Cloudflare has published its annual "Year in Review" report, providing a comprehensive analysis of the behavior and evolution of global internet traffic throughout 2025.
Data obtained via Cloudflare Radar from a global network present in over 330 cities shows that overall internet traffic grew by 19% compared to the previous year. This growth was driven by large-scale technological transformations and a deepening societal dependence on digital services.
However, this progress coexists with a growing threat environment. During 2025, more than 25 record-breaking volumetric DDoS attacks were registered, establishing new historical magnitudes. Furthermore, the report identifies a worrying shift: civil society organizations and non-profits became, for the first time, the sector most targeted by cybercriminals.
Matthew Prince, CEO and co-founder of Cloudflare, pointed out that the network is being fundamentally reconfigured by artificial intelligence and more sophisticated threat actors. He emphasized the company's responsibility in helping to navigate these drastic changes to build a more resilient digital environment.
Key findings in the digital landscape: • For the fourth consecutive year, Google and Meta remain the most popular services, while ChatGPT leads the generative AI category. • European countries dominated global indicators with download speeds exceeding 200 Mbps, placing Spain first globally for overall internet quality. • The report also indicates that nearly half of all major service outages worldwide were caused by government actions. • One of the most significant milestones of the year has been the implementation of post-quantum cryptography, which currently protects 52% of all human traffic, providing an essential layer of security against future computational threats.
The report also highlights an intense "bot war," where Google's crawler emerged as the largest single source of automated traffic on the network.
