  1. Secure every device in your operation: Run antivirus, implement a strong firewall, and update every piece of software with the latest patches.
  2. Educate your staff: Train employees not to provide personal info in email, text messages, phone calls, or IM. Scan incoming communications for known threats. 
  3. Make sure IT knows when employees are traveling: Make traveling employees use VPN when accessing any resources while out on the road.
  4. Disable unnecessary Windows processes: Volume Shadow Copy Service admin doesn't always need to be enabled and can be hijacked by ransomware. Also consider disabling PowerShell, Windows Script Host, file sharing, and AutoPlay unless you have a specific need for those services.
  5. Make good and frequent backups: Be sure to store backups separately from other systems and know how to restore them. The easiest way to recover from a ransomware attack is to be able to restore your own data yourself.

Granted, there's no 100% way to prevent ransomware, but every step you take that gets you closer to being unaffected is a good step to take.
