Methodology. LeakTrace research reflects aggregate observations across Canadian small-business scans. In accordance with standard threat intelligence practice, we do not disclose specific customer identities, absolute scan counts per report, or identifiable engagement details. Qualitative percentages and directional trends are based on operational visibility across the sectors we serve.
