Dear USG/ATP users

Our contract with Cyren on Anti-Spam will be expired on April 30th, after that, Anti-Spam will no longer be functioning if the devices’ firmware version stays prior to ZLD 4.55(ATP series) and ZLD 4.39(USG series).

To be sure that your devices still can provide well protection to your network, please upgrade your device firmware to the latest versions which are applying McAfee solution to provide more comprehensive services.


Suggested firmware version

ATP V4.62


USG V4.62
