Unlocking Hybrid Network Visibility with Azure Flow Logs

Unlocking Hybrid Network Visibility with Azure Flow Logs

Are you struggling to maintain full network visibility across your hybrid environments? If so, you’re not alone. As workloads shift from on-prem to the cloud, network teams find themselves battling blind spots as they monitor, troubleshoot, and optimize network performance. But what if you could achieve complete observability and overcome the limitations of both legacy network monitoring and cloud-native monitoring tools? 

This is one of the reasons we’re excited to introduce Azure Flow Logs Support for ElastiFlow NetObserv, empowering enterprises with the insights they need to monitor, troubleshoot, and optimize their Azure environments with ease.

Why Hybrid Network Visibility Is a Growing Challenge for NetOps & SecOps

Cloud migration introduces a new set of challenges for NetOps and SecOps teams. Traditionally, teams have relied on tools like NetFlow, IPFIX, and SNMP to monitor on-prem network performance. However, when extending operations to the cloud, they often run into roadblocks that can slow down troubleshooting and potentially increase security risks. The obstacles include: 

  • Siloed monitoring tools. Legacy solutions lack cloud support, requiring teams to switch between different platforms.

  • Partial flow visibility. Azure-native solutions like Network Watcher only show one side of network flows, leaving gaps in visibility.

  • Data correlation and troubleshooting issues. Without aggregated network intelligence, diagnosing security threats or performance issues becomes complex and time-consuming.

These gaps make it harder to secure cloud environments and quickly spot performance and security issues. Fortunately, there is a different approach that helps solve these challenges. 

Introducing Azure Flow Logs Support for ElastiFlow NetObserv

ElastiFlow reduces network blind spots by unifying visibility across the entire network within a single solution. No more juggling disjointed monitoring tools to understand your network traffic. The latest enhancement delivers: 

  • Full hybrid network observability. Monitor network activity across both on-prem and Azure environments within a single dashboard.

  • Real-time insights and security enrichment. Identify security threats with NetIntel-powered threat intelligence and ML-driven flow log analysis.

  • Simplified cloud migration and app dependency mapping. Ensure seamless application performance when migrating workloads between on-prem and the cloud.

  • Optimized cloud egress costs. Analyze Azure flow data to reduce unnecessary cloud spend and improve network efficiency.

  • Eliminate visibility gaps. Unlike Azure Network Watcher, ElastiFlow correlates end-to-end network traffic, no matter where the assets are located, ensuring a comprehensive view.

How Does It Work? 

ElastiFlow ingests Azure Flow Logs using an efficient, real-time event hub integration. It then processes, enriches, and standardizes this data,  ensuring seamless correlation with other network telemetry sources such as NetFlow, sFlow, and IPFIX.

The enriched data is made available in prebuilt dashboards that provide deep insights into your cloud traffic, performance trends, and security risks. As a result, you can stop wasting time digging through disjointed data and start making faster decisions. 

Why Now? The Impending NSG Flow Log Retirement

Microsoft has announced that customers will no longer be able to create new NSG flow logs starting June 30, 2025. NetObserv supports Azure’s VNet logs and supports all additional fields, leading to not only a future-proof solution but also more detailed observability, Key takeaway – without the right observability tools, teams risk losing critical network visibility. 

By leveraging ElastiFlow’s Azure Flow Logs Support today, organizations can future-proof their network monitoring strategy and avoid disruptions down the road.
