Rightside started using the Elastic Stack when it was called the ELK Stack. Before that, data was barely accessible, requests to do historical searches were slow and there were no dashboards nor real-time graphs. With the slow transition of many of their legacy logs into Elasticsearch Rightside ended up with a comprehensive real-time log archive with dashboards using the Elastic Stack and X-Pack Security.
