## The panel's verdict

Symphony, a messaging, voice, directory and analytics vendor for global finance, drew converging scores with no substantive disagreement between judges: strongest on integrations and encryption and access, weakest on messaging core, deployment control, governance and discovery and sovereignty. Integrations are the best-documented area — open APIs, custom bots and a named catalogue running from Jira and Salesforce to TradingView, Microsoft Teams interoperability and Zoom. Encryption and access rest on documented SAML 2.0 single sign-on with named identity providers and fully logged least-privilege access; the end-to-end encryption claim appears as a single sentence with no documented key handling or statement of what the vendor can decrypt. For a product positioned on compliance, the bench found no public information on retention configuration, discovery export formats or an administrative audit trail, and none on self-hosting or an exit path — hosting is named as Google Cloud and Amazon Web Services, and data residency, subprocessors and ownership are unknown on the captured pages. No prices appear; pricing transparency reads 0, which the bench treats as normal in this market.

**Speaks for it:**
- Open APIs, custom bots and a named catalogue spanning Jira, Salesforce, TradingView, Microsoft Teams interoperability and Zoom
- SAML 2.0 single sign-on is documented with Duo Security, Okta, OneLogin and Microsoft Entra ID, with all system access logged under least-privilege controls
- Access is revoked within one business day after notification from the manager, with quarterly access reviews
- Federation bridges WhatsApp, SMS, WeChat, LINE and mobile voice into one platform
- The vendor cites 10/10 of the largest global investment banks by revenue and 8/10 of the largest global asset managers by AUM as customers

**Held against it:**
- The bench found no public information on retention policy configuration, legal hold, discovery export formats or an administrative audit trail
- The captured pages describe a cloud-only service on Google Cloud and Amazon Web Services, with no public information on self-hosting or a documented export and exit path
- End-to-end encryption appears as a single sentence, with no public information on key handling, device verification or what the vendor can decrypt
- The bench found no public information on threading, message search across history, file handling or history limits in the core messaging surface
- Data residency, subprocessor exposure, ownership and the contracting entity's jurisdiction are unknown on the captured pages (sovereignty 1-2; the independently computed sovereignty result is 0/10)

**Best for:**
- You work in financial markets and want enterprise messaging with a wide, vendor-maintained integration and bot ecosystem
- Your teams talk to clients on WhatsApp, SMS, WeChat or LINE and need those channels bridged into a compliance-enabled platform
- You already use Duo Security, Okta, OneLogin or Microsoft Entra ID and need SAML 2.0 single sign-on with logged least-privilege access
- You buy through direct enterprise sales and can negotiate retention, export, residency and pricing terms before signing

**Avoid if:**
- You must evaluate retention policies, legal hold and discovery export formats before purchase — the captured pages sell recording and AI-powered summarization but show no administrator-configurable mechanics
- You require self-hosting, a private instance or a documented exit path — the captured pages describe a cloud-only service on Google Cloud and Amazon Web Services
- Your procurement needs a stated data-residency commitment and a subprocessor list — the infrastructure is named as Google Cloud and Amazon Web Services and the sovereignty attributes are all unknown
- Your team depends on documented message search, threading and long-history retrieval — the captured pages show rooms, chats and in-room polls with no public information on search or history limits

## Scores by judge and criterion

### The judges

- **The Team Lead** (v1.0): Runs a distributed team and needs the tool people actually open. Wants threads that stay readable, search that finds last spring's decision, and channels that can be tidied without losing history. Unmoved by feature lists that do not survive a busy Tuesday.
- **The Security Officer** (v1.0): Assumes the archive will one day be read by someone it was not meant for. Wants end-to-end encryption that ordinary users survive, device verification, sessions an admin can revoke, and a plain statement of what the vendor cannot decrypt.
- **The Works Council Advocate** (v1.0): Knows that a chat log is a record of who spoke to whom at what hour. Wants presence a person controls, no individual activity scoring anywhere, retention that deletes rather than hides, and analytics that can be switched off across the organisation.
- **The Compliance Counsel** (v1.0): Will one day have to produce this archive, edits and deletions included, to a regulator or a court. Wants legal hold, an export a lawyer can work from, retention per channel, and an audit trail that survives the admin who made the change.
- **The Platform Engineer** (v1.0): Would rather run it than rent it, and wants to know whether that is a supported deployment or a hobby build. Cares about open protocols, federation, a plugin system with real permissions, and an upgrade path that does not orphan the customisations.
- **The Skeptic** (v1.0): Reads for the message-history cap, the tier where SSO appears, and what "unlimited" excludes. Has seen "end-to-end encrypted" mean direct messages only, on request, with search disabled — and wants that sentence found rather than assumed.
