The solution ensures business continuity and availability of resources for users. It prevents glitches caused by bad traffic while at the same time allowing good traffic through, keeping high availability of resources, applications and services for users. With the use of DDoS protection, even during a serious attack, the traffic does not come to you directly, but is first cleaned up.
AntiDoS from Cloud4U easily integrates with your infrastructure hosted in our cloud based on IaaS model, does not require data transfer and additional configuration, software installation or hardware purchase. Cleanup options are tailored specifically to your facility's requirements.

How it Works?
Cloud4U operates a geo-distributed traffic filtering network with direct connections to TIER-1 operator networks, ensuring fast and reliable filtering of incoming traffic. Our filtering nodes are strategically located in:
Amsterdam, the Netherlands
Frankfurt, Germany,
Tokyo, Japan,
Washington, USA
This global topology enables efficient local traffic filtering at scale, preventing excessive load on core networks and maintaining connectivity even during attacks.
Types of DDos protection
Basic DDoS Protection – Network-Level Defense
Cloud4U’s filtering modules block malicious traffic, allowing only legitimate requests to pass through preventing bandwidth saturation. During an attack, you’ll be assigned a dedicated IP (or cluster of IPs) from a protected subnet. Our system, powered by industry-leading DDoS mitigation hardware, scrubs all traffic directed to these IPs, ensuring only clean traffic reaches your infrastructure.
Our always-on filtering detects and blocks all known DDoS attack types from the very first malicious packet or flow.
Advanced Protection – Application Layer Defense
All connections to your applications pass through our Web Application Firewall (WAF), which analyzes and sanitizes traffic for HTTP/HTTPS, DNS, SIP, and other application-layer protocols. The WAF is customized to your application’s unique requirements.
This solution ensures fast, secure, and reliable delivery of critical web applications while mitigating vulnerabilities. It meets PCI DSS security requirements, provides protection for sensitive corporate and customer data, reduces the risk of your infrastructure being hijacked for attacks.

FAQ
What is a DDoS attack?
A Distributed Denial-of-Service (DDoS) attack is a coordinated cyber assault aimed at overwhelming a target system—be it a server, network, or online service—with a massive flood of internet traffic, rendering it inaccessible to legitimate users. Unlike a traditional Denial-of-Service (DoS) attack, which originates from a single source, a DDoS attack leverages a network of compromised devices, often called a botnet, that simultaneously send a deluge of requests to the target. This orchestrated barrage exhausts the target's resources, such as bandwidth, processing power, and memory, causing disruptions, slowdowns, or total shutdowns of the service. The distributed nature of the attack, with sources scattered across various locations, makes it particularly challenging to defend against and mitigate..
How does a DDoS attack happen?
A Distributed Denial-of-Service (DDoS) attack occurs when a cybercriminal uses multiple compromised computers, known as bots or zombies, to flood a targeted server with traffic. This overwhelming traffic causes the server to become unable to handle legitimate requests, resulting in a denial-of-service to normal users. Here is a step-by-step explanation of how a DDoS attack happens:Botnet Creation: A hacker creates a botnet by infecting multiple computers with malware, often through unpatched vulnerabilities or phishing attacks. These infected computers become part of the botnet, which can be controlled remotely by the hacker. Target Identification: The hacker identifies a target server or network resource to attack. This can be a website, a server, or any other online system. Attack Command: The hacker issues a command to the botnet, instructing the compromised computers to send a large volume of traffic to the targeted server simultaneously. Traffic Overload: The botnet sends a massive amount of traffic to the targeted server, overwhelming its resources and bandwidth. This can include various types of traffic, such as HTTP requests, UDP packets, or ICMP packets. Server Overload: The targeted server becomes unable to handle the excessive traffic, leading to slow performance, crashes, or complete unavailability to legitimate users. DDoS attacks can be difficult to defend against without proper detection and mitigation tools. Effective defenses include continuous monitoring, real-time alert systems, and the ability to block IP addresses and isolate targeted systems.
What layers of the OSI model are attacked during a DDoS attack?
DDoS attacks can target various levels of the OSI model, each with its own protocols and functions. Some of these levels and types of attacks include:
- Physical layer attacks, such as attacks on cable connections or physical devices.
- Data link layer attacks, related to exhausting the content address table, spoofing, MAC address substitution, and VLAN attacks.
- Network layer attacks, aimed at disrupting data routing and may include attacks on DNS servers.
- Transport layer attacks, aimed at disrupting data transmission between devices, including attacks on TCP and UDP protocols.
- Session layer attacks, aimed at disrupting session management, including attacks on login and logout protocols.
- Presentation layer attacks, aimed at disrupting data conversion into the required format, including attacks on encoding and protocols such as JPEG, PNG, and ASCII.
- Application layer attacks, aimed at disrupting application functionality, including attacks on HTTP, HTTPS, FTP, and SMTP.
What types of DDoS attacks are there?
DDoS attacks are divided into:
Low-level attacks: flood-based attacks (such as synchronized SYN floods and other reflection attacks, like UDP user datagram packet floods), which overload resources with a large number of requests. Attacks that exploit vulnerabilities in the network protocol stack.
High-level attacks: application-level attacks, which target disrupting application functionality (These attacks usually have a large volume and are aimed at overloading the network or application servers). Session-level attacks, which target disrupting session management.
How can you protect yourself from DDoS attacks?
Protection measures:
What are the consequences of a DDoS attack?
A DDoS attack can have the following consequences:
How does DDoS protection work?
DDoS protection works by monitoring traffic and blocking suspicious requests to prevent resource overload. It can be implemented using a cloud-based model without requiring specialized equipment on the customer's side. DDoS protection services typically include setting up monitoring and traffic filtering rules, as well as a dedicated team of experts with practical experience in protecting against cyberattacks.
What is the cost of DDoS protection?
The cost of DDoS protection can vary depending on the type of protection, provider, and resource volume.Types of DDoS protection:
The main factors influencing the cost are: resource volume, type of protection, chosen provider, and the level of complexity of DDoS protection.
.How to determine if it's a DDoS attack?
You can determine if it's a DDoS attack by the following signs:
- Sudden increase in traffic to the resource.
- Increased load on the resource, exceeding its bandwidth capacity.
- Multiple requests from a single IP address.
- Anomalous requests that do not conform to standard requests.
- Sudden increase in server errors, such as 500 or 503 errors.
- Increase in resource response time.
- Sudden increase in the number of requests to the resource.
- Sudden increase in database load.
- Sudden increase in server log errors.
What is the role of CDN in DDoS protection?
A CDN (Content Delivery Network) can play a crucial role in protecting against DDoS attacks, as it can help distribute traffic and reduce the load on the resource. A CDN can protect a website from DDoS attacks, especially if it uses static content and GET requests.
