Basic information about Agents

Security

All information sent by the Agent is secured with TLS 1.2. The database is also password protected. To ensure that only one nVision instance can communicate with the Agent, set the Agent password in nVision.

Agent-generated network traffic

All data are compressed before sending and uncompressed after reaching nVision. Agents send small packages every few hours (this parameter can be set in nVision). Daily traffic generated by a single Agent is approx. 100 kB. The first package sent after Agent installation can be bigger (up to approx. 500 kB). The Agent is updated automatically when a new nVision installation is detected. This operation can increase the network traffic (it is necessary to send the Agent’s installation file). To prevent the network from being significantly burdened, the number of connections between Agents and nVision can be limited to a single connection (Agents will be updated one after the other).

Resources

An Agent stores approx. 30 - 50 MB of data. CPU usage should be very low (0 - 5%), up to 15% for short periods. One module, which can cause a significant CPU load is the monitoring of data sent by the users. It is caused by a Windows mechanism, which can appear on older systems, sending large amounts of data (e.g. database servers). Disabling network traffic monitoring in the profile of an Agent installed on such a computer is recommended.

Features

Files executable by Agents must be added to the exception list of the anti-virus software and DEP list in Windows. The nVision Agent has the function of e-mail monitoring and website blocking. These functions use TCP/IP stack integration and are disabled by default. This results from the fact that anti-virus software does not allow for correct integration and can lead to connection loss.
