Powering Secure Messages for the Financial Industry

Symphony had built a platform trusted by over 510,000 users across 340 companies to handle sensitive financial communications — and they needed to keep it that way. When Symphony acquired a company specializing in identity management, the technical integration became an immediate priority. The acquired product needed to be woven into Symphony's existing codebase without disrupting the platform that financial institutions were already depending on for over 60 million messages a month. The work required engineers who could move quickly, work closely with Symphony's own product and engineering leadership, and maintain the security standards the financial industry demands.

Admios worked directly with Symphony's product owner and engineering team lead to scope the engagement and assemble the right team. Within weeks, a pod of four Admios engineers — two frontend, two backend — was embedded into Symphony's development workflow.

Over an 11-month engagement the team delivered four major workstreams: integration of the acquired identity management system into the Symphony codebase, a two-factor authentication implementation, a new chat application feature, and a notification system. The team also contributed to QA throughout, treating quality as part of the build process rather than a gate at the end.

The stack centered on JavaScript and React on the frontend, with Backbone.js supporting the existing codebase architecture. Engineers worked within Symphony's existing processes and standards from day one, functioning as a natural extension of the internal team rather than an external vendor.

The identity management integration shipped successfully, giving Symphony's customers new security capabilities that strengthened the platform's position in a regulated industry where trust is the product. The two-factor authentication rollout added a meaningful layer of protection for users accessing sensitive financial communications. New notification and chat features addressed customer feature requests that had been on the roadmap, accelerating delivery without pulling Symphony's internal team off their core priorities.

Symphony gained new functionality, improved security infrastructure, and a faster path to feature delivery — without the overhead of expanding their full-time headcount for a defined-scope project.
