Company Profile

Aston Stone is a UK-based cyber security and Microsoft 365 consultancy supporting organisations delivering into UK Government, public sector, NHS, and other regulated environments. We help organisations achieve and maintain assurance requirements including Cyber Essentials, Cyber Essentials Plus, and ISO 27001, and support compliance programmes such as the Defence Cyber Certification (DCC) and Cybersecurity Maturity Model Certification (CMMC), with a practical focus on staying audit-ready so contracts aren’t delayed by supplier assurance demands.
We bring deep technical expertise across Microsoft 365, enabling us to architect, implement, support, and troubleshoot secure tenant configurations end-to-end. Our delivery spans Entra ID, Intune, Microsoft Defender, and Microsoft Purview—covering identity and access management, device compliance and endpoint hardening, security posture improvement, and data classification and governance.
We also provide technical project and programme management to ensure work lands safely in live environments: clear scoping, stakeholder alignment, practical plans, RAID management, delivery governance, and measurable outcomes. Where required, we act as a Project Integrator (PI)—coordinating suppliers and internal teams, managing dependencies, and driving delivery across security, IT, and compliance workstreams. We deliver secure, evidence-led improvements that stand up to real-world operations and external assurance.
