Cyber-Attacks on Small to Medium-sized Businesses (SMBs): The Numbers

  • 43% of cyber-attacks target SMBs.
  • Around 42 million U.S. people have been affected.

These stats show that SMBs are major targets. The damage isn’t just in dollars—it hits our communities. Protecting against this means acting fast and smart.
