合併・買収のためのDay-1対応メッセージング

The first channel bridge is typically live during onboarding, once your Slack/Teams admins approve the app. Unlike traditional domain federation — which can take 4 to 12 weeks because it requires Active Directory trust relationships, DNS modifications, firewall rule changes, and security review on both sides — SyncRivo connects entirely at the application layer through OAuth, so no infrastructure changes are needed in either tenant. Your IT team can initiate the connection from the SyncRivo dashboard with no downtime or maintenance window; the acquired company's admins approve the app on their side. This matters during M&A because business stakeholders typically expect cross-company communication on Day 1, well before any longer-term platform consolidation decision is made.

Yes. SyncRivo provides fully bidirectional sync between Microsoft Teams and Slack — messages sent in a Teams channel appear in the mapped Slack channel in real time, typically within seconds, and vice versa. Threaded replies, @mentions, file attachments, message edits, and message deletions are all preserved across the bridge: a deleted Slack message is also removed from the Teams channel, and a thread reply lands in the correct thread context rather than as a top-level message. Reactions sync with limits: on Teams, reactions appear only for users who connected their account, and Teams supports a small set of reaction types. Messages show the original sender's name and avatar; in Teams channels the post comes from the SyncRivo app with the sender's name, and Slack shows an APP label.

SyncRivo does not run its own DLP or content inspection. Bridged messages are delivered natively to the destination platform, where that platform's DLP and retention policies apply. Message content is not stored on the normal relay path; an optional retry queue temporarily holds undelivered messages. For HIPAA-covered entities, a BAA is available for Enterprise customers. SyncRivo is hosted in the US (Google Cloud us-central1); there is no EU or APAC data residency, and a DPA and sub-processor list are available. SyncRivo does not currently hold a SOC 2 report; we provide a security questionnaire and architecture review on request, plus an activity log and security event history (JSON export).

Bridges can be disabled or deleted from the SyncRivo dashboard with no data-extraction work, because messages already live natively on each platform. As teams migrate in waves, you can keep the bridge running for the channels that still span both platforms and retire each bridge once the last group has moved.

Yes. SyncRivo supports multi-party federation across all five major enterprise messaging platforms simultaneously — Slack, Microsoft Teams, Google Chat, Zoom Team Chat, and Cisco Webex — which is particularly useful for private equity firms managing a portfolio of acquired companies on different chat platforms, or for serial acquirers integrating multiple targets in parallel. You can create dedicated "shared channel" topologies that connect specific teams across tenants — for example, a CFO group spanning four portfolio companies — without opening broad access between organizations or merging directories. Each bridge is scoped to specific channels and managed by owner/admin roles, so a SyncRivo connection between two tenants does not grant any platform-wide access. Bridges between portfolio companies can be added, modified, and retired independently as the portfolio composition changes through new acquisitions or divestitures, without affecting the existing bridges.
