Contact Support - Helpdesk > How Secure is TeamViewer?

The following is an excerpt from the TeamViewer website as of the 8th of Febuary 2013:

Security-related inspection FIDUCIA IT AG

TeamViewer underwent a security-related inspection by the German FIDUCIA IT AG (an operator of data processing centers for around 800 German banks) and has been approved for use at bank workstations.

Security-related inspection GAD eG

The German GAD eG (operator of data processing centers for around 450 German banks) verified security-related aspects for TeamViewer. The use of TeamViewer at bank workstations (WinXP) has been approved.

Encryption

TeamViewer includes full encryption, based on RSA private-/public key exchange and AES (256 Bit) session encoding. This technology is based on the same standards as https/SSL and is considered completely safe by today's standards.

The key exchange also guarantees a full client-to-client data protection. This means that even our routing servers will not be able to read the data stream.

Access Protection

In addition to the PartnerID TeamViewer generates a session password that changes with every software start to provide additional security against unauthorized access to a remote system.

Security relevant functions like file transfer require additional, manual confirmation of the remote partner.

Also it is not possible to invisibly control a computer. For data protection reasons the person sitting on the remote computer has to be able to detect when someone is accessing the machine.
