Brennon Thomas

Infosec / Automator / Builder / Creator

Hello! I'm Brennon and my passion is improving cyber and information security through automation and coding. These days, I find building more rewarding than breaking and love the creation of new tools, frameworks, and processes and excel at distilling strategic high-level problem sets into tactical and operational solutions that are sustainable and secure.

I've been in the information security field for 16 years doing everything from computer network exploitation, hunt, research/development, vulnerability analysis, and computer network operations.

Opsdisk LLC is used for my various side projects. If you're a startup, established company, or have an interesting product or idea I may be able to help or consult with, feel free to reach out via Email, Twitter, or LinkedIn
