We’re excited to share the latest updates across both CiraSync and CiraHub—designed to give IT admins greater flexibility, tighter control, and more options when it comes to syncing contacts and calendars across platforms. Whether you’re managing guest users, integrating external data sources, or optimizing emergency communication workflows, these new features are here to simplify and strengthen your organization’s data sync strategy.
CiraSync Updates
Predefined “All Guests” List for Collections and GAL Tunnels
By popular demand, CiraSync now includes a predefined “All Guests” contact list that can be used in Collections and Global Address List (GAL) tunnels. This update eliminates the need to manually identify or tag guest accounts—saving admins valuable time and significantly reducing the risk of sync errors.
What Is a Guest Account?
A guest account is created for users outside your organization who need access to Microsoft 365 resources such as Teams, SharePoint, or Outlook. These identities are managed in Microsoft Entra ID (formerly Azure Active Directory) and are labeled as “Guest” users. With this new predefined list, keeping guest contacts in sync has never been easier.
CiraSync Hub Connector : How to Create a Sync Tunnel from CiraHub on CiraSync
If a data source is not directly by CiraSync but is supported by CiraHub, you can still synchronize its data to user mailboxes by configuring CiraSync to perform a one-way sync from the CiraHub hub.
In addition to offering a wider range of sourcing options, the CiraHub-CiraSync connector also supports custom data mapping and advanced filtering capabilities.
CiraHub Updates
Filter Contacts by Organizational Unit (OU) in Google Workspace
CiraHub now supports contact filtering by Organizational Unit (OU) when syncing from Google Workspace. This feature gives you more granular control, allowing you to sync only the relevant contacts from specific departments, teams, or organizational branches.
Create and Filter by Contact Collections in the Hub
Admins can now create Contact Collections directly within a CiraHub Hub—and use them as filters during synchronization. Whether you’re tagging contacts by department, region, or role, these Collections make it easy to manage and target specific contact groups across systems with precision and flexibility.
New: Everbridge Connector
Keep Emergency and Operational Contact Data Aligned in Real Time
CiraHub now integrates with Everbridge, a critical event management and mass notification platform used by enterprises and government organizations. With this integration, contact information synced through CiraSync can now be seamlessly made available to Everbridge, ensuring accurate and real-time communications during emergencies or critical events. This update is especially beneficial for organizations that rely on Everbridge to deliver urgent alerts to mobile devices, landlines, and email.
Stay in Sync—No Matter Where Your Data Lives
These latest enhancements to CiraSync and CiraHub are designed to help you manage more users, connect more systems, and keep your contact and calendar data in perfect sync—whether it’s for daily productivity or emergency response.
