Robust Testing: Thoroughly testing your software is essential to identify and eliminate potential issues before they affect users. A study by IBM found that 90% of IT professionals say that system failures have had a significant impact on their business.


4- Fortifying Security: The Bedrock of Financial Software

Security is the cornerstone of financial software. With the ever-present threat of cyberattacks and data breaches, protecting sensitive financial data is of utmost importance. To enhance security and protect this valuable information, consider the following:

Data Encryption: Using strong encryption protocols to protect data at rest and in transit is paramount. Security is not just about preventing breaches; it’s also about maintaining trust. A study by the Ponemon Institute found that the average cost of a data breach in the financial services industry is a substantial $9.41 million.

Access Control: Implementing strict access control measures to ensure only authorised personnel can access sensitive information is fundamental. It’s not just about protecting data; it’s also about meeting regulatory requirements and building customer trust.

Regular Audits: Conducting regular security audits and penetration testing is vital to identify vulnerabilities. A study by IBM found that 62% of financial institutions have experienced a data breach in the past year, highlighting the persistent threat to the financial sector.


The Fexco Case Study

Fexco, established in 1981, is a standout example of a company excelling in financial software development. They process over €14 billion in transactions annually, serving a broad spectrum of financial sectors. Here’s how they achieved their goals:

  • Hiring Stellar Talent

Fexco struggled to find top-notch software professionals in Ireland. To overcome this, they contracted Zartis to assemble an extended development team.

  • Replacing Legacy Software

Fexco aimed to modernise by migrating legacy applications to cloud-based solutions. Zartis helped migrate applications to Microsoft Azure and microservices, resulting in a more flexible and scalable system.

  • Modernising Tech Stack

Investing in modern software applications was a priority. Zartis introduced new technologies, including Golang, Scala, Kubernetes, and Helm, to enhance Fexco’s tech stack.

The Solution: Steps to Success

In 2016, Fexco partnered with Zartis to achieve these business goals with the help of an extended development team. They took the following steps:

  • Modernising the Tech Stack

Zartis initially assembled a team of fullstack developers from Spain. They migrated Fexco’s mature applications to the cloud, utilizing Microsoft Azure and microservices. The new application was written in Java, with Angular for the frontend.

  • Creating a Central API

Zartis defined a software delivery lifecycle and introduced a new architecture and technology stack, accelerating the development of the Central API. This centralisation of data improved efficiency and consistency.
