Maximum control over data, keys, networking, enforcement and evidence.
Sovereign Deployment is designed for organisations that require the Xybern authorisation layer to operate inside customer-controlled or approved infrastructure.
It provides maximum control over data location, networking, encryption, access, charter enforcement and security evidence.
This model is intended for highly regulated, sovereign and mission-critical environments where autonomous AI cannot depend on an external security boundary.
With Sovereign Deployment, Xybern can be positioned within the customer's own infrastructure architecture.
The organisation retains control over where critical components operate and where sensitive security evidence is stored.
Depending on the supported deployment architecture, this may include customer-controlled private cloud, sovereign cloud, dedicated infrastructure or other approved environments.
The deployment can be designed so the customer controls:
This allows Xybern to function as part of the organisation's internal security control plane.
Authorisation decisions can be evaluated close to the systems being protected. The enforcement path can remain inside the customer's security boundary.
This reduces dependence on external infrastructure for high-stakes authorisation decisions.
Sovereign Deployment is designed for environments where agents may interact with:
Multi-agent systems can operate while preserving strict authority boundaries. Xybern validates every delegation to ensure:
External and partner agents can be introduced into the customer's environment without automatically inheriting trust. The organisation applies its own Xybern charters to determine:
The customer's security charter remains authoritative regardless of who built the external agent.
Sovereign environments can place Xybern between agents and internal MCP infrastructure. Charters can control:
MCP provides capability. Xybern determines authority.
Authorisation evidence can remain inside customer-controlled infrastructure. For each protected action, Xybern can preserve evidence including:
This provides a defensible record of why an autonomous action was permitted or prevented.
Xybern can form part of the customer's broader cybersecurity ecosystem. Relevant integrations may include:
This allows agentic authorisation events to become part of the organisation's existing security operations.
Sovereign Deployment suits organisations whose security layer must remain within infrastructure they own or directly govern.
Sovereign Deployment is for organisations where the security layer controlling autonomous AI must remain within an infrastructure boundary they own or directly govern.
Your infrastructure. Your charters. Your authority. Xybern provides the enforcement layer.
Run the Xybern enforcement layer within infrastructure you own or directly govern.
Every model enforces the same authorisation, delegation, MCP, approval and provenance controls. What changes is where Xybern runs, and who controls the data and the keys.
