The New Altitude of
Aviation Security.
Under DO-326A/ED-203A, cybersecurity is a mandatory criterion of airworthiness — not an add-on. We built the tools that make compliance achievable.
Airworthiness security is not optional. It is certifiable.

Aviation threats are invisible in public databases.
The gap between general cybersecurity intelligence and aviation-specific threat reality is not a gap — it is an abyss.
01 / Compliance
DO-326A compliance is manually broken
Certifying an aircraft system under DO-326A/ED-203A requires combing through hundreds of pages of documentation. Most organisations spend months doing this by hand — introducing human error at every step.
02 / Intelligence
Public CVE databases are blind to avionics
NVD, MITRE, and industry SIEMs were not built for ARINC 429, AFDX, or MIL-STD-1553. Vulnerabilities in avionics protocols do not appear in general-purpose threat feeds.
03 / Infrastructure
Certification data cannot touch the cloud
Aircraft certification artifacts contain some of the most sensitive IP in the industry. Feeding them into cloud-based AI tools is an unacceptable exposure of sovereign and commercial assets.
04 / Standards
Three overlapping standards, zero automation
DO-326A, DO-356A/ED-204A, and ED-202A form an interlocking framework that most teams still navigate manually — a systemic bottleneck for every certification programme.
This is what CompliAir sees.
Hover any component in the architecture diagram to see its DO-326A Security Objectives, active protocol vulnerabilities, and rule violations — in real time.
CompliAir applies this same analysis to your actual system documentation. On-premise. In seconds.
