Segment and Major Customers Information

Disaggregation of revenue by geography

We conduct business globally and are primarily managed on a geographic basis. Our Chief Executive Officer, who is our chief operating decision maker, reviews financial information presented on a consolidated basis accompanied by information about revenue by geographic region for purposes of allocating resources and evaluating financial performance. We define our regions into United States ("U.S."), Europe, the Middle East, and Africa ("EMEA"), Asia Pacific and Japan ("APAC"), and all remaining geographies (primarily Latin America and Canada) included in Others. There are no segment managers who are held accountable for operations, operating results, and plans for levels, components, or types of products or services below the consolidated unit level. Accordingly, we are considered to be in a single reportable segment and operating unit structure.

Revenue by geographic region based on the billing address is as follows (in thousands):

We generate revenue from sales of our products and related subscriptions and support, cloud subscription and managed services, and professional services. Our product and related subscription and support revenue consists primarily of revenue from the sale of our intelligence-dependent security appliances and software, subscriptions to our Dynamic Threat Intelligence (DTI) updates, and support and maintenance. Our intelligent-dependent security appliances include NX (network security), EX (email security), HX (endpoint security), and FX (file security). Product and related subscription and support also includes our enterprise forensic solutions (PX) network forensics appliance and our central management system (CMS) management appliance. Because these PX and CMS appliances are not dependent on regular threat intelligence updates, revenue is recognized upon shipment. Cloud subscription and managed services consists of revenue from the sale of our cloud-based email security, our Threat Analytics Platform (TAP), our Helix orchestration and automation platform, and our standalone threat intelligence subscriptions. Professional services revenue consists of revenue from the sale of security consulting services, including incident response, compromise and security program assessments, red teaming and training.
