Threat landscape 2026

The most common RF vectors
in enterprise scenarios.

Real patterns gathered by our team across 300+ classified sweeps. Detection probability and criticality calculated on data from 12 European ministries.

While IT threats are well mapped, RF vectors remain underestimated: most security audits don't include them. Our 2026 Threat Report documents the 7 main patterns observed over the last 18 months, with real operational metrics.
