# DDoS Protection

Global, automated and secure: a worldwide Anycast network that absorbs Layer 3/4 attacks, monitored and managed 24/7.

When attackers target your infrastructure directly by IP address, they try to flood
your network and bypass the protections in place. Our **DDoS service** intercepts the
threat and scrubs the traffic at the edge, so only legitimate requests reach you and
your websites and applications stay available.

*Volumetric attacks are absorbed at the edge, closest to the source, clean traffic continues to your origin.*

- Legitimate users (Worldwide)
- DDoS flood (Layer 3/4)
- Optimi Edge
- Traffic delivered (Apps stay online)
- Attack absorbed (Mitigated at source)

## Smart, automatic and dynamic

- **Cloud Based** — A cloud-based solution with scalable capacity, instant attack detection, and mitigation closest to the source, keeping your network resources available even under the largest attacks.
- **Network Capacity** — Network attacks are unpredictable and hit your business immediately. A large-capacity network reduces the risk of harm, protecting its own backbone by default.
- **Automatic** — Easy to manage and requires no active oversight. Most common attack types are mitigated automatically with no human intervention, so your business stays protected.

> **Stay live, stay profitable**
>
> Downtime costs money. Automatic mitigation keeps your site live through an attack so
>   you never lose revenue to an outage you did not cause.

## Main features
