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.

The Problem Space

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.

Products

Two products. One mission.

Built specifically for aviation — not adapted from general-purpose cybersecurity tooling.

Product 01 — DO-326A Automation

CompliAir

An LLM-powered engine that automates DO-326A/ED-203A risk analysis. Identify Security Objectives, map threat conditions, generate compliance evidence — in seconds, not months.

  • Automated Security Objective identification from documentation
  • DO-356A / ED-204A method cross-referencing
  • Threat condition mapping with CVSS-A scoring
  • Audit-ready EASA & FAA DER format output
  • Fully on-premise — zero data egress

Product 02 — Aviation CVE Intelligence

VulnAirabilityDb

The first on-premise vulnerability database built exclusively for avionics and aviation communication protocols. Coverage that does not exist in any public threat feed.

  • Aviation-exclusive CVE entries not in NVD or MITRE
  • ARINC 429, ARINC 664 (AFDX), MIL-STD-1553 coverage
  • Air-gapped deployment compatible
  • Structured for DO-326A threat condition mapping
  • Signed offline intelligence update packages
