Sigora
What Sigora is
Sigora centrally manages Microsoft 365 email signatures and applies the selected signature server-side after a message is sent. Users continue sending from their usual email clients, without Outlook add-ins or endpoint agents. Administrators can build Base Templates, reusable Modules, and published versions so draft edits do not change live signatures. Published signatures can be assigned to users, Microsoft 365 groups, or domains, and can use Microsoft directory data and configured user, group, or domain attributes. One deployment can manage connected Microsoft 365 Commercial, GCC, and GCC High tenants without an additional per-tenant licensing charge. Customers can choose hosted SigoraOne Cloud or run Sigora Self-Hosted in infrastructure they control. Cloud processes messages in transit and normally does not persistently store message bodies or attachments; Microsoft 365 mail routing to Sigora uses mTLS. Sigora says it can support technical designs for regulated environments, but it does not itself make an organization compliant or place the service within a government authorization boundary. Self-Hosted high-availability setups require customer-provided load balancing and external SQL. The maker offers product-fit, deployment, pricing, and technical evaluation discussions through its contact process.
