Your trust is our most important asset.
Security by Design
Your Data, Your Tenant
harmon.ie never stores or processes customer data outside Microsoft 365.
All emails, attachments, and metadata handled through harmon.ie are stored exclusively within your organization’s Microsoft 365 or SharePoint tenant, protected by your existing IT policies and compliance controls.Data in Transit
All communication between harmon.ie and Microsoft 365 is encrypted using Transport Layer Security (TLS 1.2 or higher).
No unencrypted data ever leaves your network.
Access Control
harmon.ie fully respects and enforces Microsoft 365 and SharePoint permissions.
Users can access only the information they are authorized to see, and content they do not have permission for is automatically hidden from view (“security trimming”).
Microsoft 365 Consent
harmon.ie uses Microsoft’s secure consent framework to connect to your organization’s data.
When the app is installed, Microsoft displays a permission request showing exactly what harmon.ie can access — only what’s needed to function.
Administrators can pre-approve permissions for the entire organization to simplify deployment.

✔ ISO 27001 certified for information security management
✔ Microsoft 365 App Compliance program for New harmon.ie

✔ Microsoft Trusted Gold Partner and Preferred Content AI
