## Frequently Asked Questions

##### How Do Banks Sync Microsoft 365 Contacts to Employee Phones Securely?

CiraSync connects directly to Microsoft 365 and automatically pushes Global Address List contacts to employee mobile devices, with no end-user action required. Contact data never touches CiraSync’s servers, keeping sensitive information within the bank’s existing Microsoft 365 compliance boundary.

##### Is CiraSync SOC 2 Type II Certified for Financial Services?

Yes, CiraSync is SOC 2 Type II certified, providing financial institutions with independently verified assurance that its security controls meet the sustained standards required for vendor risk management and regulatory due diligence.

##### Does CiraSync Support Certificate-Based Authentication for Banks?

CiraSync integrates with Microsoft Entra ID, allowing banks to enforce their existing authentication policies, including certificate-based authentication, multi-factor authentication, and conditional access, before any administrative access to CiraSync is granted.

##### How Does CiraSync Handle Data Residency for EU Financial Institutions?

CiraSync does not store contact data in its own environment, meaning contact records stay within the bank’s Microsoft 365 tenant and its configured data residency boundaries, supporting GDPR compliance requirements.

##### Can CiraSync Sync Contacts During Bank Mergers and Acquisitions?

CiraSync supports multi-tenant configurations, allowing IT teams to aggregate contacts from multiple Microsoft 365 sources and push a unified directory to employee phones from day one of an integration, with no manual contact management required.
