When the systems you host support essential services — energy, transport, water, telecommunications — every layer of security matters. DSEC OS provides infrastructure with mandatory defence-in-depth enforcement on hardware you physically control.
Critical infrastructure systems are high-value targets. The standard approach of deploying on general-purpose hosting and hardening after the fact leaves attack surface that shouldn't exist in the first place.
DSEC OS starts from a minimal, hardened baseline. The Rocky Linux kernel is tuned to CIS Level 2 benchmarks. Unnecessary services are removed, not just disabled. Every remaining service runs within mandatory SELinux and AppArmor confinement with the minimum capabilities required.
Traditional network security operates at the perimeter — firewalls and VLANs. Once an attacker is inside the network, lateral movement is often trivial. For critical infrastructure, this model is dangerously insufficient.
DSEC OS uses eBPF-based policy enforcement to control network traffic at the process level. Every container operates in its own network namespace. Egress and ingress policies are enforced per-workload, not per-network. Unauthorised traffic is blocked and logged before it leaves the container.
Critical infrastructure hosting must operate independently of external services. An internet outage shouldn't take down your management plane. A DNS provider's bad day shouldn't affect your control systems.
DSEC OS is fully self-contained. It runs on your hardware with no dependency on cloud services, external APIs, or third-party infrastructure. Air-gapped deployment is supported for environments that require complete isolation from public networks.
If your organisation operates systems that support essential services, and your current hosting infrastructure doesn't meet the security standard those systems demand, we should talk.
