Datadog App and API Protection offers a robust security solution by integrating with popular edge proxies and load balancers like Envoy, Istio, NGINX, and Google Cloud Load Balancers, including HAProxy support in Preview. This integration allows for real-time threat detection and blocking at the network edge, preventing malicious requests from reaching applications and consuming resources. By inspecting all incoming traffic, the system enables both inline blocking and asynchronous monitoring, offering deep visibility into API activity and potential threats without latency. The solution also maintains an up-to-date inventory of endpoints, providing valuable insights into public exposure, authentication methods, and attack activity. Pairing edge protection with in-app instrumentation creates a layered defense, enhancing security by blocking threats at both the network edge and within application code execution. Datadog's unified security approach allows real-time action on detected threats, offering comprehensive protection across various environments while simplifying deployment and ensuring consistent protection across VMs, containers, and microservices.
