6. Student Testimonials from our existing Certifications

SecurityTube Certifications are currently taken by students from over 73+ countries around the world! Here is what our students have to say about us:

I am working for a WISP and have more than 5 years experience in wireless networks. I was looking for a wireless security course which would be comprehensive and structured, and which explains the basics to the absolute bleeding edge advanced. The pedantic approach to learning using practical and challenging labs is what made me take the SecurityTube Wi-Fi Security Expert course and certification. Vivek’s videos provide a perfect way to learn and the student forum allowed me to clear my doubts and get hints and tips to solve my existing problems, and to explore new things which I never thought before.

– Andrea Consadori
Lais S.R.L

SecurityTube and Vivek Ramachandran are making a significant contribution and impact in the field of Information Security Education. My experience completing SecurityTube Wireless Security Expert has been fun and highly satisfying. The SWSE Course content is of high-quality, hands-on & crystal-clear to understand. Vivek has the unique gift of transferring his knowledge seemingly casually yet very effectively. The technique of breaking topics into delicious small-chunks make them easy to absorb irrespective of the complexity of the subject.

After passing the SWSE, I am having fun doing SecurityTube Python Scripting Expert course!

– Sarveshwar Rao
Sr. Security Product Manager

The coherent teaching style and technically challenging lab exercises in the SecurityTube Metasploit Framework Expert certification help towards a gradual and comprehensive learning curve for the student.

– Jamie Rougvie

I found the SecurityTube Metasploit Framework Expert course videos very elaborate, easy to understand and very practical. This is a high level certification with a really great material and quality. I found what I was searching in SecurityTube, and is very sure I’ll going taking the next certifications offered. I’m not a profesional of security, I’m Engineer in Computer Science, most of all a programmer but always I’ve been enthusiastic of security. With the SMFE I learning a lot and has made me better in the world of security. Congratulations to Vivek Ramachandran excellent teacher and the whole team of SecurityTube. I’ll be available to help and contribute in all I can and be part of this team.

– Sigfredo Alvarado
Engineer in Computer Science

Generally, all you can find is “programmers speaking to programmers” but now with the SecurityTube Python Scripting Expert every one can learn Python. Programming is a state of mind and this is not my case, with the SPSE I finally found a clear course that not teach me how to create a recipes book or a little game but how to interact with your environment inside your network or the internet only with Python. I must admit that SPSE (for me) is more complicated that SWSE and SMFE community but you will learn so much that you cannot miss this opportunity; low price for rich and useful content.
