Case Study: a UK mobile network operator achieves TSA compliance with NCC Group

Achieving TSA compliance for a UK mobile operator Responding with confidence to Ofcom under the UK’s Telecommunications Security Act

A UK mobile network operator faced an urgent request from Ofcom under the Telecommunications Security Act (TSA). The operator lacked in-house TSA expertise and had received inadequate prior consultancy advice, risking a response that would fall short of regulatory expectations and potentially lead to penalties. They engaged NCC Group for its specialist telecommunications security services to confidently address the challenge.

NCC Group led collaborative workshops with the operator's teams to compile a robust, evidence-based response. The solution from NCC Group successfully met all of Ofcom's requirements and deadlines, allowing the client to avoid penalties and reputational damage. The engagement also resulted in a remediation roadmap, and NCC Group is providing ongoing support to strengthen the operator's long-term TSA compliance and cyber resilience.
