Deployment Options

Callegra Community is available in two deployment models designed to support both highly secure isolated environments and rapidly deployable hosted environments.

SCIF /Air-gapped Community

Mission-Critical Communications for Secure and Isolated Environments.

Deploy switch-free communications—including voice, video meetings, messaging, and collaboration—inside Sensitive Compartmented Information Facilities (SCIFs), classified environments, and other air-gapped or highly restricted commercial networks.

Callegra Community can be deployed entirely within your organization’s private infrastructure, giving you complete control over data residency, access management, security policies, and communications operations. Designed for defense, government, and security-sensitive organizations, the platform supports isolated and restricted network architectures, including IL5/IL6-aligned environments.

All communications remain fully contained within your network boundary—with no dependence on external telecommunications switching, public cloud infrastructure, or third-party communication routing.

Key Capabilities:

  • Fully deployed within your private or restricted network
  • Supports IL5/IL6-aligned deployment architectures
  • Secure voice, messaging, meetings, and collaboration
  • End-to-end encrypted communications
  • No external telecommunications switching required
  • Administrator-controlled user provisioning and access management
  • Linux-based deployment delivered as a secure OVF image
  • Compatible with existing datacenter and private cloud infrastructure
  • No advertising, tracking, or third-party data exposure
  • Ideal for defense, intelligence, government, and other mission-critical environments

Callegra-Hosted Community

Secure communications without managing the infrastructure.

Callegra Hosted Deployment provides the same secure communications platform in a professionally managed cloud environment operated by Callegra. Organizations can deploy quickly while maintaining enterprise-grade security, end-to-end encryption, and controlled community access.

The hosted model is designed for organizations that want a fast, scalable, and secure deployment without the operational overhead of maintaining on-premises infrastructure.

Key Capabilities:

  • Secure Callegra-managed hosting environment
  • Rapid deployment and simplified administration
  • End-to-end encrypted communications
  • Invite-only gated communities
  • Multi-tenant architecture with controlled access
