+# Agent Check: Tailscale
+
+## Overview
+
+[Tailscale][1] is a peer-to-peer VPN service that simplifies and secures network connectivity.
+
+With this integration, you can:
+
+1. Control your Tailscale data retention.
+2. Build custom widgets and dashboards.
+3. Setup your own or leverage out of the box detection rules
+4. Cross-reference Tailscale events with the data from other services in your stack.
+
+This integration streams two log types from Tailscale:
+
+[Configuration Audit Logs][4]:
+
+Configuration audit logs let you identify who did what and when in your tailnet. These logs record actions that modify a tailnet's configuration, including the type of action, the actor, the target resource, and the time.
+
+[Network Flow logs][5]:
+
+Network flow logs tell you which nodes connected to which other nodes and when on your Tailscale network. You can export network logs for long-term storage, security analysis, threat detection, or incident investigation.
+
+After parsing your Tailscale logs, Datadog then populates the out-of-the-box Tailscale overview dashboard with insights into security-related events from your physical and virtual traffic.
+
+## Setup
+
+### Installation
+
+The Tailscale check is included in the [Datadog Agent][2] package.
+No additional installation is needed on your server.
+
+### Configuration
+
+To enable log streaming:
+
+1. Login to your Tailscale admin console
+2. Navigate to the Logs tab
+3. Select the **Start streaming** button
+From the menu, select Datadog and add a URL + token or [API key][6]
+4. Select the **Start streaming** button
