On-Prem
On-Prem & Hybrid Security Architecture
Traditional data-centre security remains critical in hybrid environments. It protects workloads that are not always cloud-native, require tight network zoning, and rely on strong operational controls such as patch management, access management, and physical guardrails.
What it is for
- Hosting business-critical services, legacy applications, and database platforms
- Securing private networks, internal services, and administrative access paths
- Supporting regulated workloads that require physical and logical controls
- Providing edge, data-centre, and hybrid connectivity for centralized governance
Design principles
- Tiered zones with explicit trust boundaries: internet, DMZ, app, data, admin
- Privileged access management and break-glass controls
- Patch, vulnerability, and configuration management as part of lifecycle controls
- Strong logging and detection for internal lateral movement and perimeter changes
