Why it matters
- Theoretical severity causes wasted remediation effort.
- Exploitability depends on context: exposure, auth, data, versions, compensating controls and relationships.
- Teams need proof before prioritising scarce engineering capacity.
Exploitability Validation
Determine whether a weakness is actually reachable, exploitable or useful in a chain.
Evidence traceApproved scopeTarget-aware testing
Capability architecture
Prove whether the weakness works here.
Controlled validation establishes target-specific prerequisites, outcome and control behaviour before priority changes.
ThreatCanary approach
- Turn observations into hypotheses with clear validation criteria.
- Run deterministic checks and controlled tests where authorised.
- Confirm, reject or downgrade hypotheses based on evidence.
What it validates or reveals
- Confirmed exploitability.
- Rejected false positives or theoretical issues.
- Evidence explaining why remediation should be prioritised.
Evidence produced
- Reproduction steps and required preconditions.
- Request, response or state-change proof.
- Non-exploitability evidence when a prerequisite or control blocks the path.
