DDoS Protection & Web Application Firewall (WAF)
A DDoS attack does not have to compromise your servers to disrupt your business. By overwhelming network resources or generating large volumes of malicious application requests, attackers can make websites and online services slow or unavailable, affecting revenue, operations, and customer experience.
Cloud4U DDoS Protection helps keep your services accessible by identifying and filtering malicious traffic before it can disrupt your infrastructure. Application-layer protection adds another layer of defense against threats targeting your websites and applications.
The solution works with infrastructure hosted on the Cloud4U platform, allowing you to add protection without migrating your applications, deploying dedicated security hardware, or making complex infrastructure changes.

How Our DDoS Protection Works
Cloud4U uses a multi-layered defense strategy to protect your services at both the network and application levels. This helps address attacks that target your infrastructure as well as threats directed at your applications.
Level 1: Network-Level Protection (L3/L4)
Large-scale DDoS attacks can consume bandwidth and overwhelm network resources even when your applications themselves are functioning normally. Cloud4U filters incoming traffic at the network edge, removing malicious packets before they reach your servers.
- A dedicated IP address or cluster from a protected subnet is assigned to your service.
- Cloud4U infrastructure receives and scrubs incoming traffic directed to this IP.
- Malicious traffic is filtered before it can reach your infrastructure.
- Clean, legitimate traffic is continuously forwarded to your servers.

Level 2: Application-Level Protection (WAF)
Some attacks target the application itself rather than the underlying network. Cloud4U's Web Application Firewall (WAF) provides deep traffic inspection at the application layer (L7), analyzing application traffic and helping to block malicious requests before they reach your web applications.
WAF protection helps reduce application-layer threats and adds an additional layer of security for websites, applications, and sensitive corporate and customer data.
The solution can also help prevent your infrastructure from being misused as a source of attacks against other networks.
