Cyberattacks in the banking industry notably increased. In response, the bank aimed to address this issue by enhancing the security of communications.


Phishing attacks arrived by email

Certain clients received unusual or suspicious emails.


Sensitive documents exchanged via email

Critical documents were exchanged via email, compromising the level of security.


Bank support officers received multiple calls

Clients contacted bank support officers multiple times, diminishing their available time for other important tasks.

How could we create a safer and more convenient way to communicate with the clients?




Secure Messaging LP First Version

At first, we believed that providing email and SMS options would be advantageous for users who have a preference for a particular communication channel.

DSM Version 1

Secure Messaging LP Second Version

After testing, users found no clear distinction between email and messages. Consequently, we focused on messages, which is more consumer-friendly.

DSM Final version

Inbox First Version

The initial version aimed to showcase standard chat functions such as calling and voice recording, but due to time constraints, these features were not prioritized.

DSM Version 1

Inbox Second Version

The second option emphasized UI optimization with smaller avatars, organized threads, enhanced security through encryption for calls, and improved overall UI, including better spacing and a clear send button.

DSM Final version

Create organized discussions

We added threads to organize different client topics, emphasizing them since each client could only have a single support officer. This helps in identifying and addressing specific cases efficiently.

Exchange sensitive information securely

We optimized the document-sharing process, simplifying it for users to send documents while clearly indicating the allowed document types to their support officer.

Responsive Design

This project took precedence over others, and we expanded the feature from the app to the web, ensuring responsiveness for the bank's website.
