We use Kaspersky in our network as well. Kaspersky Network Agent is the agent installed on client machines to report back to the security center (or the central point of command for your IT staff) The Agent itself is not responsible for the AV. Its simply the means to which the Endpoint manager(the AV on the system) can communicate with the Security Center server.
The agent also takes in the responsibility of installing applications remotely, managing endpoint encryption, and a few other Kaspersky features.
The reason you can't see the agent is because its a background service. Its just controlling and issuing the policies to the Endpoint Manager. Now if you can't see the endpoint manager it is possible for the IT staff to hide this with the "Self-defense" options. The IT staff where you work obviously does not want you tampering with the Endpoint manager and they would surely see the Audit arise in the Security Center if you did. For good reason though. Kaspersky will aide(not eliminate) in helping reduce your laptops attack surface and preventing possible compromise.
If you feel that only the agent is installed( and verified you don't see the signature "K" symbol in the task tray), it might be wise to call your IT department and ask if the system is being protected. Surely if they were using Kaspersky they could view the managed systems and see that your device is unprotected, if the agent is functioning and communicating properly.
