Over the years I have spoken at a number of events, including at conferences, penetration testing training days provided by BCS specialist groups, and at local tech meet ups such as Codeharbour in South East Kent, England. It would be a pleasure to discuss your requirements with you and to provide a talk that is both engaging and interactive - I have been given some excellent questions at the end.
I am available for giving guest lectures to both secondary school (aged 11+) and at universities on subjects such as cyber security and general IT. I am a firm believer that providing learners with real-world experiences is beneficial to their development, so my talks include anecdotes and real world examples.
I can also provide hands-on workshops in a mixed "lecture and do" environment. Typically these may use of a lab environment that I have built and attendees either bring their own devices or use those provided by the host organisation.
