Visibility is the key for security
Due to the gradual growth and complexity of network structures, it has become very important to detect and prevent unauthorized access attempts in the first place. Network Access Control (NAC) can be integrated with many different networks and security elements in the corporate network by seeing the details of all devices in the network and can prevent all unauthorized access and unwanted devices on the network.
The main danger is the dangers that come from within your network. If you do not know what is happening in your network, you will not be able to take action against threats. With NAC technology, it becomes possible to take automatic measures against threats that may occur by seeing the details of every device in a network.
