Defence and government organisations cannot use public cloud for their most sensitive systems. DSEC OS provides hosting on hardware you physically control, with mandatory security enforcement at every layer and full supply chain transparency.
For defence and government workloads, the cloud provider itself is part of the threat model. Their employees, their infrastructure, their jurisdiction — each introduces risk that cannot be mitigated by configuration alone.
DSEC OS is deployed on hardware you own, in facilities you control, under your jurisdiction. The platform operates entirely self-contained. Air-gapped deployment is supported for environments that require complete network isolation from the public internet.
DSEC OS does not offer a "permissive mode." Security controls are mandatory and enforced at the kernel level. Every container workload is confined by SELinux type enforcement policies, AppArmor profiles, and eBPF-based network policy — regardless of what the container image itself is configured to do.
The platform is built on Rocky Linux 9.x with CIS Level 2 benchmarks applied. Kernel parameters are tuned for security, unnecessary services are stripped, and cryptographic policies are enforced system-wide.
Government and defence environments require that every action is attributable and every event is recorded. DSEC OS maintains an immutable, append-only audit journal that cannot be silently modified or deleted — not even by administrators.
The audit system captures privilege use, access control decisions, container lifecycle events, configuration changes, and network policy enforcement — providing the complete forensic trail required for security investigations and compliance reporting.
If your organisation requires sovereign, air-gap-capable hosting infrastructure with mandatory security enforcement, we'd like to hear from you. We work with a small number of clients and give each engagement the attention it deserves.
