A work around you could consider until a fully integration is implemented is setting up email alerts on your Wazuh server.
Prerequisites: Wazuh Dashboard: Administrator rights Lansweeper: Edit Configuration rights or higher Wazuh Server (Low level trouble shooting): SUDO Administrator access
Open Lansweeper configuration, Ticket Content. Add a Security Team or any relevant teams required to be notified, then under ticket type, Add Ticket Type, Name the ticket type (Wazuh SIEM/Security Alert) Complete the rest of the categories as seen fit for your environment. Once Ticket type has been created set the Agent team to the designated Team which was initially created. Further customization can be done as needed for your environment.
While within the Lansweeper configuration navigate to Email Settings, section Ticket Dispatching Add a Rule. Name the rule accordingly, change the conditions field for From Email leave the Equal field, then insert the email address intended to be used for Wazuh Email Alert configuration. Under the actions select Set Ticket Type: Then select the Ticket type category created for Wazuh/Security alerts
Now move to the Wazuh Dashboard, Open the menu list, go to Server Management and click on the drop down list, select settings. From the Settings configuration, select Alerts under Alerts and output management. Go to Email Alerts tab and configure Email alert settings. Under the General tab Define your minimum level of severity you would like the alerts to fire.
Notes: From my experience upgrading your Wazuh environment the ossec configuration file created a new configuration file no longer allowing email alerts to be configured within the Dashboard but still able to configure from (wazuh server)/var/ossec/etc/ file ossec.conf.new At the time of your post you would have had version 4.8/4.9 if current installed at the time of the post. Current version available 4.10 ps, version 4.10 now allows for agent upgrades within the Dashboard rather than having to update via RESTful API and PUT /agents/upgrade command
