About Derek

"The way to get started is to quit talking and start doing." - Walt Disney

Over the last 20 years, it has been my privilege & passion to start, fund & run companies, sharing my experience with others along the way. It has always been very personally satisfying to help business owners, executives, startup founders & students to improve their entrepreneurial plans, businesses, outlooks or strategies.

My career has had a frequent focus on cyber security. Going back to my time as a U.S. Navy Officer where I was introduced to communications security, management and intelligence; to co-inventing Intellishield™, a pioneer IT security product which was later acquired by Cisco Systems; co-founding NexDefense, a software company focused on the specific security needs of industrial control systems (ICS) asset owners.

I've enjoyed professionally speaking for many years: keynotes, workshops and guest lectures on a variety of topics. As a speaker, I often draw from my decades of experience as an entrepreneur, business owner and my work in the cyber security industry to share interesting yet relevant stories with my audiences. It is my goal to make a meaningful impact with every interaction.
