals — board minutes, committee charters, materials with secure distribution + audit
- Vendor + due diligence document libraries — third-party risk management (NYDFS Section 500.11) documentation
- Customer due diligence (CDD/EDD) workflow — KYC document collection + review + ongoing monitoring
- M&A due diligence data rooms — internal SharePoint-based data rooms for sell-side advisory + buy-side diligence
