In line with WatchGuard’s commitment to maintain the highest security standards for our customer data, Threat Detection and Response (TDR) will upgrade the TLS certificates used by the Host Sensor and AD Helper. From 26 June 2019, versions of the Host Sensor and AD Helper lower than 5.6.3 will no longer communicate with TDR. To ensure that your Host Sensor and AD Helper continue to function as expected, please upgrade to version 5.6.3 or higher before 26 June 2019.

The Host Sensor is the endpoint component of TDR that enables ThreatSync to detect and respond to malware in near real time. It also provides real-time protection against ransomware with Host Ransomware Prevention.

AD Helper keeps TDR synchronized with your local Active Directory server. Periodic synchronization ensures that hosts you add or remove from your Active Directory domain are also added or removed from TDR. TDR also uses the AD Helper to perform Host Sensor installations over Windows file shares. If your AD Helper does not upgrade to version 5.6.3 or higher, you will lose remote installation and Active Directory synchronization capabilities.

For most users, Host Sensors and AD Helper will have already updated to version 5.6.3 or higher automatically. If you use AD Helper infrequently, make sure you restart it before 26 June 2019 so that it can connect and automatically download and install the update.

To check your Host Sensor and AD Helper version or upgrade manually, follow the instructions in the sections below.
