6 Best Nmap & Nessus Online Courses

Whereas Nessus is an accountability scanner NMAP plays the role of aligning the hosts’ open ports as well as his network. Even though these two tools are used to assess network security, they feature some differences as well. Let’s find out more about these tools. 


As we’ve mentioned above Nessus is an accountability scanner and while it scans through ports the same way NMAP does, Nessus particularly focuses on the open ports and alerts users in the event the ports have probable vulnerabilities within them. Often, Nessus is installed on a server and operated as a web-oriented application. This tool utilizes plugins to establish the presence of vulnerability on a certain machine. 

Admins log on to the Nessus interface and configure scans policies and view reports. Policies are configured to figure out the specific vulnerabilities that are being scanned. One policy could be configured to specifically establish database vulnerabilities and can be driven to operate against the user’s database servers. 

Another policy could be aimed at identifying Windows vulnerabilities as it operates against a users network. In Nessus, policies configure things that shall be scanned and devise robust scan strategies. Nessus’ cost is determined by who’s using it. For instance; you can use it free of charge under the home feed option when using it for non-commercial purposes. 

If you’re using it for commercial reasons, also known as professional feeds you may want to know that you’ll get an entire year of software updates and plugin, and email oriented support. Often, professional feeds cost $1,200 annually


NMAP discovers hosts and discovers tools. Rather than using Nessus to find various vulnerabilities against known hosts, this tool utilizes various probes to establish active IP hosts. Once a network is configured, NMAP can check various hosts to identify open ports. 

Besides, it can try to assemble extra information regarding the open ports such as establishing the database version operating on any of your servers. Nmap & Nessus are becoming critical tools in the world of programming and developers need to master them at least to scale their careers. Here are various courses which can help you improve your knowledge of these tools.
