Theta Lake Selective Archiving enables organizations to capture, archive, and supervise electronic communications from modern collaboration platforms while maintaining regulatory compliance. The solution addresses requirements such as SEC 17a-4, FINRA Rule 3110, FCA's SYSC, and IIROC correspondence rules for financial services institutions. The product allows organizations to selectively archive specific communication modalities, such as in-meeting chat, polling, and whiteboards, without requiring the archiving of voice or video content. This approach enables full feature enablement of collaboration tools while meeting compliance obligations. Organizations can choose to archive content in Theta Lake's SEC 17a-4 compliant storage or integrate with existing archive and eDiscovery systems. The solution uses API-based integrations to capture communications from unified communications and collaboration platforms. The platform provides unified search capabilities across archived communications and supports legal hold functionality. It includes AI and machine learning capabilities for proactive compliance monitoring and risk detection. The system offers conversation replay features with unified views across different communication modalities. Deployment is performed through API integrations that do not require agents, bots, or recording connectors. The solution supports mobile messaging capture and provides real-time compliance advisory capabilities.
