Financial services UC procurement is shaped by regulatory recording obligations under FINRA Rule 3110, SEC Rule 17a-4, MiFID II Article 16, and FCA SYSC 10A, plus heightened controls on cross-border data flows. The ranking below covers UC platforms most commonly selected by banks, asset managers, insurers, and broker-dealers above $5B in assets. Scoring weights compliant recording and archival, integration with surveillance archives such as Theta Lake and Smarsh, identity controls, and the maturity of the vendor's regulated-industry deployment track record.
Financial-services UC procurement turns on three regulatory pillars. The first is compliant recording — voice, video, and chat must be captured, tamper-evident, and retained for the periods required by FINRA, MiFID II, and FCA SYSC 10A. The second is supervisory surveillance — archived communications must be ingestible by Theta Lake, Smarsh, Global Relay, or equivalent platforms. The third is identity, with mandatory MFA, conditional access, and break-glass procedures that map to internal audit expectations.
Buyers should treat the recording connector as a first-class procurement criterion, not an afterthought. The maturity of native recording and the certified-integration depth with surveillance archives is the line where vendors actually separate. Cisco Webex Calling and RingCentral RingEX are the most-deployed combinations at tier-one banks. Microsoft Teams Phone is the preferred choice where Purview already underpins the wider compliance estate, with Theta Lake or Verint completing the surveillance picture.
Communications surveillance scope has widened post-2022 to include chat, video, and screen-share, not just voice. Buyers should validate the platform's coverage across all modalities and confirm retention controls are configurable at the supervisory group level.
