Erbe has 10 years of experience with e-mail security from Proofpoint. We are convinced that by using Proofpoint’s security solutions, especially through Targeted Attack Protection (TP), we have so far been spared from malware attacks. Thanks to Cyqueo’s competent support, questions were answered immediately, figurations were implemented quickly, and problems were rectified directly. Cyqueo keeps an eye on the configurations of its customers and keeps the products they use up to date. As a result, the maintenance effort for the IT of Erbe was very low

Also, the advice on configuration and constant adjustment is proactively lived by the staff at CYQUEO for us – a real special feature in the environment of cloud services. With ever-increasing threats, if nothing happens, it’s a success! We are aware of what CYQUEO’s IT security does for us in the background." – H. Lorenz Dießbacher / Head of IT
