2T Security delivers Cross Domain Secure Mobility services that allow sensitive mobile operations to function safely and securely—even in environments classified as SECRET. Whether you’re operating in defence, intelligence, law enforcement, or critical national infrastructure, we design, build and support secure-by-design mobile solutions aligned with NCSC patterns and shaped by years of frontline experience.
Our designs are already used to support mission-critical mobility in high-threat environments, underpinned by the UK’s formal guidance on Advanced Mobile Solutions (AMS)—a framework we helped shape alongside NCSC.
We co-designed the Advanced Mobile Solutions (AMS) architecture on behalf of NCSC—experience that now powers secure mobile systems across government and defence.
We build and assure systems using Cross Domain Gateways (CDGs) and hardware-enforced segmentation to safely move data between classifications, securely and intentionally.
To mitigate persistent threats and prevent data leakage, we deploy ephemeral environments with rigorous data modelling, minimising the risk of compromise.
