Why SharePoint for Financial Services Now
SEC Rule 17a-4 modernization took effect in June 2023. This regulation significantly impacts how financial services manage documents. Prior to 2023, electronic recordkeeping required WORM (Write Once, Read Many) storage. This type of storage was typically provided by vendors like:
- Vendor A
- Vendor B
- Vendor C
- Smarsh
- Global Relay
- Mimecast
The 17a-4 modernization has updated WORM-only requirements to focus on audit-trail-based records. Now, Microsoft 365 and Microsoft Purview Audit Premium can meet these new standards for the first time.
When combined with NYDFS 23 NYCRR 500 cybersecurity controls and FFIEC IT Examination expectations, the SharePoint Online and Purview combination offers:
- A robust platform for financial services document management.
- Enhanced compliance with regulatory standards.
- Improved security and audit capabilities.
EPC Group's FSI SharePoint practice has successfully delivered books-and-records implementations for various financial institutions. These include:
- Regional banks
- Broker-dealers
- Registered Investment Advisors (RIAs)
- Asset managers
- Hedge funds
- Life and Property & Casualty (P&C) insurance carriers
We have a unique advantage due to our deep expertise with the SharePoint platform. Errin O'Connor was part of the original SharePoint 2003 beta team. He is also a 4× Microsoft Press SharePoint author.
Furthermore, our role as Lead Architect at the Federal Reserve Bank of New York distinguishes us in the industry.
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 apply to SharePoint sites and OneDrive sharing. EPC Group creates IB segmentation for various scenarios, including:
- 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 are layered for enhanced security. These include:
- Customer Key encryption: Tenant-managed keys.
- Microsoft Purview sensitivity labels: Double Key Encryption (DKE) for the highest sensitivity.
- Restricted SharePoint Search: Prevents MNPI sites from being indexed.
- Defender for Cloud Apps: Real-time controls to prevent MNPI downloads to unmanaged devices.
- Insider Risk Management: Monitors 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
