Vandis, a technology reseller in New York specializing in security solutions and infrastructure services, effectively utilizes Elastic's commercial products to enhance their operational efficiency and customer service. By integrating tools like Shield for security, Watcher for alerting, and Marvel for monitoring, Vandis is able to rapidly identify and address issues within customer networks, often before the clients themselves are aware of any problems. The integration with PagerDuty ensures that their team is notified of any events at any time, facilitating prompt response and resolution. An example highlighted is when Elasticsearch's speed in parsing logs allowed Vandis to inform a client of a network issue before the client's network operations center did. The use of these tools not only supports Vandis's technical operations but also demonstrates the value and efficiency of Elastic's solutions to their customers, resulting in strengthened client relationships and improved security management.
