Encrypted cell phone for defending against hackers and data theft. It guarantees a high level of protection for calls, messages, web browsing etc.

Safe operating system

The Zimmermann smartphone provides a high level of protection when you are going to communicate with other phones or connect to sites, social networks, messaging apps, FTP servers, and so on. The phone is equipped with an Android-based operating system, expressly designed to protect you from any attacks of malware, trojans, viruses, network sniffing, leackage etc. used in mobile data theft. The Zimmermann's OS is not recognized by viruses and trojans at all, so that it does not become accessible to infections or intrusions.

High level mobile security

All secure calls made with this smartphone are over IP (VoIP) and encrypted. Thus they are absolutely immune from attacks such as "Man in The Middle" carried by interception equipment (IMSI catcher, GSM interceptor etc.) that force the listening of calls via GSM and attack what is the standard coding of the network network. The connection between the smartphone and the cell phone bridge is constantly monitored by a control server that guarantees its authenticity. Data exchanged to or from the mobile phone take place safely, without the risk of being identified or, still worse, compromised by hacking. Anyway the system is equipped with two types of dialer: one for encrypted calls and the other for normal GSM line using a SIM card inserted in the phone, while for protected calls (VoIP) no SIM is required, just a data connection, for example WiFi with the help of a portable modem.

Secure calls from/to non-encrypted phones

Not only the communications affecting two or more Zimmermann smartphones, but also those occurring between other normal mobile phones or landline phones* may benefit of the same protection level by their side. The call to any other unprotected phone number is in fact protected by the passing through the control data center which ensures that the request is made to carry out the call on the GSM line to the recipient. Instead when you receive a call from an unprotected phone, this latter does not directly call the GSM SIM card inserted in the Zimmerman smartphone, but actually it composes a virtual phone number registered on the server in charge to pass the call from the control center to the destination Zimmerman smartphone. The call thus made will be equally over IP, then protected and encrypted.

Furthermore this system allows to completely mask the real position of the Zimmermann mobile phone, so that it will not be possible to trace the virtual phone number as it will never be registered on the network.

OS virtualization and protected spaces

Among the most innovative ZImmermann Mobile's features, we can find the ability to virtualize the whole operating system as well as the creation of multiple accounts and virtual spaces, that are completely customizable and independent of each other (up to 4 virtual spaces).
