Direct GCC and GCC High support
Connect regulated Microsoft 365 tenants without a separate or reduced Sigora feature set.
GCC & GCC High
Email signature management built for GCC and GCC High
Manage and enforce Microsoft 365 email signatures server-side, without Outlook add-ins or endpoint agents. Choose a Sigora-managed deployment or fully Self-Host Sigora inside customer-controlled infrastructure.
Direct support for regulated Microsoft 365
- Multiple connected Commercial, GCC, and GCC High tenants in one deployment.
- The same Sigora features and base per-user pricing.
- No additional per-tenant licensing charge.
- Managed and Self-Hosted deployment.
- Microsoft 365 DoD available for technical evaluation.
Why Sigora
A signature platform that does not force GCC High mail through another vendor's cloud
GCC High organizations get the same administrative product experience while retaining a real choice about where Sigora runs and where signature processing occurs.
No Outlook plugin required
Server-side enforcement avoids client-specific add-ins and endpoint agents.
Customer-controlled deployment
With Self-Hosted Sigora, processing runs in infrastructure your organization controls. Email does not need to traverse Sigora-operated processing systems to receive a signature.
Limited message custody
Message bodies and attachments are not persistently stored during normal processing.
Deployment choice
Keep signature processing inside your existing controlled environment
Cloud-Hosted is the simpler operating model. For organizations handling CUI or other controlled information, Self-Hosted Sigora can operate in customer-controlled infrastructure rather than introducing a separate Sigora-operated message-processing service into the mail path.
Available paths
- Shared Sigora-managed Cloud-Hosted deployment.
- Dedicated Sigora-managed Cloud-Hosted deployment by custom quote.
- Self-Hosted deployment in customer-controlled infrastructure.
- Deployment-specific capacity and resilience planning.
Compliance context
Architecture can support a compliance program. It cannot replace one.
Organizations can connect Commercial and GCC High tenants to the same Sigora deployment while keeping signature processing in customer-controlled infrastructure where needed. Sigora can support a compliance program; your organization remains responsible for scoping, implementing, documenting, assessing, and authorizing its own controls.
CMMC / NIST note: Using Sigora does not by itself make an organization CMMC compliant or satisfy NIST SP 800-171. Product configuration, deployment, surrounding systems, policies, and evidence all remain part of the customer's compliance responsibility.
FedRAMP / GovRAMP note: Self-Hosted Sigora can be deployed inside customer-controlled infrastructure subject to the customer's own scope, controls, and authorization boundary. Sigora is not FedRAMP or GovRAMP certified, and Cloud-Hosted Sigora is not positioned as an authorized FedRAMP or GovRAMP service.
Microsoft 365 DoD note: Microsoft 365 DoD support is available for technical evaluation and is expected to require Self-Hosted deployment. Fit must be confirmed for the specific environment before production use.
