"I love the easy to understand explanations. The set-up was the difficult part, but now I'm flying through the course. Thanks!!!!!!" by Sancho


What’s so special about this course?

Well, let me tell you what's this course all about:

  • Learning to use the amazing Scapy module and all its capabilities.
  • Building network attacking and scanning tools and testing them against Windows / Linux / Cisco targets.
  • Building your own (basic) version of NMAP and scanning Windows / Linux hosts.
  • Performing various small network tests and operations using the Scapy interpreter.

Still not enough for you? Let me describe a few more features of this course:

  • More than 20 scripts for you to download and use right away, for free.
  • An amazing optimized Linux Ubuntu VM, with all the tools, modules and dependencies already installed.
  • Quizzes and a final network security project for you to build and implement in your test lab/network. Also, the solution for the project is explained and tested.
  • 1080p, Full HD videos. Improved audio quality.
  • 115+ lectures and counting. 4.5+ hours of content.
  • Concise and focused lectures. Straightforward configuration of devices. Less software and operating system complications. Less code to write and troubleshoot.

"Very clear and understandable instructions" by Lorenzo J. Ireland


Equipped with full working scripts (in .py format) and an amazing virtual machine, you will be able to work alongside me on each lecture and each application. I will provide the full code for each application, so you can save time and start coding and testing on the spot.

Warning! All the information, concepts and code in this course should be used in isolated, test environments and for learning purposes only. Otherwise, you may be accused of criminal activities, according to the law.

"Useful and well organized training. Presented in a clear manner, easy to follow. Thank you!" by Vojkan


Important prerequisites before you enroll:

  • You should already be familiar with networking concepts like: TCP/IP, UDP, OSI Layers, Packets, Frames, ICMP, ARP, DHCP, VMs (Virtual Machines).
  • You should already be familiar with Python syntax: functions, if, for, while, string and file operations etc. If you have no experience whatsoever in Python, then I encourage you to also check out my "Python Network Programming - Part 1: Build 7 Python Apps" course, which teaches Python from scratch and then dives into using it on network devices, by building some great network apps.
  • For running the Ubuntu 15.10 Virtual Machine I provide, dedicating 2 GB of RAM will be more than enough.
  • You won't have to buy anything else. I am going to use only free software throughout the course: VirtualBox, Linux, free VM etc.

Important information before you enroll:

  • In case you find the course useless for your career, don't forget you are covered by a 30 days money back guarantee, full refund, no questions asked!
  • Once enrolled, you have unlimited, lifetime access to the course!
  • You will have instant and free access to any updates I'll add to the course.
  • I will give you my full support regarding any issues or suggestions related to the course.
  • Check out the course curriculum for a quick insight.

"Excellent course so far (only 4 lessons in). Course is well organized and logical. I know Python well so using it for network purposes is very natural. C or C++ is too close to the silicon for me and forces me to spend too much time on details of the language (syntax, correct {}, ;, etc). Course style is bite-by-bite which I like. Instructor speaks English fluently, clearly. He has excellent vocabulary and sounds as if he is genuinely interested in teaching the course. I think I will enjoy this course very much. Excellent!" by Brian Crane

So, what are you waiting for? Do you want to start your network security journey?

See what my students are saying about the kind of courses I created:

"What an incredible value and learning experience!" by Sean A.

"Excellent material. Kudos to a great instructor with a vast level of creativity." by Anthony W.

"I can say this man is going on smoothly and perfectly, explaining in the most empirical/foundational way." by Kolapo A.


In early 2014 I decided to start learning a programming language that can make my daily work easier and also boost my networking career. This is when I discovered that Python, being a great language for beginners, can help me write some scripts that connect to network devices and perform various tasks I was doing manually, thus saving a lot of time. Also, working as a tester, I used Python to automate a lot of network tests, about 250, in a short period of time, again reducing my workload.

For all the above reasons and because there is a lot of Python material out there on the Internet that may seem discouraging for you as a beginner, I decided to build courses that take you from zero programming knowledge to advanced topics, all in a hands-on fashion.


In March 2015 I started working on my first course, "Python Network Programming - Part 1: Build 7 Python Apps", without really knowing what is online education all about and with no prior teaching experience, either online or offline. I just wanted to try it for some reason, despite a lot of mental obstacles, a full time job and zero experience in teaching people.

I worked a lot on this first course, with countless hours of researching, recording and editing, but there was something that kept me going further. In May 2015 my course was approved by Udemy and was an instant success, despite my low expectations. Gradually, the course became a bestseller on other e-learning platforms, as well. One example I'm very proud of is the GNS3 Academy.

In April 2016, I finished working on Part 2 of the Python Network Programming series, called "Multivendor Environment", after about three months of researching, testing, summarizing, simplifying, recording, editing and structuring the course content.

Finally, in September 2016, I released Part 3 of this amazing course series, called "Python Network Programming - Part 3: Scapy & Security Tools", which in my opinion is very interesting and exciting for anyone wanting to enter the world of network security in a 100% hands-on fashion.

I am really putting a lot of energy and effort into each of my courses and I am always trying (and succeeding) to pay special attention to the smallest details and provide a lot of value to my students.

I really think my courses will get better and better, both by learning from my mistakes and carefully listening to the feedback I get from my students.


So, check out my courses and stay tuned for more!
