Sync Effortlessly

Global Address List

Your employees are connecting on-the-go and in the field, where they need quick access to key contact information.

One source of truth for contact data, with industry leading compliance & security and proven reliability at any scale.

Calendars

While shared calendars are accessible in Outlook, employees also need smartphone access to stay updated. Without immediate access to current shared calendars on their devices, they risk missing important meetings, schedule changes, and emergencies. CiraSync seamlessly syncs these calendars to phones, ensuring employees are always in the loop.

CRMs

CRM licenses are expensive; however, not everyone needs full access to each application. Most employees only need access to contacts. For a fraction of the cost of a Salesforce license, CiraSync can automatically sync contacts to hundreds of employees smartphones.

Integrations

CiraSync integrates with Microsoft 365, Google Workspace and a variety of other platforms to automatically sync contact and people data across directories, shared mailboxes, and mobile devices – keeping information accurate and up to date without manual effort.

Testimonials

Loved by IT Teams and C-Suites Everywhere

CiraSync is the functionality Microsoft 365 should have build in.

“This software is one of those “best things since sliced bread.” We have eliminated probably 12-25 hours a month of somebody doing busywork maintaining contacts to push out to mobile devices.”

Ed H. Senior Network Administrator/ IT

Once it is set up, it flows seamlessly.

“I have used this software across multiple companies. It works well for what it does and solves the issues of having to copy contacts to users’ Outlook profiles. Once it is set up, if flows seamlessly.”

Matthew M. IT Director

CiraSync, always available information, on- or off line.

“CiraSync is our solution to mainly sync contact information to our organization’s iDevices. Rather than depending on a Global address list (which is not really fast in delivering information), CiraSync pushes information, on- or off line. We are happy customers.

Eddy K. Facility Manager & IT
