What Is DDoS Protection?

DDoS protection is a security solution that helps websites stay online when they’re targeted by traffic overloads. These attacks, known as Distributed Denial of Service (DDoS), flood your site with fake requests to slow it down or take it offline. For agencies managing multiple client sites, developers building performance-critical applications, and small businesses relying on uptime, DDoS protection is essential. Sucuri’s platform blocks these attacks using intelligent filtering, machine learning, and a global network designed to keep your site fast, secure, and available.

Understanding Layer 3, 4, and 7 Attacks

Understanding Layer 3, 4, and 7 Attacks

DDoS attacks come in several forms, each targeting a different layer of your website’s infrastructure. Layer 3 attacks, aim to overwhelm the network itself with massive volumes of traffic. Layer 4 attacks, exploit weaknesses in the transport layer to exhaust server resources. Layer 7 attacks are the most complex, mimicking real user behavior to overload your web applications.

Why Websites Are Vulnerable

Why Websites Are Vulnerable

Websites are vulnerable to DDoS attacks because they are publicly accessible and often lack the infrastructure to handle sudden traffic spikes. Small businesses, eCommerce platforms, and even enterprise sites can be targeted for extortion, disruption, or competitive sabotage. Without proper protection, a DDoS attack can lead to downtime, lost revenue, and damage to brand reputation.

How Sucuri Mitigates DDoS Attacks

Whether you’re an agency managing dozens of client sites, a developer maintaining custom builds, or a small business owner running a legacy CMS, keeping your website secure without breaking functionality can be a challenge. Updates aren’t always feasible: plugins may conflict, themes may be outdated, or the CMS may no longer be supported. That’s where virtual patching comes in.
