A Cyber Security Engineer opportunity for someone with solid experience across the Microsoft 365 security stack (Intune, Defender, Entra, Purview, Copilot) has opened up with an established UK-based organisation looking to strengthen its technical security function. Could this be the role where you put your hands-on security expertise to work across a broad and varied remit, with genuine scope to make an impact?

The organisation holds a range of recognised quality and security accreditations and has a mature approach to IT governance.
