  • Industry: Financial services (digital banking)
  • Location: France
  • Challenges: Excessive false positives from static tools, low developer adoption and remediation fatigue, lack of clear prioritization and exploit context
  • Contrast solutions: Contrast Assess
  • Benefits: Fewer false positives, actionable findings developers trust, faster remediation, real adoption across teams

Customer overview 

Fortuneo is one of France’s leading banks. With a fully digital platform, fast release cycles and strict regulatory expectations, the security team needed a way to strengthen application security without overwhelming developers or slowing innovation.

The challenge: Too many alerts, too little adoption 

Three years ago, the Fortuneo security team attended a major French technology event with a clear goal: Find a better way to secure their applications.

Their existing static analysis tools were generating large volumes of findings, but the development teams had stopped engaging with them. Without reliable prioritization or clear exploitability information, developers felt the process was a waste of time and security struggled to get traction on remediation. False positives made it nearly impossible to measure impact, and unresolved vulnerabilities piled up because no one knew where to start.

They were looking for a solution that could bring static and dynamic testing together, automate work and provide reliable findings that developers would actually trust.

Why Fortuneo chose Contrast

When the team evaluated options, Contrast stood out for its ability to reduce noise and surface what truly mattered. The prioritization model, exploit context and clarity of the findings immediately resonated. 

They highlighted several reasons for selecting Contrast:

  • A dramatic decrease in false positives, enabling real prioritization
  • Real-time visibility that helps developers understand issues as they code and test
  • A visual, intuitive interface that makes vulnerabilities easy to explore and reproduce
  • Seamless ticketing through integrated workflows
  • An easier overall experience than the tools they were using before
  • Automation capabilities that fit naturally into their cloud and container-based architecture

One leader summed it up candidly: “Contrast filtered what mattered. The prioritization was clear.

Implementation: Embedded across their environments

Fortuneo built the Contrast agent directly into their base Docker images, ensuring it is automatically present across all development and testing environments. While production environments are excluded for data-sensitivity reasons, nearly all APIs and server-side applications are continuously monitored during development cycles.

Key automation steps include automatic JIRA ticketing, real-time chat notifications of new vulnerabilities, deployment-level coverage statistics and monthly governance reviews that track vulnerabilities by team, criticality and risk exposure.

As they put it: “It is now an obligation that every application includes the Contrast agent.

The results: Fewer vulnerabilities, better focus, real adoption

Fortuneo reports significant improvements for both security and development teams.

They now focus on the vulnerabilities that truly matter rather than wrestling with a backlog of noise. Developers no longer feel like they are wasting time digging through irrelevant results. A new group of developers has emerged as early adopters who actively partner with security and think more about secure coding earlier in the process.

Developers can view vulnerabilities instantly during testing, replay the exact request that triggered the issue, validate their fix immediately and track the lifecycle in JIRA without switching tools. The real-time visibility has been especially impactful.

Security leaders now have stronger governance. Monthly reviews show each team’s risk exposure, progress over time and vulnerabilities requiring action. The organization finally has a structured way to track and reduce application-layer risk.

They also noted that Contrast complements pentesting, bug bounty efforts, cloud posture tools and other scanning tools to give a more complete picture of security.

What Fortuneo says today

“Developers don’t feel like they are wasting time anymore.”

“It was very easy to install and much easier to use than our other tools.”

“We now have fewer vulnerabilities and more focus on the attack surface.”

“Real-time feedback changed everything."
