Pattern updates are a response to security threats. Smart Protection Network and Smart Protection Server computers download the Smart Scan Pattern file from ActiveUpdate servers. Trend Micro products that support Smart Protection Server computers download Smart Scan Agent Patterns from ActiveUpdate servers.
Endpoints within your intranet download Smart Scan Agent Pattern files from Trend Micro products that support Smart Protection Server computers. External endpoints are endpoints that are outside of the intranet and unable to connect to Smart Protection Server computers or Trend Micro products that support Smart Protection Server computers.
