What begins as a cyber security nightmare ends as a transformation story. This real-life case shows how one retail organisation, with Approach Cyber’s help, turned a ransomware attack into the catalyst for lasting resilience.

True story, anonymised. The details of the journey are factual; we have protected the client’s identity for security and confidentiality.

For over a decade, this mid-sized organisation from the retail sector operated with minimal IT investment. However, in recent years they began to modernise their infrastructure and added basic cyber security measures to stabilise operations and reduce technical debt.

Despite this, the company suffered a major ransomware attack. Critical systems were encrypted, operations were disrupted.

Approach Cyber stepped in at the height of the crisis to stabilise the environment and lead the recovery. Our team worked side by side with the client to:

  • Contain the ransomware outbreak and restore systems and data
  • Conduct a post-incident analysis to identify root causes and close immediate security gaps.
  • Implement 24/7 monitoring and advanced threat detection, backed by our skilled Security Operations Centre (SOC).
  • Develop a practical long-term cyber security roadmap aligned with the client’s growth objectives.

As a result, this combination of emergency response and strategic planning not only neutralised the immediate threat but also laid the foundation for a resilient security posture. It was clear that ad-hoc fixes and entry-level protections were no longer enough to safeguard the business.

With systems restored and new controls in place, the organization quickly moved from a reactive stance to a proactive, risk-based approach. Continuous monitoring now ensures faster detection and response, and leadership has a clear, realistic plan for future investments.

Today, the client views Approach Cyber not merely as a service provider, but as a trusted partner in safeguarding their digital future. The ransomware attack, once a crisis, became the catalyst for a lasting cyber security transformation.
