Product Alert

MDaemon AntiVirus and SecurityGateway™ Users

One of our security technology partners, Cyren, recently announced a rapid liquidation of the company and its products. Cyren's antivirus/malware and antispam technologies are used as additional security layers in our MDaemon Antivirus and SecurityGateway products. Although the Cyren services are currently running and providing updates in our software, we are taking immediate action to replace and/or remove those technologies.

Because of the sense of urgency in the matter, we will be replacing the Cyren Malware Detection (antivirus/malware) as our first priority. A new layer of integrated antivirus and malware detection technology will be added through a strategic relationship with a cybersecurity provider with more than 20 years of industry success and whose email security technology is used by one of the largest email companies in the world. The new solution is currently in beta testing and customers can expect an updated release using this technology in the coming weeks.
 
In conjunction with the replacement of the Cyren Malware Detection, we will be removing Cyren's proprietary Recurrent Pattern Detection, also referred to as Outbreak Protection, (antispam) feature from our software products. We are actively researching and considering viable antispam technologies as suitable additions to the existing antispam mechanisms found in our software products.
 
Once our final beta tests are complete, we will be releasing software updates and instructions to you to obtain the new versions of MDaemon Antivirus and SecurityGateway. We have provided some answers below to the most critical questions you may have.
