Provability Audit

Independent Systems Assurance Assessment

Most organizations believe their systems are compliant, secure, and well-controlled.

Very few can prove it.

The Provability Audit is a focused, independent assessment designed to answer a single question:

What can you actually prove about the integrity, provenance, and auditability of your systems under adversarial or regulatory scrutiny?

This audit is not a penetration test, a policy review, or a checklist exercise. It is an architectural and evidentiary analysis of how truth, control, and accountability are enforced (or not enforced) in practice.


What the Audit Examines

Depending on scope, the Provability Audit evaluates:

  • Build and deployment provenance
    Whether software artifacts can be mechanically traced to known source, environment, and process — and whether tainted artifacts can be rejected.
  • Control enforcement vs. policy reliance
    Identification of where controls are enforced by systems versus assumed through procedure or trust.
  • Audit evidence generation
    Whether required evidence exists continuously and automatically, or must be reconstructed under pressure.
  • Change integrity
    How configuration, data, and operational changes are detected, attributed, and justified.
  • Human trust points
    Identification of undocumented, implicit, or high-risk manual intervention paths.
  • Adversarial and failure models
    How the system behaves under insider error, process drift, tool compromise, or partial system failure.
  • Analytics and AI assurance (optional)
    Traceability of data sources, inference justification, confidence decay, and contradiction handling.

The audit explicitly distinguishes provable guarantees from probabilistic or aspirational claims.


What You Receive

Deliverables are designed to be usable by executives, auditors, and technical teams.

You receive:

  • Provability Map
    A clear articulation of what your system can and cannot prove today.
  • Assurance Gaps
    Specific points where claims of compliance, security, or correctness are not mechanically enforced.
  • Risk Prioritization
    Identification of failure modes with regulatory, financial, or operational consequences.
  • Control Recommendations
    Architectural changes that convert assumptions into enforceable guarantees.
  • Audit Readiness Guidance
    Practical steps to make future audits routine, boring, and survivable.

No generic maturity scores. No marketing language. No unnecessary tooling recommendations.


What This Is Not

To avoid confusion, the Provability Audit is not:

  • A penetration test
  • A compliance checklist
  • A vendor evaluation
  • A SOC report
  • A staff augmentation exercise

It does not attempt to assign blame or score teams. It exists to surface truth.


Who This Is For

The Provability Audit is appropriate for organizations that:

  • Are subject to regulatory or contractual audit
  • Have experienced fines, audit findings, or near-misses
  • Operate critical or high-impact systems
  • Deploy complex CI/CD, analytics, or AI pipelines
  • Suspect their current controls rely too heavily on trust

If you are comfortable with uncertainty, this audit is unnecessary.


Engagement Structure

  • Fixed-scope, fixed-fee engagement
  • Typically completed in weeks, not months
  • Minimal disruption to operations
  • Independent and confidential

Follow-on architecture or implementation work is optional and not required.
