Datadog is a cloud platform for monitoring and securing infrastructure and applications. It covers observability for infrastructure, applications, logs and data, digital experience monitoring, software delivery tooling such as CI visibility and testing, and service management with incident response. Datadog also offers security products, including cloud security, code security and a cloud SIEM. The service is delivered as a hosted platform and used through a web application, while a Datadog Agent runs on the monitored systems. The user-space components of that agent are published under the Apache 2.0 licence.
Datadog, Inc. was founded and is headquartered in New York City and is listed on Nasdaq, so US jurisdiction applies, which is relevant for the CLOUD Act. Customers choose a regional site: the EU1 site is located in Germany, while other sites are in the US, Japan, Australia and the United Kingdom. Datadog lists AWS, Google and Microsoft Azure as infrastructure subprocessors, all US companies. The platform itself is closed source and operated by Datadog.
