The shift to cloud computing has transformed the way enterprises build and scale their IT infrastructure. But with this transformation comes a new challenge: maintaining security and visibility across environments that span on-premise networks, public clouds, and everything in between.
Your on-premise environment may be tightly monitored—but what about the applications and data running in Amazon Web Services (AWS), Microsoft Azure, or Google Cloud Platform (GCP)? This is the reality for modern hybrid and multi-cloud architectures: traditional monitoring tools were never built for this level of complexity, leaving organizations with a fragmented view of their own networks.
Why Traditional Monitoring Falls Short
Legacy monitoring solutions were designed for static, physical networks. They excel at tracking north–south traffic at the network perimeter but offer limited visibility into:
-
East–west traffic inside cloud environments
-
Cross-cloud communication
-
Traffic flowing between your data center and the cloud
As a result, security teams struggle to detect threats, troubleshoot performance issues, or maintain compliance across environments they can’t fully see.
The Visibility Challenge: Siloed Flow Data
Cloud providers offer their own versions of NetFlow—collectively known as Cloud Flow Logs:
-
AWS: VPC Flow Logs
-
Azure: NSG Flow Logs and VNet Flow Logs
-
Google Cloud: VPC Flow Logs
These logs are extremely valuable, but there’s a catch: each provider collects and analyzes flow data separately. Meanwhile, your on-premise network is generating its own NetFlow data.
This creates a siloed visibility model:
-
On-Premise: Rich NetFlow insights on internal and external traffic
-
Cloud: Flow logs limited to individual cloud environments
-
Hybrid: No unified view of traffic spanning data centers and cloud services
This fragmentation makes it difficult—if not impossible—to trace attacks across environments, understand end-to-end performance, or enforce consistent security policies.
The Solution: NetFlow Optimizer as a Unified Source of Truth
To bridge this gap, organizations need a platform that can ingest, normalize, enrich, and correlate flow data across all environments. This is where NetFlow Optimizer comes in.
NetFlow Optimizer acts as the central hub for hybrid and multi-cloud traffic analysis. It unifies traditional NetFlow data with Cloud Flow Logs from AWS, Azure, and Google Cloud, converting them into a single intelligent data stream.
With a unified visibility layer, you can:
1. Track Traffic Across On-Premise and Cloud
Understand exactly how data moves across your hybrid environment—spot sensitive data transfers, map application behavior, and ensure policies are applied consistently.
2. Monitor User and Application Activity
NetFlow Optimizer enriches raw flow data with context such as:
-
User identities
-
Application names
-
Device attributes
This is critical for detecting lateral movement, unauthorized access, or policy violations anywhere in your infrastructure.
3. Enforce Consistent Security Policies
Unified visibility means you can validate configurations, identify gaps, and maintain compliance without relying on isolated cloud-specific tools.
4. Reduce Noise and Data Volume
Flow data is massive. NetFlow Optimizer intelligently aggregates and filters redundant or meaningless flows, delivering only clean, actionable information to your SIEM or analytics platform.
Making Flow Data Intelligent and Actionable
NetFlow Optimizer doesn’t just collect data—it transforms it. By normalizing logs from multiple cloud providers and combining them with on-premise NetFlow, it delivers a complete and coherent view of your network.
With this unified intelligence, security and operations teams can replace guesswork with clarity, enabling faster detection, better incident response, and more robust compliance in complex hybrid and multi-cloud environments.
Don’t Let the Cloud Fragment Your Security
Hybrid environments shouldn’t mean hybrid visibility. By optimizing and unifying NetFlow and Cloud Flow Logs, you gain the complete, consistent, end-to-end view needed to secure modern distributed networks.
Take control of your cloud visibility. Strengthen your security. Eliminate the blind spots.
