Callsign is a cybersecurity startup. They raised a series A of £30 Million to launch their security and authentication engine for banks.
Callsign wanted a user interface design for fraud analysts to design workflows for the AI. After months of trying, their in-house design team got stuck. With the first customer demos coming up, they needed a best in class UX/UI design for workflows- and fast.
The focus of the UX/UI design project with Creative Navy was the policy engine, the tool used by fraud analysts in banks to prescribe behavioural parameters to the AI.
UI Design - Design System
The interface design lets fraud analysts design workflows with ease. The UX concept makes use of only 3 gestures to create workflow elements, to change the node type and to connect the nodes in the workflow.
Collaboration features complete the user experience without distracting from the main task, which is to implement a security policy into an AI workflow.
Enterprise applications tend to have complicated linear user flows. This was the status quo at Callsign.
We redesigned the user flows completely to reflect user needs, rather than the database perspective. In the new user experience, policies are edited in context and users get immediate feedback. There’s no need for an abstract experience when users change what they see and see what they change.
These human centric user flows are the foundation of a consumer grade UX and UI.
In 8 weeks we went from design challenge to a detailed design system. We created a system of UI components where states are documented meticulously. It includes interactions, the principles that stand behind them and different ways of using the UI components in context.
The clear logic and minimalist approach of the page designs coupled with the thorough design system reduced development time by 30%. Thus it became possible for the startup to meet the deadline of the approaching client demos.
Users evaluate workflows in the data visualisation feature. It predicts the likely behaviour of the bank’s security system, given a set of policies.
The user experience is structured into two components. First, a natural language interaction to create the simulation context. Users are familiar with this UX and UI from other parts of the application.
Second, the design of the data visualisation is as simple as can be to provide focus on the essence of the data visualisation outcome. We made this highly abstract feature user-friendly, by reducing cognitive load.
The new design was created in 6 weeks. It covered the design for the workflow creator and for the policy management area. Most of the design was delivered in 4 weeks, including parts of the UI design. Thus, developers started coding the frontend using React and the D3 library. The product demo was ready 4 weeks later.
The success of the demo was instant as major UK banks signed up to use the product. Callsign gained a strong foothold in the market, pleasing investors.
With the design system completed, we organised a handover for their in-house design team. Ever since, they have used the design system for other areas of the Callsign product range.
