Microsoft 365 Connector Firewall Requirements
Microsoft 365 Connector Firewall Requirements
The Microsoft 365 Connector requires access to certain URL's via HTTPS port 443 without the traffic being sent via a proxy server.
The table below shows the protocols, ports and URL's that are required for the Microsoft 365 connector to work:
Protocol | Port | From | To |
HTTPS | 443 | Certero Endpoint Server | graph.microsoft.com |
HTTPS | 443 | Certero Endpoint Server | login.microsoftonline.com |
HTTPS | 443 | Certero Endpoint Server | reports.office.com |
Some firewalls only allow IP address ranges to be added rather than the DNS name. The table below shows the protocols, ports and IP address ranges that are required for the Microsoft 365 connector to work:
Protocol | Port | From | To |
HTTPS | 443 | Certero Endpoint Server | 20.190.128.0/18 |
HTTPS | 443 | Certero Endpoint Server | 13.69.128.0/18 |
HTTPS | 443 | Certero Endpoint Server | 40.126.0.0/18 |
HTTPS | 443 | Certero Endpoint Server | 20.166.33.29/18 |
