What is DDoS?

Also known as: Distributed Denial of Service

A distributed denial-of-service (DDoS) attack is a malicious attempt to disrupt the normal traffic of a targeted server, service or network by overwhelming the target or its surrounding infrastructure with a flood of Internet traffic. From a high level, a DDoS attack is like an unexpected traffic jam on a road, preventing regular traffic from arriving at its destination. Distributed Denial of Service (DDoS) attacks are becoming a major risk to service availability of mission critical, internet-based applications. Distributed Denial of Service (DDoS) attacks are becoming a major risk to service availability of mission critical, internet-based applications. DDoS protection blocks threats before they reach you and your firewall protecting your business against revenue loss without the need for expensive hardware, software, or specialists. DDoS protection ensures that your business can effectively manage cyber extortion threats, and that your network and services are available 24 hours a day, seven days a week, 365 days a year.

The key to effective mitigation is the ability to identify and block attack traffic while allowing non-attack traffic to flow through to its intended destination.We provide a full suite of countermeasures that remove attack traffic while enabling the flow of legitimate traffic – providing mitigation from a wide range of attack profiles, from high-volume flood attacks designed to exhaust bandwidth capacity to the most complex volumetric, TCP-state exhaustion and application-layer DDoS attacks.

Our protection methods include identifying and black-listing malicious hosts, IP location-based mitigation, protocol anomaly-based filtering, malformed packet removal and rate limiting (to gracefully manage non-malicious demand spikes). Mitigations can be automated or left to be manually triggered by the customer.
