The AppGate SDP system provides geo location information which is used both in the system claims and in the Audit logs. To achieve this AppGate SDP includes GeoLite2 data created by MaxMind, available from http://www.maxmind.com.
The accuracy if the geo information is only as good as the underlying database. Information is published periodically estimating this by region: https://www.maxmind.com/en/geoip2-city-database-accuracy.
One of the drivers of accuracy is how often the database is updated. AppGate SDP uses the Free Downloadable Databases which are updated monthly.
When Geoip updates enabled under settings --> global settings the appliances may show a warning saying the "Geoip Database was not updated x days ago" this is because the appliances failed to download latest updates from maxmind.
In order to resolve the warning you need to ssh into each appliance showing the warning (one at a time) and follow below steps.

1. SSH into appliance
2. Switch to root: sudo su (if you logged in as cz user you can be root also)
3. cd /etc/cron.daily/
4. you will see a script called: geoIpDbUpdate
6. Run the script: ./geoIpDbUpdate

You need to make sure port 443 outbound allowed to below ip's to get updates from.
Access should be allowed to:
Name: updates.maxmind.com
See https://dev.maxmind.com/maxmind-server-ip-addresses for more information.
Once the script executed successfully the warning will go away.
