Traffic, protocols, and cyber threats: an overview of the Cloudflare 2025 report

The Internet is a living organism that changes every second. Cloudflare, processing a significant portion of global traffic, has presented its annual Cloudflare Radar report. The Year in Review 2025 document details changes in routing, protocol usage, and the cyber threat landscape.

For IT directors and network engineers, this data is not just statistics, but a roadmap for planning security architecture for the coming year. As an official distributor, Softprom helps companies adapt to these changes.

Traffic distribution: the battle of protocols

One of the key themes of the report was the distribution of traffic between the aging IPv4 and modern IPv6. Despite the address shortage, IPv4 continues to hold its ground, but the momentum of the transition to the new standard is accelerating.

IPv4 traffic

• Dominance: Still constitutes the backbone of corporate traffic in many regions.
• Challenges: Exhaustion of address space and high maintenance costs.
• Security: Requires additional protection layers (NAT) and complex routing.

IPv6 traffic

• Growth: A significant spike is observed in mobile networks and the IoT segment.
• Advantages: Simplified routing and built-in security mechanisms.
• Outlook: Becoming the default standard for new deployments in 2025.

Understanding the structure of global traffic allows businesses to optimize application performance and protect against DDoS attacks, the power of which grows proportionally to channel bandwidth.

Why the Cloudflare ecosystem matters

Cloudflare Radar report data is collected from Cloudflare's global network, spanning hundreds of cities worldwide. This allows not only observing trends but also proactively blocking threats.

The Softprom team recommends paying attention to the vendor's solutions for protecting web resources and building Zero Trust architecture. Using up-to-date traffic data helps reduce latency and ensure 24/7 service availability.
