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.
DDoS protection isn’t an add-on—it’s built into Sucuri’s Website Firewall and included with all Complete Website Security Platform plans. That means you get real-time threat mitigation, global traffic filtering, and performance optimization in one solution. No need to juggle multiple vendors or pay extra for essential protection.
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.
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.
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 Updates aren’t always feasible: plugins may conflict, themes may be outdated, or the CMS may no longer be supported.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.
