- Comprehensive Network Monitoring: Azure Network Watcher provides tools to monitor, diagnose, and gain insights into network performance and security across your Azure virtual networks. It enables continuous observation of traffic between endpoints, helping to ensure connectivity and quickly identify issues.
- Traffic Analytics: Network Watcher includes traffic analytics, a cloud-based solution that analyzes flow logs to visualize network activity, identify hotspots, and detect anomalous or suspicious behavior. It helps answer critical questions like who is connecting, from where, which ports are open, and whether there is any irregular or unexpected network behavior.
- Threat Detection: By analyzing flow logs and network activity, Network Watcher can help detect security threats such as unauthorized access attempts, open ports, rogue network connections, and sudden spikes in traffic. This enables proactive security monitoring and incident response.
- Diagnostic Tools: Features like packet capture, connection monitoring, and topology diagrams support troubleshooting, auditing, and compliance efforts. Packet capture can be triggered by alerts to capture suspicious traffic in real time.
- Integration: Network Watcher integrates with other Azure security tools and can export logs for further analysis or visualization in tools like Power BI.
