The Netviewer client applications consist of two programs. One is started on the computer of the session initiator and the second on the computers of the meeting participants. These programs contact the Netviewer server. In the case of Admin, the second program is installed on the computer to be administered and is in constant contact with the Netviewer servers. The Netviewer server authenticate the client programs and connect them using a random and unique nine-digit session number with each other or, in the case of Admin, by means of a minimum of eight -digit key set. Once the connection is established and the client communicate with each other, can the meeting, to look together at a chosen screen and edit documents, text messages and exchange files depending on the product variant, remotely control other computers and manage file systems, etc.

• The user can check the authenticity of the Netviewer software before the session establishment. The software is signed with a certificate from the independent certification body VeriSign certificate.

• When starting the program, the presenter presenter must authenticate with his email address and his self-chosen password. After successful authentication, a unique nine-digit session number is generated by the Netviewer server and delivered to the moderator program. This number is transmitted by phone or e -mail to the participants.

• It can be a session password can be used. Ensuring only inaugurated participants in the session.

• The moderator can remove individual participants from the session.

• The moderator can lock the session for new participants.

Privacy

• None of meeting participants, it is possible to gain the right to control the computer of a session partner without its consent.

• The session partner must explicitly allow any change in the status of your computer ( change of perspective, remote control, file transfer). Only after the release is another session partner able to remotely control the computer or perform other actions.

• Applications or files that should not be transferred to the session partners can be selected explicitly. As example it is possible to hide the desktop or the tray. Non-shared applications and screen elements can not be operated via the remote control.

• The session partner, who shows his screen can interrupt the transfer screen and transfer a still image to edit during the meeting confidential data or applications ( Pause function of the Monitor tray ).

Software as a Service, or your own server operating

Basically Netviewer provides two ways to operate the software: About the Model Software as a Service (SaaS ) or running the software on its own Netviewer server

SaaS

The Netviewer client programs are distributed within an organization. To start a Netviewer session, contact the client programs, the web collaboration server Netviewer AG on the Internet that take over all other functions. The advantage of SaaS compared to a dedicated server is clear, the minimum initial effort and that the initial investment can be kept low. A disadvantage of SaaS dependence on a foreign infrastructure is to be evaluated.

Private Server

An in-house Netviewer server is placed in its own corporate network. The contact Netviewer clients no longer the web collaboration server Netviewer AG on the Internet, but the company's own Netviewer server in your own corporate network.

An in-house server is ideal for companies with high security requirements, specific integration requirements, high Netviewer license numbers and the desire for an in-house server solution for internal communications or for businesses that are committed to the introduction of this model due to safety of their organization.

A separate server saves the company Internet bandwidth and bring the issue of security in their own area of ​​responsibility, because all of the traffic originating within the network, the IT infrastructure of the company does not leave.

In case of redundant applied Netviewer Server Infrastructure are other advantages: reliability, load balancing and the ability to Netviewer clients to configure their own requirements accordingly and perform integrations.
