Framework
Six domains. One unified defense framework.
The PDM is the operational framework that connects every CDA mission, certification, and operator into a coherent system. Six concentric defense layers, from your data at the core to governance at the perimeter.
Six Domains
Each domain represents a layer of defense. Innermost domains protect the data itself. Outer domains govern risk and intelligence.
The vault. What you're protecting.
The innermost layer. DPS protects the data itself: encryption, classification, retention, sovereignty, and data loss prevention. Every other domain exists to protect what lives here.
The walls. Where attackers probe.
The walls. VSD reduces your attack surface through vulnerability management, patch operations, configuration hardening, and continuous surface monitoring.
The garrison. Daily operations.
The garrison. SPH maintains daily security operations: endpoint protection, email security, backup verification, and security hygiene automation.
The gates. Who gets in.
The gates. IAT controls who gets access to what through identity management, authentication, authorization, and zero-trust architecture.
The scouts. What's coming.
The scouts. TID monitors the threat landscape through intelligence feeds, dark web monitoring, threat hunting, and predictive threat analysis.
The command tent. Strategic oversight.
The command tent. RGA provides strategic oversight through risk management, compliance assurance, governance frameworks, and board reporting.
The Metaphor
Each domain corresponds to a layer of a fortified position. From the vault at the center to the command tent overseeing everything.
The vault. What you're protecting.
The walls. Where attackers probe.
The garrison. Daily operations.
The gates. Who gets in.
The scouts. What's coming.
The command tent. Strategic oversight.
