Ten Best Network Scanning Tools for Network Security

Network security, in today’s world, needs no introduction or explanation. We all know that the term network security refers to the securing of any computer network, aiming to prevent anyone from accessing, manipulating or misusing the network in any way. Thus, we have rules, policies and instructions that pertain to the monitoring and securing of computer networks.

Network scanning, which is integral to the process of maintaining and ensuring network security, refers to the process of detecting and identifying network vulnerabilities and loopholes so as to prevent others from accessing or monitoring a network in an unauthorized way. There are scores of network vulnerability scanning tools available in the market today, some free and some paid. These come with a variety of features.
