What sigillo delivers

QES & timestamp

Qualified electronic signatures under ZertES (CH) and eIDAS (EU). Timestamping is synchronous; QES is async via Mobile-ID or multi-signer consent.

MCP-native

Streamable HTTP plus legacy bridge. Four tools for AI agents: seal_pdf, seal_status, seal_download, seal_balance.

Swiss stack

Data stays in Switzerland. Infomaniak hosting in Geneva. No reverse tunnel to US clouds.
