    My keynote () in a tweet thread. I spent years focusing on the technical offense: red teaming, pen-testing, and security research. I felt that it wasn’t having enough impact, so pivoted to defensive security engineering. I learned 3 key lessons:

    I’ve hired a few people in my time. I’ve never been disappointed by hiring someone who is less technical but is a great human who cares for others. I can teach tech pretty easily. But boy have I seen people who are strong technical people with toxic attitudes destroy a team.
