Cloudflare Identifies Key Internet Trends for 2025: Growing Cyberwarfare, Bot Wars, and Quantum Security
Cloudflare Inc News
The top connectivity cloud provider, Cloudflare, Inc., released its sixth annual Year in Review today, offering one of the most thorough analyses of traffic patterns, security insights, and global Internet trends seen in 2025. The report, which is based on data from Cloudflare’s vast global network, which is present in more than 330 cities across 120 countries, highlights a crucial year online characterized by quickening technical progress and escalating threats.
The Internet is still crucial in both personal and professional contexts, and society’s reliance on it is fueled by substantial advancements in technology. Global Internet traffic surged by 19% year over year. According to Cloudflare CEO Matthew Prince, the Internet is being “fundamentally rewired” by forces ranging from artificial intelligence to more advanced and inventive threat actors.

The Rise of AI and the Escalation of Bot Wars
Google’s crawling bot dominated the scene as the AI bot battles heated up significantly during the year. Googlebot, which crawls for both search indexing and AI training, was the largest source of automated Internet traffic, outpacing all other top AI bots. Moreover, over a quarter (more than 28%) of Verified Bot traffic in 2025 came from Googlebot. GoogleBot generated 4.5% of traffic while examining HTML requests in particular, which is marginally higher than the 4.2% that all other AI bots combined accounted for.
In the quickly developing field of Generative AI, ChatGPT/OpenAI took the lead. The study did note some noteworthy changes elsewhere, though, with newcomers like Google Gemini, Grok/xAI, and DeepSeek joining the top 10 list and Perplexity, Claude/Anthropic, and GitHub Copilot rising in the ranks.
When the aim of AI crawling was examined, model training accounted for the vast bulk of traffic. On the other hand, user action crawling, in which bots explore websites in response to queries from users to chatbots, had the lowest volume but the fastest increase, growing by more than 15 times by 2025. AI crawlers became the most commonly restricted user agents as a result of content owners responding to this spike by regularly implementing entirely disallowed directives in robots.txt files. Meanwhile, Meta’s llama-3-8b-instruct model was the most popular on Cloudflare’s Workers AI development platform, with text generation being the most common task type.

Security Milestones Amidst Dramatic Cyber Escalation
More than 25 record-breaking Distributed Denial of Service (DDoS) attacks resulted from the sharp rise in cyberwarfare brought on by the growth in worldwide traffic. This increase in volumetric attacks changed the definition of “scale” in online threats. With 4.4% of the global mitigated traffic, organizations in the “People and Society” sector, which includes civic associations, non-profits, and religious institutions, became the most targeted vertical. This was the first time that this industry had been the most attacked, most likely because of the sensitive nature of their user data and its possible financial value.
The quick development of post-quantum encryption, which currently protects 52% of all human traffic, was a significant security milestone. In order to safeguard consumers from any dangers posed by sophisticated quantum computing, this approach is essential. Over the course of the year, the percentage of post-quantum encrypted traffic worldwide doubled, rising from 29% to 52%. Apple’s mid-September operating system changes, which allowed TLS-protected connections to automatically advertise compatibility for quantum-secure key exchange in TLS 1.3, significantly accelerated its adoption.

Global Connectivity and Quality Leaders
Almost half of the 174 large Internet outages that were reported worldwide in 2025 were caused by governments, who were shown to be the main cause of these disruptions. These measures, particularly in Iraq, Syria, and Sudan, frequently involved regional and national shutdowns meant to deter academic exam cheating. On the other hand, cable-cut outages decreased by almost half.
European nations led the world in connectivity quality, with the highest average download speeds all above 200 Mbps. With average download speeds of over 300 Mbps and upload rates of up to 206 Mbps, Spain took first place globally for overall Internet quality. The UNICO-Broadband project, which aims to construct infrastructure capable of symmetric speeds of at least 300 Mbps, may be responsible for this impressive performance.
Over the course of the year, Starlink’s satellite Internet service increased the volume of requests it received worldwide, including traffic coming from more than 20 new nations and regions. Furthermore, the proportion of requests arriving from mobile devices increased slightly to 43% worldwide, with over half of all request traffic coming from mobile devices in 117 countries and regions. Go-based clients accounted for 20% of automated API calls, a substantial increase from 12% in 2024, followed by Python at 17% when looking at the technology stack enabling contemporary online apps.
