  • Antivirus software should also be used and updated regularly to help protect endpoints.
  • Backups are very importantEmployee and company data should be backed up regularly to reduce the risk of losing everything if the system crashes or is taken hostage by a hacker.
  • Confidential company files should be backed up to a remote, offline storage facility (such as offline backup).
  • Have an incident response plan with which to identify the last backup, communication protocols with the police, and isolation procedures for devices.
  • Embracing the company culture and proper cyber literacy are also key.
