I speak at a lot of local meetups and from one of those got invited to speak at a pretty big conference (M3AAWG). It was really intimidating since the speakers consisted almost entirely of Facebook, Google, Comcast, Microsoft, Rackspace...and somehow me. I enjoyed it but was really nervous and had some serious imposter syndrome going on. I generally like giving talks but for me, it was a very different experience knowing that you were speaking for people who were paying to be there. The speaking invite allowed me to attend the conference for free though and I learned a lot. My talk was basically a practitioner's experience of using/implementing a lot of different anti-phishing/anti-fraud techniques that people were deeply specialized in throughout other parts of the conference. I had what I hope, for others sake, was a very unique experience of combating a lot of fraud and seeing things come from all angles where a lot of larger targets will tend to deal with different parts of attacks in entirely different departments. I couldn't go deep on anything, but mainly got to share my experience.
