Working Above OFFICIAL

Secure Infrastructure for Secret & Top-Secret Environments

Our Working Above OFFICIAL Service delivers highly assured infrastructure, rigorously vetted personnel, and uncompromising security controls for environments operating at Secret and Top-Secret classifications. Designed for systems where compromise could cause serious or exceptionally grave damage, this service protects national security and mission-critical operations through isolated platforms, certified high-assurance solutions, and sovereign UK-controlled hosting.

We provide a fully assured operating environment for classified workloads, including air-gapped networks physically isolated from the internet, NCSC-approved cryptography protecting data at rest and in transit, and operations delivered within List X and accredited secure facilities. This is reinforced by TEMPEST shielding, tamper-evident material handling, and approved secure destruction of classified waste.

All work is carried out by SC or DV-cleared personnel under strict need-to-know access controls, with advanced auditing and forensic logging of every user action. Secure information sharing is enabled through high-assurance HardSec cross-domain solutions, allowing data to be shared and visualised between Secret and Top-Secret systems without compromising isolation.
