Supporting the environments that support national security

Defence organisations operate within some of the most demanding environments in the world. From military bases and training facilities to secure operational sites, these environments must function reliably at all times.

The defence environment

Defence estates are complex, high-security environments where reliability and operational readiness are essential. Facilities must support a wide range of activities including training, logistics, accommodation, operational planning and equipment maintenance.

Maintaining these environments requires services delivered with strong operational discipline, technical expertise and security awareness. ISS works alongside defence organisations to ensure these environments remain resilient and fit for purpose.
