We take security vulnerabilities seriously. If you discover a security issue, please report it responsibly.

DO NOT open a public GitHub issue for security vulnerabilities.

Instead, please report security issues via:

1. Email: security@axiom-jl.org (preferred)
2. GitLab Security Advisory: Use the confidential issue feature
3. PGP Encrypted Email: See .well-known/security.txt for our PGP key

Please include the following in your report:

• Description of the vulnerability
• Steps to reproduce
• Potential impact assessment
• Any suggested fixes (optional)

• Memory Safety: Rust and Zig backends provide memory safety guarantees
• Type Safety: Julia's type system prevents many classes of bugs
• Formal Verification: @prove macro enables mathematical correctness proofs
• Runtime Checks: @ensure macro validates invariants at runtime

• Dependency Auditing: Regular cargo audit and cargo deny checks
• SBOM Generation: Software Bill of Materials available
• Reproducible Builds: Nix flake ensures reproducibility
• Signed Releases: All releases are signed with GPG

• Code Review: All changes require review
• CI/CD Security: Automated security scanning in pipeline
• Secrets Management: No secrets in repository
• SPDX Headers: All source files have license headers

Axiom.jl provides built-in security features for ML models:

# Runtime bounds checking@ensureall(0.≤ output .≤1) "Output must be valid probabilities"# Formal verification@proveBoundedOutputs(0.0, 1.0) model
# Verification certificates
cert =generate_certificate(model, properties)

For safety-critical applications:

Axiom.set_deterministic!(true) # Reproducible results

@ensurevalid_input(x) "Input validation failed"@ensureno_nan(x) "Input contains NaN values"
