**DDoS Protection** is an [Firewall](/en/documentation/products/secure/firewall/) add-on that protects your applications against *Denial of Service (DoS)* and *Distributed Denial of Service (DDoS)* attacks, at the network, transport, presentation, and application layers (layers 3, 4, 6, and 7 of the OSI model, respectively).
**DDoS Protection** is a [Firewall](/en/documentation/products/secure/firewall/) add-on that protects your applications against *Denial of Service (DoS)* and *Distributed Denial of Service (DDoS)* attacks, at the network, transport, presentation, and application layers (layers 3, 4, 6, and 7 of the OSI model, respectively).

At Azion, DDoS Protection is **unmetered** and is automatically enabled in all accounts. It offers protection against DoS and DDoS attacks with unmetered bandwidth. This means that, no matter how much DDoS attack traffic is directed to your applications or the Azion infrastructure, the Azion dedicated network will guarantee that all services are constant and not affected by the attack. As it's unmetered, mitigation using this protection won't appear on *billing*. For more information regarding traffic accounting, see the [pricing](/en/documentation/products/pricing/) page.

### Always-on mitigation

**DDoS Protection** is *always-on*. It's continuously monitoring the network flow by inspecting incoming traffic. It also provides advanced traffic analysis and signature algorithms to detect and block malicious traffic in time and with no impact on your applications. It also uses Deep Packet Inspection (DPI) and Artificial Intelligence (AI) algorithms to detect abnormal traffic behavior for accurate detection, reducing false positives.

You can also optimize protection against DDoS attacks at the application layer (layer 7) using [Web Application Firewall](/en/documentation/products/secure/firewall/web-application-firewall/), an [Firewall](/en/documentation/products/secure/firewall/) add-on.
