Job Description
As a Protective Security Assurer, you will play a crucial role in advising and supporting the delivery of a robust security and resilience posture across the NAD Group, industry partners, and the wider Defence community. You will ensure the organisation applies rigorous security and business continuity management processes to protect critical operations and assets across all security classification levels. Your expertise will support the secure delivery of the NAD Group, MOD, and Government projects, working within established policies and governance frameworks to maintain the highest standards of security assurance throughout the project lifecycle.
The UK Government holds vast amounts of sensitive data, financial assets, and personal information that underpin essential public services used by millions. Protecting this information is vital, as threats from organised crime, hacktivists, terrorism, foreign intelligence, and rogue individuals pose significant risks. Your role will be key in defending people, property, and physical assets from damage or loss, helping to maintain public trust and national security.
We seek curious, analytical minds who consider every possibility, ask insightful questions, and dig deeper to uncover risks. You should have a solid understanding of Risk, Mitigation, and Physical Security, alongside working knowledge of Protective Security, Threat Awareness, and Government standards.
On joining, you will undergo comprehensive training including 3-6 months of on-the-job learning and shadowing experienced staff, completion of online NPSA practitioner courses, and attendance at a 3-week Defence Critical National Infrastructure (CNI) course. This role requires a full UK driving licence and frequent travel across UK regions. Your designated permanent duty station will be Abbey Wood in Bristol or Glasgow. Attendance at Bristol will be required for the initial training.
If you are passionate about protecting the nation’s security and want to make a real difference, we encourage you to apply and join a dedicated team committed to excellence in protective security.
For security reasons these roles are open to sole UK nationals only. A ‘sole UK national’ refers to an individual who holds citizenship solely in the UK, without dual citizenship or nationality from another country. We’re unable to offer visa sponsorship.

No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
These roles require you to have lived in the UK for the last 10 years and obtain Developed Vetting (DV) security clearance.

If SC clearance isn’t obtained within 12 months, we reserve the right to withdraw any conditional offer made.
We champion flexible ways of working. Regular in-person attendance is required to promote the benefits of face-to-face collaboration alongside flexibility of hours to support work-life balance and business need.
