Automation of cybersecurity tools using Python

We started this chapter by showing all the benefits of automation. Now, it's time to see how we can leverage Python to achieve automation.

Python is a super-intuitive language that is widely used for scripting and automation, and we can also leverage it to automate some cybersecurity-related tasks.

In fact, you can automate almost everything you want with Python, including automating well-known cybersecurity tools such as Nessus, Nexpose, Shodan, Nmap, Metasploit, Sqlmap, and more.

However, in this section, we are going to discover other ways to automate cybersecurity tasks with Python.
