AP-251 Secure Cabin and Flight Deck Router

The AP-251 Secure Cabin and Flight Deck Router is a compact and lightweight networking solution that can simultaneously serve as a cybersecurity appliance, a cabin router, and an applications server. It offers many of the same features as the AP-250, with an additional two Ethernet ports (for a total of six) and two ARINC-429 receivers – all designed into the same form factor.

The AP-251 also supports the latest in wireless network technology, with a 5G cellular modem and two dual band 802.11ax WiFi 6 radios, designed to improve the speed and reliability of network connectivity onboard various vehicular platforms.

Cybersecurity Appliance

Featuring an advanced avionics network IDS, the AP-251 can monitor, detect and alert on anomalous avionics network data and activities for ARINC-429, MIL-STD-1553, ARINC-664 (AFDX) and more. In addition, the AP-251 also has an integrated aircraft network and log that monitors IDS, IPS, and firewalls.

Cabin Router

Capable of managing cabin networks onboard a platform, the AP-251 contains an integrated VPN and a Policy Based Routing (PBR) firewall for secure and uninterrupted Internet usage.

Application Server

The AP-251 provides support for third-party applications, with an encrypted API that can securely transfer onboard platform data to external apps.
