DDoS Protection

What is a DDoS attack?

Chances of becoming a target for DDoS attack are very high, and there are many such attempts. Goal of a DDoS attack is to make the server, service or infrastructure unavailable by overloading the server’s bandwidth or monopolizing its resources until it is completely exhausted. During a DDoS attack a large number of requests are simultaneously sent from a large number of hosts across the entire Internet. The intensity of such a "crossfire” makes the provided service unstable, and unavailable in worst cases.

Goals and types of attacks

There are three ways to make your site, server or infrastructure unavailable:
• Overload network bandwidth of the server, making it unavailable.
• Exhaust system resources of the machine, making it impossible to respond to legitimate
requests.
• Exploit a software vulnerability to gain control of the machine or limiting access to it.

How servers are protected

To protect servers and services from attacks we offer a VAC-based solution, a unique combination of methods for:
• High-speed analysis of all packets in real-time
• Incoming server traffic filtering
• Mitigation of negative consequences by blocking all illegitimate IP packets
