A large UK-based Telecoms and MSSP provider with an international footprint. Known for its commitment to innovation and reliability, they continues to shape the future of telecommunications with its cutting-edge solutions and exceptional customer service.
The client had developed and was managing a secure network that connected UK central government departments to each other. For organisations with large, diverse estates, the challenge isn’t just finding vulnerabilities — it’s knowing which ones matter first, which ones are exploitable in real attack paths, and which ones could consume disproportionate time and budget without reducing real risk. This network required stringent security measures and needed to adhere to government standards. The environment consisted of three data centres across the UK, each housing numerous systems. External auditors required evidence of the network’s security.
The client faced challenges in maintaining and demonstrating the required level of security within the dynamic environment. Regular security assessments were necessary for static components, and any significant changes also required assessments. The process of planning, delivering, and managing the findings of these assessments became overwhelming. The project needed a solution to determine what to test, when to test, how to test, and how to effectively consume the assessment findings.
Many environments generate hundreds or thousands of findings — but sheer volume does not equate to actionable insight. Without prioritisation tied to attack paths, business impact, and exploitation likelihood, teams end up firefighting low-value issues while high-impact gaps remain unaddressed.
Our approach to high-volume vulnerability profiles focuses on real-world attack modelling and business impact, not just scoring based on severity labels. Our approached leveraged recognised best practices such as NIST risk-based vulnerability prioritisation and industry data on exploitation patterns. This helped the client distinguish between ‘noise’ and what actually matters.
Our team was engaged to establish a comprehensive vulnerability management programme, which included:
The implementation of the vulnerability management program resulted in significant changes and benefits for both security management and the business:
By reframing vulnerability data through the lens of business impact and identified attack paths, the team was able to allocate resources where they mattered most — reducing real exposure while avoiding wasted effort on findings that had minimal impact on actual risk.
By implementing a robust vulnerability management program, the client achieved a significant improvement in security management and overall business operations. The project demonstrated enhanced compliance with government standards, accelerated remediation timelines, and a more streamlined onboarding process for government clients. The successful outcome not only ensured a secure network but also strengthened the client’s reputation as a trusted provider in the telecoms and MSSP industry.
This engagement exemplifies how structured, impact-driven vulnerability analysis transforms overwhelming data into prioritised action — a critical capability for any organisation facing scale, complexity, and limited security resources.
