Ransomware is far from dead and is still a significant threat to all organizations with sensitive data they cannot live without. The City of Atlanta is suffering a compromise as we speak. Please make sure you have addressed this threat. Have a tested and viable backup of your key data in place. Make sure you can recover quickly after an incident. Run some form of DNS-based content filtering. Consider non-signature based advanced malware protection. Most importantly, train your employees and associates!
