As per Vivek
It’s a community driven videos website for computer networking and security related fields. Though there are many video sharing websites available online, SecurityTube.Net is strictly focussed on hosting computer networking and security videos only. We have started this site to provide a knowledge sharing platform for security professionals, so that they can reach out effectively to a wider and focused audience
The collection is very good and is useful for every learner starting for beginners to experts.
The best part is that one can also embed a video from securitytube.net into his/her blog
Good work Vivek!
