It always gives an pleasure and amazing feeling when someone ask me “Hey, I wanna learn more security stuff” and I say ” why don’t you go there..” And response is always “do you mean Dwarka or vikas and govil..?? I always add by saying proudly that whatever I am or where ever I’ll go is all because of them. No alternatives no confusions just go and grow.


Firewall Firm is the place where the guidance and learning given is completely extempore and in depth. A topic is covered till even a single person is able to answer almost everything about it with confidence. So I like the way a topic is chased and learned to everyone with exposure to real time industry scenarios.

Firewall Firm is certainly a tremendous approach to master the information security aspects and technologies. It helped upgrading my signature from technical support to It security Specialist and ensures more upgrades in near future.


I worked with an MNC for last 3 years in a track which has no growth and career options. So started my Hunt and of course Search engine is the first that we use. Some of my friends recommended to go with IT/Network security as a first Go and suggested me to Join Firewall Firm. The very first day in Firewall Firm gave me a lot of learning, confidence, opportunities, reasons and most important Learning and growth is a priority.
It’s almost 1 year I have completed with troika and still thankful that I did not opt to use Search Engine optimization for a hunt of institutes.
