Gray-Zone Aggression Threatens European Businesses With Silent Sabotage

Gray-zone aggression—ambiguous, deniable tactics between peace and war—now poses a serious threat to businesses across Europe. Between October 2025 and March 2026, at least 47 such incidents were recorded, targeting energy, technology, and logistics sectors. Hostile states are exploiting economic ties to create disruption with little fear of retaliation.

Think tanks like the Atlantic Council and the EU Commission documented a surge in gray-zone tactics over the past six months. Russian cyberattacks hit gas pipelines in Germany and Poland, while Chinese IP theft affected tech firms in France and the Netherlands. Ports in the Baltic states also faced sabotage, disrupting trade routes.

These tactics have spread beyond aviation and shipping, now threatening entire industries. Companies must treat gray-zone aggression as a top-level risk, requiring constant monitoring and updated response plans. Crisis teams need training to act decisively when the source of disruption is unclear.

Experts urge businesses to rethink supply chains through a geopolitical lens. Diversification and 'friendshoring'—relocating operations to allied countries—can reduce exposure. Insurance policies should also be reviewed to cover ambiguous threats, with clearer triggers and limits.

Strategic foresight and operational readiness must become core parts of risk management. Specialised solutions are needed to address uncertainty, as traditional defences often fail against deniable attacks.

The rise in gray-zone aggression means businesses can no longer assume immunity. Strengthening defences, adapting strategies, and collaborating with partners will be key to maintaining stability. Without action, companies risk prolonged disruptions and financial losses in an increasingly volatile environment.
