Email Signature Management Purpose-Built for GCC High and Regulated Microsoft 365 Tenants
Sigora is a compliance-focused email signature platform designed specifically for Microsoft 365 GCC High and regulated environments. Available as both self-hosted and SaaS, Sigora provides centralized signature enforcement without client-side agents or tenant workarounds.
Why GCC High Email Signature Management Requires a Different Architecture
Microsoft 365 GCC High environments operate under different compliance boundaries, mail flow constraints, and vendor limitations than commercial tenants. Many signature platforms designed for Microsoft 365 Commercial do not fully account for these differences.
Sigora was purpose-built to operate within GCC High constraints from day one.
Built for GCC High First
Most signature tools are adapted for GCC High after being designed for commercial tenants. Sigora’s architecture was designed specifically for GCC High mail flow, authentication, and boundary considerations.
Built for Regulated Microsoft 365 Environments
Organizations operating under FedRAMP, NIST 800-53, CMMC, or HIPAA requirements often require infrastructure control and clearly defined data boundaries. Sigora can be deployed in a self-hosted, high-availability configuration within your own environment to support these regulatory and contractual obligations.
Centralized Enforcement Without Client Add-ins
Signature enforcement occurs centrally, eliminating the need for Outlook add-ins, endpoint deployments, or inconsistent client behavior.
Architecture Designed for Regulated Mail Flow
Sigora integrates directly into Microsoft 365 mail flow using a centralized processing model. Signature enforcement occurs server-side, ensuring consistency across clients, devices, and platforms while respecting GCC High boundary requirements.
Centralized Mail Flow Processing
Signatures are applied at the transport layer, ensuring uniform enforcement without reliance on Outlook add-ins or endpoint agents.
High Availability Deployment Model
Self-hosted deployments support multi-node configurations for resilience and controlled failover within your infrastructure.
No Persistent Message Storage
Sigora processes messages in transit and does not retain message bodies, minimizing data exposure and reducing compliance surface area.
TLS & Boundary Awareness
Transport security and tenant boundary considerations are preserved within GCC High and regulated environments.
Technical Evaluation & Deployment Pilot
Sigora offers a structured 60 day evaluation program designed for regulated Microsoft 365 environments. The pilot is deployed within your tenant or infrastructure and includes architecture review, deployment guidance, and validation against your operational requirements.
1. Discovery & Architecture Review
We begin with a technical discussion to understand your tenant type, compliance requirements, and current signature enforcement model.
2. Controlled Pilot Deployment
Sigora is deployed for a defined pilot group, allowing evaluation within production mail flow while maintaining operational control.
3. Review & Rollout Planning
At the conclusion of the pilot, we review results, address compliance questions, and define next steps for full deployment.
No credit card required. Pilot participation is limited to qualified Microsoft 365 environments.
Flexible Deployment for Regulated Environments
Sigora is available as both a managed SaaS platform and a self-hosted deployment model, allowing organizations to align infrastructure decisions with regulatory, contractual, or operational requirements.
