TL;DR DDoS Protection
DDoS stands for Distributed Denial of Service. It is a type of cyberattack where a large number of compromised computers or devices, often forming what is called a botnet, flood a target server or network with traffic so overwhelming that it cannot respond to legitimate requests and effectively goes offline. Unlike a regular denial of service attack which comes from a single source, a DDoS attack comes from thousands or millions of different IP addresses simultaneously, making it much harder to block. CloudSonic mitigates DDoS attacks through Cloudflare Enterprise, which absorbs attack traffic at the network edge before it ever reaches your origin server. This protection is active on every CloudSonic plan from day one and works alongside our WAF and bot protection for layered defence.
How DDoS Protection Works
DDoS protection works by sitting between the internet and your origin server and absorbing or filtering attack traffic before it reaches your infrastructure. When an attack begins, the protection system detects the sudden abnormal surge in traffic volume and analyses it to distinguish attack traffic from legitimate visitors. Attack traffic is identified by patterns such as requests coming from known malicious IP addresses, traffic that does not match normal browser behaviour, requests targeting a single endpoint at impossible speeds, or traffic arriving in volumes that exceed any realistic user base. Once identified, the attack traffic is dropped at the network edge while legitimate requests continue to be served normally.
The effectiveness of DDoS protection depends almost entirely on network capacity. An attacker generating 500 gigabits per second of traffic can overwhelm any protection system that does not have more than 500 gigabits of capacity to absorb it. This is why enterprise-grade DDoS protection like that provided through Cloudflare Enterprise is so significant. Cloudflare's network capacity far exceeds the largest recorded DDoS attacks in history, meaning it can absorb attack traffic without any degradation to your site's availability. The protection is always on and requires no manual intervention during an attack.
Why DDoS Protection Matters for Your Website
A successful DDoS attack takes your website completely offline for the duration of the attack. Attacks can last minutes, hours, or days depending on the attacker's resources and motivation. During that time every visitor who tries to reach your site gets an error, every potential customer is lost, and every minute of downtime damages your reputation and your search rankings. The threat is not hypothetical or limited to large enterprises. DDoS attacks are routinely used against small businesses, WordPress sites, and independent developers by competitors, disgruntled users, or opportunistic attackers using cheap for-hire attack services. The only effective defence is network-level protection with sufficient capacity to absorb the attack volume. Server-level mitigations like blocking IP addresses are insufficient because the attack is designed to overwhelm the server before any blocking can take effect. Network-level protection through Cloudflare Enterprise intercepts the attack before it reaches your server entirely.
