Reducing Costs by 94% and Automating Fraud Detection Using AWS with Vocus Group Limited

Every 15 minutes, Vocus’s wholesale network provider sends it a massive amount of data pertaining to mobile calls for its brands Dodo and iPrimus. That data needs to be mediated and sent to Vocus’s billing systems, which verify that customers are receiving bills and being billed accurately for services and inclusions, such as international roaming. Mediating call record data into billing systems is a common practice across global telecom operators.

Before AWS, Vocus mediated call records using costly third-party software that had limited customizations and no fraud detection. Vocus needed a solution that could scale with its growth and reduce development overheads so that it could detect fraud faster and thus provide a better experience for its customers. AWS checked all the boxes.

Using serverless services like Amazon EventBridge, a service for building event-driven applications, Vocus built Mediate Cloud, which ingests, validates, and enriches customer data before passing it to the billing system. After rolling out this solution to Dodo and iPrimus customers, Vocus reduced the cost of mediating call records by 94 percent.

Using services like AWS Lambda, a serverless compute service, Vocus created a solution that uses automation, relies less on human intervention, and improves performance. The company built rules into Mediate Cloud to automate fraud detection, increasing efficiency and reducing the impact on legitimate customers by better targeting actual fraudulent activity. Vocus now runs the rules at set intervals to more quickly identify and address fraud, and it can implement new fraud detection rules 80 percent faster.

“Vocus can create new fraud thresholds and rules within hours that use the same information to detect fraud,” says Peter Beckwith, general manager of technology and analytics at Vocus. “We can continue to provide our customers with excellent service while protecting our business from fraudsters. This gives us more freedom for product design. Using AWS is a true game changer for our business transformation.”

By adopting AWS, Vocus has not only reduced costs and automated fraud detection but has also enhanced its ability to scale and innovate. “The serverless architecture lets us process millions of records effortlessly,” says Issam Kamal, head of architecture at Vocus Consumer. “At the same time, the automation tools help us focus on delivering value to our customers.”

“The scalability and reliability of AWS mean that we no longer have to worry about infrastructure bottlenecks, even as our data volumes grow,” adds Vivek Rajshekar, DevOps manager at Vocus Consumer. “We can quickly turn data into actionable insights, improving everything from fraud detection to the customer experience.”
