Most business owners think cybersecurity is about hackers in hoodies breaking through firewalls. The reality is far simpler, and far scarier: your biggest security risk is your own people.

In this episode, Miguel sits down with Matt Mulcahy, founder of Miami Cyber, to unpack what cybersecurity actually looks like for small and mid-sized businesses in the age of AI. Matt shares how a $25 million wire transfer was approved by a real executive on a real video call, except the "executive" on the other end was an AI-generated deepfake. From there, the conversation moves into the practical: how AI is changing phishing, why passwords are on their way out, and what it actually means to adopt AI responsibly instead of just rolling it out and hoping for the best.

If you're a founder trying to figure out where AI ends and risk begins, this episode breaks down exactly what to prioritize first.

Other insights from this episode include:

  • Why "vishing" (voice phishing) is now a real threat, thanks to AI's ability to clone a voice from just 10 seconds of audio
  • The most common cybersecurity gaps Matt sees in companies under 20 employees, and why most IT providers don't prioritize that segment
  • Why policy should come before technology when rolling out AI in your company, and what that policy conversation should actually cover
  • The hidden risk of giving employees AI tools without training, and why "buying licenses" isn't the same as adoption
  • Why passkeys and authenticator codes are replacing SMS-based two-factor authentication, and what business owners should switch to now
  • The real difference between a company that's "using AI" versus one that's leveraging Model Context Protocol (MCP) to connect AI directly to their business data
  • Why Matt believes the technology itself is the least important part of a successful AI rollout, and what actually drives success or failure
