Issue/Introduction

What firewall port must be open for sensor to server communication?

Environment

  • EDR Server: All Versions
  • EDR Sensor: All Versions

Resolution

To establish sensor to server communications port 443 is required to be open for sensor to server communication 

Additional Information

  • Communication default protocol is HTTPS
  • 443 is default and configurable (on-premise systems) to utilize a different port
  • Communication does not need to be bi-directional. The sensor initiates¬†communicates with the server and the server only responds
  • All upgrades package, live response, and group changes happen at sensor check-in where the server will respond with the new info that the sensor will take back.¬†
