Looking back nullcon 2014

Nullcon 2014 happened at an interesting time for me. I had moved back to Bengaluru (from the US) 3 months ago and was trying to understand the Information Security scene in India. After attending a couple of null Meets in Bengaluru, I was excited about the variety of areas folks were working on. One of the volunteers in Bengaluru told me about nullcon and encouraged me to attend. While I had heard of nullcon (my colleague Ksenia had presented in 2013), I did not know much about the conference. After a little bit of research about the conference and looking at the lineup of speakers, I decided to give it a shot. The fact that it was being held at a sea-side resort in Goa, certainly made the decision easier.

null Security Community described in Numbers

When we started null – The Open Security Community, we didn’t really plan beyond the monthly gathering of infosec peeps and enthusiasts in cities like Pune and Bangalore.

We didn’t ask for registration, take any attendance (beyond a cursory head count) and things were swell.

What we didn’t really think about (atleast I didn’t) was that we would still be doing this with enthusiasm and passion 5 and 1/2 years after we started. It is quite natural to start thinking about the next level after gaining proficiency in doing security related events month after month.
