The role:

The Information Security Leader role is pivotal to Defence’s ability to safeguard sensitive information and maintain operational integrity. Recent high‑profile cyber incidents have placed MOD information security under intense scrutiny from Ministers, the Cabinet Office, media and the public. Defence identified strengthening Data Loss Prevention (DLP) and Automated Classification controls as critical actions, to mitigate such risks.

You’ll be responsible for the strategic direction, implementation and continuous improvement of Defence’s information security tooling, with a particular emphasis on DLP across MODNET. By leading the development and optimisation of technical controls and policies, you’ll ensure Defence data is proactively protected, risks are mitigated, and robust incident response capabilities are in place. You’ll enable rapid rule design, testing and deployment, making secure practices seamless and proactive, minimising the impact of incidents by alerting stakeholders to new risks.

Effective leadership in this area directly supports MOD’s resilience, protects sensitive information, and avoids significant un‑forecast costs, thereby safeguarding operational integrity and public trust.

You’ll lead a small, technical team, being responsible for designing how the team operates and grows, working seamlessly with the other operational and incidents teams across the MOD.

• Lead the development, deployment and optimisation of DLP and security tooling across MODNET.
• Collaborate with MOD, Government and industry partners, to align tooling and policies with best practice.
• Cohere the development, deployment and optimisation of DLP and security tooling, across Microsoft tenants within Defence.
• Manage, lead and mentor the Information Security team, supporting professional development, upskilling and performance.
• Drive continuous improvement and innovation in technical security operations.

We'd expect to see relevant skills and experience in deploying, managing and/or optimising information security tooling, especially Data Loss Prevention solutions and of leading and managing a team. You’ll also need to demonstrate experience of triaging and/or assessing, security or critical incidents (cyber, physical, personnel or information assurance).
