A multifunctional cybersecurity appliance is physically installable between a processing environment (e.g., an aircraft or other mobile platform) and external networks with which the processing environment is in communication. The modular appliance combines multiple cybersecurity and cryptographic modules within a hardened housing or chassis. For example, a perimeter firewall provides a demilitarized zone (DMZ) network providing a first line of defense by admitting or denying inbound traffic from suspicious addresses or ports. Cryptographic modules encrypt and decrypt secure data traffic. Next-generation firewall (NGFW) components provide further packet inspection of decrypted inbound traffic to guard against internal attacks. A security information and event management (SIEM) module monitors event logs from other components of the appliance and generates an alert when anomalous activity is detected.
