Integrations - SIEM

The Security Information and Event Management (SIEM) integration engine enable tenants to forward event logs in various formats to SIEM platforms or other external systems. Avanan allows integrating with multiple SIEM platforms.

Encryption - Unless configured otherwise, all events are forwarded over HTTPS.

Source IP Address

Avanan can be deployed in one of several geographic regions. The security events get forwarded from a unique static IP for each region.

The static IP address for different regions:

• United States - 34.192.247.192
• Europe - 54.247.106.52
• Australia - 52.63.125.59
• Canada -  35.182.23.24
