Air Gap

Air Gap is a UK-based company that develops network security hardware products designed to physically isolate network segments from malware and ransomware threats. The company's core technology creates physical disconnections at OSI layer 1, preventing data transmission across the gap when devices or network segments are not in use, thereby blocking the pathway malware and encryption processes rely on. The company's product line includes the Air Gap Network Switch and Air Gap Backup, both physical devices intended to complement existing antivirus and endpoint protection software rather than replace them. The Air Gap Network Switch received recognition as Network Security Product of the Year at the Network Computer Awards 2025, and the Air Gap Backup was a finalist in the same awards. Air Gap markets its products primarily to UK enterprises seeking protection against ransomware attacks, citing average remediation costs of approximately £700,000 for successful attacks on UK businesses. The company positions its hardware as a cost-effective additional layer of protection for high-value data, particularly for backup systems and other critical network segments where physical isolation can prevent malware propagation and data encryption by ransomware. The company continues to expand its product range and offers custom solutions for specific customer requirements beyond its standard product catalog.
