Draft Safety Assessments
(ARP4761A & ED-135)
in days, not months
evidion automates manual FHA and PSSA workflows while maintaining 100% engineering ownership. It catches logical errors and inconsistencies instantly across your entire project, enabling small teams to deliver signature-ready assessments in days.

Unscalable workloads
Small engineering teams are routinely tasked with the workload of entire departments. When massive SDD revisions drop with aggressive deadlines, the required math simply does not scale.
Fragile manual tracing
Design evolution requires constant, fully manual impact analysis until design freeze. A single modification affects multiple systems, draining engineering resources and frequently creating fatal, late-stage safety gaps.
Paralyzing revision loops
Safety assessments naturally require iterative review with multiple stakeholders. However, undocumented assumptions and manual data errors force teams into endless revision loops, blocking actual engineering.
One unified safety workflow
Catch what manual reviews miss
Upload your SDD, FHA or PSSA. evidion checks and identifies logical errors, discrepancies, hidden assumptions, DAL misclassifications, severity mismatches with full traceability and rationale. Peer review your report with one click.

Find inconsistencies across your entire document set
Keep your full project library (SDD, FHA, PSSA, ICD and more) consistent and aligned. evidion checks every document in parallel, surfacing contradictions, traceability gaps, and logical conflicts that span multiple sources.

Trace design changes across all documents
Submit a design change, and evidion instantly traces its impact across your entire project. It maps the change directly to affected failure conditions, safety requirements, and DAL allocations, ensuring every downstream impact is resolved before sign-off.

First-draft FHA in days, not months
The engineer uploads the input documents (e.g., SDD). evidion generates the FHA strictly following the step-by-step ARP4761A and ED-135 process, providing full traceability and rationale. 100% engineering ownership is guaranteed through explicit review and sign-off at each step before advancing to the next assessment step.

Ask the project documents anything
The engineer queries the entire document library in plain language. Every answer cites the exact source, document, section, and page number. No hallucinated safety data. No guessing. The project documents, finally searchable.

The math is simple.
From engineer reading SDD first time to complete first draft
Based on average safety engineer hourly rates (including overhead) across an FHA cycle.
Critical inconsistencies are flagged immediately upon document upload, not during final design review.
Benchmarks based on case studies and close-alpha. Individual efficiency gains depend on input maturity and system complexity.
Enterprise-grade security by default.
Your IP doesn't leave Europe. Your documents don't train our models. Your engineer still signs off.
Built for regulated industries
evidion infrastructure is built on the same foundations trusted by leading aerospace and defense companies (Airbus, Boeing). GCP and Azure hold ISO 27001, SOC2 Type II, and C5 certifications – providing enterprise-grade compliance inherited directly by your deployment.
EU-First Infrastructure
Account data and documents are stored on EU-region infrastructure (Azure West Europe, Supabase/AWS EU). Deployment options include shared VPC, private cloud, and air-gapped enterprise deployments.
Zero-Training Policy
Data is encrypted and isolated in transit and at rest. Your engineering documents are never used to train foundational AI models. Data is deleted after processing.
