By design, Worry-Free Business Security Services can only keep 60-day logs to be queried.

Moreover, if you need logs older than 60 days, it is recommended to subscribe to Log Forwarder API and integrate it with SIEM or syslog tools. This will help as it will collect logs to be managed and archived. Although the logs prior to the setup can no longer be retrieved, the log forwarder can help maintain the logs moving forward.

To enable the log forwarder feature, follow this article: Activating Log Forwarder API in Worry-Free Business Security Services.
