Link11 Releases European Cyber Report 2026: DDoS Attacks Become a Constant Threat

Why It Matters

Continuous, high‑volume DDoS activity is eroding service availability, revenue, and regulatory compliance for European enterprises, making robust, always‑on protection a strategic imperative.

Key Takeaways

• DDoS attacks rose 75% in 2025.
• Longest attack lasted over eight days.
• Three attacks exceeded 1 Tbit/s in 2025.
• 70% of initial victims face follow‑up attacks.
• Hybrid volume‑endurance tactics target Layer 7.

Pulse Analysis

The 2026 Link11 report paints a stark picture of Europe’s cyber‑threat landscape. Attack frequency jumped 75% in 2025, and continuous assaults now occupy 88% of the year, equivalent to 322 days of relentless pressure. A single 12,388‑minute episode—over eight days—demonstrates that DDoS is no longer a fleeting nuisance but a structural burden. The cumulative 509 TB of malicious traffic rivals the daily data flow of a mid‑size city, underscoring the scale at which businesses must defend their digital front doors.

Beyond sheer volume, attackers are refining tactics. Modern campaigns fuse terabit‑scale bursts with endurance attacks that linger at lower intensities, often slipping beneath traditional detection thresholds. By shifting focus to Layer 7, they mimic legitimate user behavior, exploiting APIs and web applications to degrade performance without triggering classic alarms. This hybrid approach forces defenders to adopt behavior‑based analytics and AI‑enhanced bot detection, as static rule sets can no longer keep pace with adaptive threat vectors.

For enterprises, the implications are clear: DDoS resilience must be baked into business continuity plans, not bolted on after an incident. Always‑on network protection combined with Web Application and API Protection (WAAP) creates a layered defense that addresses both volumetric floods and sophisticated application‑level assaults. Automated, AI‑driven mitigation reduces response times, protects SLA commitments, and safeguards regulatory compliance. Companies that integrate these capabilities can preserve availability as a competitive advantage, turning cyber resilience from a cost center into a strategic asset.
