Creating a seamless, secure client experience
“In our on-premises environment, each security layer was standalone, presented in several dashboards. In Azure, we wanted to focus not only on the available solutions, but also combining their functionalities into a single easy-to-deploy, easy-to-manage, highly secure environment.”
André Beerendonk, Team Manager for IT Operations, VECOZO
“We need providers like Microsoft that we can trust so we can focus on the business. We use Azure DDoS Network Protection and Azure Web Application Firewall on Azure Application Gateway to protect our business-critical workloads and data streams across our environment.”
Marius Matonis, Senior Technical Lead, Elvia
An end-to-end digital transformation
"Understanding the inner workings of a firewall is not our expertise, and with Azure Firewall Premium, it doesn't have to be. We use Azure Firewall Premium to protect Dematic and our customers around the clock, and we can depend on it."
Brandon Bates, Principal Architect, Dematic

Frequently asked questions about Azure DDoS Protection
Distributed denial of service (DDoS) is a type of attack where an attacker sends more requests to an application than the application is capable of handling. This depletes resources, affecting the application's availability and its ability to service customers. Over the past few years, the industry has seen a sharp increase in attacks, which are becoming more sophisticated and larger in magnitude. DDoS attacks can target any endpoint that's publicly reachable through the internet.
DDoS Network Protection, combined with application design best practices, provides enhanced DDoS mitigation features to defend against DDoS attacks. It's automatically tuned to help protect your specific Azure resources in a virtual network. Protection is easy to enable on any new or existing virtual network, and requires no application or resource changes. It has several advantages over the default infrastructure-level DDoS protection, including logging, alerting, and telemetry. See DDoS Network Protection overview for more details.
DDoS Protection is zone-resilient by default, and managed by the service itself. No customer configuration is necessary to enable zone resiliency.
Use DDoS Protection service in combination with a web application firewall (WAF) for protection both at the network layer (layer 3 and 4, offered by DDoS Network Protection) and at the application layer (layer 7, offered by a WAF). Offerings include Application Gateway WAF and other web application firewall apps available in Azure Marketplace.
Public IPs in a Azure Resource Manager-based Azure Virtual Network are currently the only type of protected resource. PaaS services (multitenant) are not supported. See DDoS Network Protection reference architectures for details.
