We are looking for a Cyber Security Analyst – Data Loss Prevention (DLP) to help protect Asda’s sensitive information and strengthen our data security posture. This role will focus on the design, monitoring, and operation of DLP capabilities, with a primary focus on Microsoft Purview and Zscaler platforms.

• Operate and optimise Asda’s DLP tools (Microsoft Purview Information Protection & Zscaler) to detect, investigate, and prevent potential data loss events.
• Monitor DLP alerts, triage and escalate incidents, working with SOC, Legal, HR, and business teams where appropriate.
• Collaborate with business stakeholders to define DLP rules, policies, and exceptions that balance security, usability, and compliance.
• Support integration of DLP with broader security and compliance initiatives (insider risk, governance, monitoring, cloud security).
• Provide recommendations for continuous improvement of data protection controls, coverage, and workflows.
• Develop and maintain playbooks and runbooks for common DLP events and escalation scenarios.
• Produce reporting and metrics on DLP activity, effectiveness, and trends for leadership and governance forums.
• Support awareness and training efforts to embed a strong data protection culture across the business.

• Hands-on experience with Microsoft Purview Information Protection / DLP and Zscaler security tools.
• Knowledge of data protection and insider risk threats, controls, and investigative techniques.
• Understanding of regulatory and contractual requirements for data protection (e.g., GDPR, PCI DSS).
• Familiarity with security operations processes: alert triage, incident response, playbooks.
• Strong analytical and problem-solving skills; ability to interpret DLP events in context of business processes.
• Clear communication skills — able to explain data protection risks and requirements to technical and non-technical stakeholders.

Desirable:

• Microsoft certifications (e.g., SC-400, SC-900, MS-500).
• Experience in large-scale enterprise environments.
• Knowledge of wider Microsoft security stack (Entra , Sentinel, Defender).

• Effective detection and response to data loss attempts across email, endpoint, cloud, and web channels.
• Reduction in false positives and improved precision of DLP controls.
• Stakeholders (Technology, Risk, Legal, HR, Business Units) feel supported and confident in Asda’s ability to protect sensitive information.
• Continuous improvement of DLP capability, aligned with emerging threats and business priorities.

• Be part of a growing Cyber Security function protecting one of the UK’s largest retailers.
• Opportunity to work hands-on with Microsoft’s latest security stack and Zscaler platforms.
• A collaborative and values-led culture with real career growth opportunities.
• Hybrid working, competitive benefits, and the chance to make a real impact for millions of customers and colleagues.

• We are one team: success is shared across Technology, Risk, Operations, Stores, and Supply Chain.
• We are customer-obsessed: keeping customer trust at the centre of our decision-making.
• We are bold and innovative: continuously adapting to protect against new threats.
• We are ethical and transparent: doing the right thing, the right way.
