Ransomware is a type of malware that lets attackers find and encrypt your most important data. They then offer to provide the decryption key only if you pay a ransom, within a short time. This is the number-one IT security challenge that you face today, with resource-limited small and mid-size businesses the most likely targets.
Cybercriminals exploit a variety of threat vectors, including email, network traffic, user behavior, and application traffic to insert ransomware. Without a comprehensive security strategy that secures all these vectors, you are almost certain to become a victim.
