Case Study – Retail and Healthcare
Retail and healthcare chain enhances threat detection and vulnerability management with CTEM
DOWNLOAD THE PDFAbout the client
The client is a major UK-based retail and healthcare chain with tens of thousands of employees. Operating in a highly regulated and complex sector, the organization faced mounting pressure from targeted threat actors and needed to ensure strong detection capabilities across its enterprise.
The client’s challenge
Operating in a threat-rich landscape, the client sought a clearer understanding of their exposure to targeted threat actors, including Turla — a known nation-state adversary.
Their security posture assessment goals included:
- Conducting a comprehensive security assessment across their enterprise
- Evaluating detection coverage against high-priority MITRE ATT&CK techniques
- Identifying exposure to exploitable vulnerabilities (CVEs) used by threat actors
- Correlating findings with threat actor TTPs to inform prioritization
The complexity of their infrastructure and the breadth of threats they faced required a highly customized, threat-informed approach.
Benefits
- Clear visibility of detection gaps – The assessment surfaced multiple high-priority MITRE techniques with insufficient or no detection coverage.
- Threat-aligned detection engineering – Findings enabled prioritized tuning and development of detection content focused on high-risk adversaries like Turla.
- Strategic risk reduction from known CVEs – A critical CVE associated with Turla was found on a small number of assets; another was present across a broad footprint—prompting prioritized remediation.
- Smarter vulnerability management – The client shifted from a CVEs-only model, where they only defended against generic threats, to a threat-informed risk approach, improving triage based on real-world exploitability.
Our solution
CyberProof conducted a comprehensive Continuous Threat Exposure Management (CTEM) assessment using a four-phase, intelligence-led methodology:
- Threat Modeling – Developed a tailored threat profile with emphasis on adversaries relevant to retail and healthcare, such as Turla.
- Data Ingestion and Inventory Analysis – Collected and analyzed asset inventory, existing detection configurations, and current vulnerabilities to identify where exposures existed.
- Detection Capability Mapping – Evaluated detection tooling and rules using the MITRE ATT&CK framework to uncover visibility gaps in high-risk techniques.
- Threat Actor TTP Correlation – Correlated known TTPs (e.g., those used by Turla) with detection and vulnerability data to prioritize coverage and remediation.
This structured approach enabled the client to shift from generalized security hygiene to threat-informed defense.
Results
The client now has a roadmap for enhancing its long-term detection engineering, strengthening resilience and exposure management across the business. They have prioritized the tuning of their detection content to target specific adversaries, identified and remediated critical vulnerabilities, and improved their alignment between their detection capabilities and real-world threats.
