Symphony supplies the communication systems around financial transactions: messaging between firms, Cloud9 trader voice, counterparty directories and analytics. Its relevance to a broker runs from sales conversations and dealer contact discovery to resolving post-trade exceptions. The product choice is therefore a combination of communication channels, workflow integrations and information controls, rather than a conventional brokerage account.[1][7]
Services & customers
Sections ↑The platform serves financial institutions and their trading, operations, compliance and technology teams. For post-trade work, Symphony describes a connected process: find the appropriate counterparty, open a conversation within the operating application, share the exception context and resolve it with the other firm. The benefit depends on participating counterparties and the systems connected to that workflow.[7]
The main service families
| Service | Documented role and users |
|---|---|
| Symphony Messaging | Internal and cross-firm chat, rooms and workflow automation for financial professionals. Role-based administration, information barriers and expression filters govern communication; bots and applications can bring operating tasks into a conversation.Source 2 |
| Federation | Connects business users to WhatsApp, SMS, WeChat, LINE and mobile-voice channels, with capture and retention features. It extends the communications workflow to clients using consumer applications.Source 3 |
| Cloud9 | SaaS trader voice for brokers, traders and support desks, with intercom, external lines, recording and optional desk hardware.Source 4 |
| Enhanced Directory | Firm-provided organizational and contact data, classified by matters such as function, asset class and geography. Visibility entitlements control which counterparties can see particular contacts and groups.Source 5 |
| Analytics and AI Studio | Communication insights and tools for building and deploying AI agents. Advertised uses include summaries, action extraction and research workflows; access, model support and additional licensing are product-specific.Source 6Source 21 |
Cloud9 user tiers
| Tier | Published distinguishing features |
|---|---|
| Ambient | One speaker channel for sharing desk activity, with Citrix VDI compatibility.Source 4 |
| Desk | Adds internal intercom, up to 600 connections, broadcast audio, multiple devices, free seating, call metadata and an internal directory.Source 4 |
| Trader | Adds external connectivity, a global directory, group broadcasts and more than 50 speaker channels. The stated 600 connection maximum is shared across ringdown and intercom; it is not 600 of each.Source 4 |
Cloud9 Mobile extends desktop voice to an iPhone, including transfer of audio and notifications when a user leaves the desk. Mobile users remain managed through the Cloud9 Admin Portal. On the checked product page, the iPhone download is available and Google Play is marked as forthcoming; pricing and activation go through the account manager.[19]
Platforms & integrations
Sections ↑Symphony publishes separate developer resources for messaging, voice, directory and analytics. These are distinct integration surfaces: embedding a chat window, connecting two messaging networks and creating a bot have different deployment and permission requirements. A documented integration does not mean every feature is included in every subscription.[11]
Connection methods and named workflows
| Connection | How it is used |
|---|---|
| Embedded Mode | Places Symphony conversations inside another application or portal. Published examples include NatWest Agile Markets and Citi Velocity for client communication, and DTCC CTM and Broadridge NYFIX Matching for post-trade collaboration.Source 8 |
| Microsoft Teams | Symphony within Teams gives users access to external contacts and Federation channels from Teams. The separate Chat Interoperability option connects Symphony users to internal colleagues on Teams and supports escalation to video.Source 9 |
| Messaging APIs | The REST reference covers Pod, Agent, Key Manager, DLP, audit trail, malware scanning and Groups. Agent and authentication URLs depend on the customer deployment; on-premises components can use endpoints different from the hosted pod.Source 18 |
| Cloud9 APIs | The public developer entry point provides authentication and role-based API-key guidance. Voice integration needs its own access configuration; a messaging bot credential is not presented as a universal credential for every Symphony product.Source 28 |
| Voice archives | Recordings and transcripts can remain in Cloud9 infrastructure or be transported to a chosen archival provider. Symphony names NICE, Verint and ASC among its archive partners.Source 20 |
| Directory in operating systems | The Enhanced Directory page identifies an Aladdin integration combining contact discovery and bespoke bots for reconciliation workflows. Firm-maintained contacts and access entitlements remain part of the directory design.Source 5 |
Custom development is also available from Symphony’s professional-services team. Its examples include broadcast tools, connection imports and a data-extraction bot that sends selected-room content as JSON to a configured destination. These examples describe commissioned workflow capabilities, not a promise that the same bot is installed automatically for every customer.[26]
Pricing & commercial terms
Sections ↑Current product and developer pages describe service tiers without publishing a complete numerical subscription tariff. The commercial specification needs to identify the voice tier, embedded application, mobile access, AI add-ons, implementation work and archive integrations required.[4][17]
Published commercial distinctions
| Item | Terms visible in the public material |
|---|---|
| Embedded Mode plans | Workflow includes collaboration mode and additional interaction controls. Custom adds features such as third-party extension apps and custom theming. Basic is restricted to legacy ECM customers until renewal. No currency rates are shown.Source 17 |
| Embedded application scope | A Partner ID is issued after contracting and is specific to the agreed platform/use case and approved domains. Testing with that ID in UAT exposes the purchased feature set.Source 17 |
| Cloud9 Mobile | The product page directs customers to their account manager for pricing and access; the app download does not establish that mobile use is included without charge.Source 19 |
| AI agents | The developer guide describes AI Agent as an add-on that may require additional licensing and must be enabled for the customer environment.Source 21 |
| Microsoft Teams | Symphony expressly says that it does not supply a Microsoft Teams licence. The integration uses the customer’s existing Teams environment.Source 9 |
| Professional services | Messaging engagements can be a one-off build, a project or continuing support. The published description provides a scoping and proposal process, without a universal implementation price.Source 26 |
Implementation & delivery
Sections ↑Key management is a substantive deployment choice. Symphony’s current cloud plans distinguish customer-dedicated keys from customer-owned key management, and standard-cloud operation from Confidential Cloud. The appropriate architecture depends on the firm’s control requirements and the contracted service.[10]
Published managed-cloud options
| Plan | Hosting and key-management scope |
|---|---|
| Standard | Symphony manages services in its standard cloud with customer-dedicated keys, including the key manager and API agent.Source 10 |
| Plus | Services remain in the standard cloud with customer-owned key management; the plan adds standard-cloud DLP.Source 10 |
| Advanced | Services are managed by Symphony within Confidential Cloud, with customer-owned key management and Confidential Cloud export, API-agent and DLP components.Source 10 |
Implementation work described by Symphony
| Workstream | Practical scope |
|---|---|
| Voice rollout | Agree project requirements and milestones, configure the environment, validate it, train users and provide go-live assistance. The delivery timetable depends on organizational size and complexity.Source 25 |
| Existing voice infrastructure | Coordinate carriers, recording vendors, SSO and downstream systems; the migration service includes reviewing private-wire circuits and moving relevant connections to SIP network-to-network infrastructure.Source 25 |
| Workflow development | Messaging professional services moves from discovery and a detailed proposal through development, deployment and support. Bespoke integrations and agent projects can form part of that engagement.Source 26 |
| Developer preparation | Registration in the developer training program provides sandbox credentials and a bot account. Public resources include API documentation, training and developer certification; this is separate from production-user provisioning.Source 11 |
For embedded deployments, application domains and the agreed use case matter as much as the visual integration. A change of host domain requires coordination with Symphony. This makes the test environment, purchased feature set and intended production location useful acceptance criteria before rollout.[17]
Support & contacts
Sections ↑The voice professional-services page advertises standard 24/7/365 support. Its enhanced Client Delivery service adds a named manager, monthly reviews and escalation coordination for strategic customers. The separate help article publishes regional telephone coverage in GMT; those hours should be read as regional desk windows, not substituted for a negotiated response-time commitment.[25][16]
Published contact and support routes
Scope Published in the Federation help material; also consult the firm’s internal IT team or technical account manager.
Scope US direct and Canada; the US/Americas toll-free number is +1 866-753-4239.
Hours Published US desk window:12:30–00:00 GMT.
Scope Product and administrator resources; feature availability can depend on organization settings.
Permissions & service scope
Sections ↑Symphony’s regulatory disclaimer states that it is not a broker-dealer, introducing broker or trading venue, and that it performs no execution, clearing or settlement function. Where customers negotiate financial instruments using its services, the published terms describe bilateral negotiation between those customers. The customer remains responsible for the rules applicable to its activity. Compliance-oriented communication features therefore do not confer financial authorisation on the customer or create a retail trading-protection arrangement.[12]
Security and operational controls
| Area | Published control and evidential scope |
|---|---|
| Identity and access | The security page documents SAML 2.0 SSO, including named integrations with Duo, Okta, OneLogin and Microsoft Entra ID. The legal security measures separately require MFA for access to Symphony’s production environment.Source 14Source 15 |
| Data protection | Symphony publishes TLS 1.2 for data in transit and AES 256 for stored customer data. Messaging also uses end-to-end encryption and customer key-management arrangements; the selected deployment determines which components the customer operates.Source 14Source 2Source 18 |
| Continuity | The legal measures describe encrypted backups held separately from primary storage and a business-continuity/disaster-recovery plan. The inspected material does not provide a universal numerical recovery-time or recovery-point commitment.Source 15 |
| Assurance | Symphony states that it has achieved SOC 2 and ISO certifications. This profile does not infer certification scope, validity dates or customer compliance from those general website statements.Source 14 |
The published security measures describe support responses based on incident severity and tracking through resolution, without disclosing the complete response schedule. Product advertising about continuity and compliance should therefore be paired with the service-specific agreement, archive arrangements and operational responsibilities established for the deployment.[15]
Operator & evidence
Sections ↑The legal data-processing document identifies Symphony Communication Services, LLC, or the applicable affiliate, as the service-agreement party. Its current version is dated 1 April 2026. The corporate history records a 2014 founding by a financial-institution consortium and Ben Chrnelich becoming CEO in 2026.[13][1]
How the current product family developed
| Period | Documented development |
|---|---|
| 2021 | Cloud9 and StreetLinx were acquired, adding trader-voice and counterparty-directory capabilities.Source 1 |
| 2022 | The acquisition of Amenity Analytics provided the foundation for the Analytics platform and its language-processing capabilities.Source 1 |
| Current published reach | The Messaging page reports more than 500,000 users across 1,400 institutions. These are Symphony’s published network figures, not an independently audited count of active users.Source 2 |
The contact page lists offices in New York, London, Singapore, Belfast, Hong Kong, Paris, Pennington, Sophia Antipolis, Stockholm and Tokyo. These locations describe the operating footprint; the contract still determines which legal entity supplies a particular customer’s services.[27][13]

Additional Information
Sections ↑Records, channel behaviour and exit
| Operating point | Documented detail |
|---|---|
| Message export | Administrators can export messaging, events and room data in Symphony XML, Actiance or EML formats. Recurring exports default to 24-hour periods; ad-hoc date-range exports are also supported. Wait for the export job to finish before collecting it, and do not run ad-hoc and recurring exports together.Source 23 |
| WhatsApp response window | In the documented Federation workflow, delivery depends on the contact having replied within the previous 24 hours. Outside that window, messages queue until a new reply opens another window; the interface distinguishes Active and Pending contacts.Source 24 |
| Voice transcription | Published language support covers English, French and Japanese, with other languages subject to enquiry. Symphony says voice data is not used for model training without explicit agreement. Transcription can extract trade details, but that feature is not evidence of automatic trade execution.Source 20Source 12 |
| Recording oversight | The Reconciliation Dashboard flags recording discrepancies and exports reports; support can investigate gaps. The page does not promise recovery of every missing recording.Source 4 |
| Return or deletion | The DPA provides for customer-elected return or deletion of personal data after service termination, subject to the agreement. Legal retention and protected backup copies are exceptions; it is not an unconditional immediate purge of every record.Source 13 |
The detailed AI documentation narrows some of the broad language on the Analytics product page. It is especially useful for separating an available tenant feature from a development path that is still described as forthcoming. The following limits are the published state checked on 21 October 2026.[6]
AI access and current implementation limits
| Area | Published scope |
|---|---|
| Authority and visibility | Agents use on-behalf-of access and cannot obtain more Symphony data than the requesting user. Room membership, information barriers and sharing restrictions apply. An agent’s linked app must be installed for that user.Source 21 |
| Studio activation | Symphony must enable AI Agent Studio for the tenant and an administrator must install it for the user. The documented default is one created agent per user; a change requires discussion with the account or technical account manager.Source 22 |
| Models and external tools | Studio documents supported Google Gemini models. Customer-selected or self-hosted model connections remain marked forthcoming. Remote MCP connections currently support non-personal API-key tokens; OAuth and personal-token authentication are not yet supported.Source 22 |
| Development roadmap | The AI Agent guide still labels its custom API-first development path as forthcoming. Studio’s own Messaging tool is also labelled forthcoming. These labels should remain visible when evaluating broader marketing about custom agents and model choice.Source 21Source 22 |
