If you have a very small number of offices, a cidr filter per office might work. Or you might try a [translate](https://discuss.elastic.co/t/create-custom-geoip-database-for-logstash-5-2/79473/13) filter. Or, I think, you could [build](https://blog.maxmind.com/2015/09/29/building-your-own-mmdb-database-for-fun-and-profit/) a custom geoip database and use a geoip filter.
