Here’s a summary of how HSL Helsinki Region Transport improved its code security and services using GitHub Advanced Security for Azure DevOps, according to the Microsoft customer story:
Background:
  • HSL runs regional transport in the Helsinki area, responsible for about 60% of Finland's public transport journeys, relying heavily on its HSL app for ticket sales.
  • On December 12, 2022, HSL suffered a major cyberattack which completely paralyzed its operations—serving as a wake-up call that its security measures were no longer sufficient.
  • The incident pushed HSL to strengthen its security posture with a focus on “security by design.”
What Changed:
  • HSL’s HSL app was already running on Microsoft Azure.
  • To further boost security, they implemented GitHub Advanced Security for Azure DevOps, with support from Microsoft partner Solita.
  • The solution improved security not just for the HSL app but for all HSL’s current and future applications.
Key Benefits Gained:
  • Greater Visibility:
  • The new tool gives HSL much better insight into code vulnerabilities, making teams more aware and able to better protect their applications.
  • Immediate visibility of security issues (“the visibility will give you pain—but we consider pain as a benefit in this matter,” said Petri Kukko, CISO of HSL).
  • Cultural and Organizational Change:
  • HSL embraced a “security champion model,” designating representatives in various teams to bridge cybersecurity and business, encouragement of sharing knowledge and improving collaboration.
  • About 10 champions hold regular sessions, sharing experiences and best practices.
  • Security by Design:
  • The approach and tools embed security into the development process, making developers “much more secure.”
  • Tools and reporting offer a clear list of vulnerabilities and direct support to resolve them.
  • Faster, More Agile Response:
  • HSL’s developers could see the benefits and results immediately.
  • Adoption of DevSecOps practices became central in their software development.
  • Compliance:
  • HSL handles payment card data and must comply with strict standards like PCI DSS. Microsoft’s tools helped them achieve necessary compliance.
Quotes from HSL Leaders:
  • “All we had done until that point in terms of security was no longer enough. We needed to become more resilient.” – Petri Kukko, CISO.
  • “We needed something that would give us more visibility around code security… that has very much changed now.” – Akseli Wiik, Cyber Security Specialist.
Conclusion:
  • HSL’s transformation is as much about technology as about people and organizational culture. With the right partners and internal champions, HSL believes it’s now in a much stronger, more secure position to serve its millions of customers.
