Ransomware Protection with Air Gap 

Learn more about how to prevent a ransomware attack and how air gapping adds a layer of security to help safeguard your data and mitigate ransomware risk.

A Ransomware attack is far more likely to occur today than ever before, and any organization could fall victim. It is predicted that by 2031 ransomware attacks against businesses are likely to occur every 2 seconds1. Ransomware demands have grown from an average of $6,000 to $570,0002, and growing. If companies fall victim to an attack not only may it affect revenue, but it may also hurt your brand.   

Air-gapping as a deterrent to ransomware attacks 

Air gapping adds a layer of security to help safeguard your data and mitigate ransomware risk. It is designed to isolate and segment secondary or tertiary backup copies and make them inaccessible from the public portions of the environment. If your organization is infiltrated by ransomware or a malicious attacker, the cyber threat will have a limited attack surface. The public portions of the environment may get infected, but the isolated data will not because it cannot be accessed. The backups are safe, secure, and available for restoration. By storing a backup copy on a storage infrastructure that is physically inaccessible from an external connection, you restrict access and drastically limit the potential for infection. 

Compare air gap to defending a medieval castle. The castle is surrounded by water, and the only access to the castle is if the drawbridge is let down periodically to bridge the gap. To learn more about air gap refer to this video:
