Enterprise agents no longer just chat: they call tools, retrieve instructions, and can touch internal systems. When a skill or MCP server comes from outside the organisation, teams need evidence about the source before they let the agent act.

Saspien, developed by Cabranet Digital SL, is a small control point in that capability supply chain. Before execution, it verifies the publisher, checks whether the capability still matches what was declared, and returns a decision your policy can use: allow, review, or deny.

Saspien is deliberately model, runtime and cloud-agnostic. It works alongside whichever model provider an organisation uses, Anthropic, OpenAI or any other, so governance teams get provenance evidence without being tied to a single vendor’s enterprise platform or licensing agreement.
