“Sean has distinguished himself as a leader within the Free Software community. He is capable of communicating about the Free Software movement and information technology because he is immersed in it. I have gained a deep appreciation for Sean’s knowledge in his roles as a developer, activist, and educator, as well as his ability to understand and think critically at many different levels and to communicate about difficult issues to people with diverse backgrounds.”
Digital Self-Defense Training
I show people how to be safe and aware while traversing the digital landscape. Learners must approach privacy and cybersecurity step-by-step, integrating strategies rather than relying on catch-all solutions.
Cyber Attack Demos
I want people to see cyber attacks first-hand so they can guard against them. My demonstrations contain safe, simplified examples of real-world attacks that are designed for audience interaction.
