The Solution: Intelligent Flow Monitoring
Corelight, the fastest-growing leader in network detection and response (NDR), announced the launch of Flow Monitoring for AWS environments, transforming how security teams handle AWS Virtual Private Cloud (VPC) flow data. By intelligently processing VPC flow logs, Corelight reduces SIEM and storage costs by up to 90% through intelligent filtering, deduplication, and enrichment without sacrificing security-relevant detail.
Three Game-Changing Benefits
1. Comprehensive Network Visibility
- Captures traffic across virtual, containerized, and cloud workloads
- Combines deep packet network activity analysis
- Eliminates blind spots in network monitoring
- Ensures complete coverage of potential attack surfaces
2. Dramatic Cost Reduction
Up to 90% cost reduction in SIEM and storage costs through intelligent filtering, deduplication, and enrichment while maintaining critical security-relevant details. This addresses the overwhelming volume of low-fidelity logs that previously made VPC Flow Logs impractical for SOC workflows.
3. Faster Threat Investigation
Accelerates threat detection and response by 2X through standardized Zeek-format data enriched with threat intelligence, community IDs, and cloud asset metadata, enabling analysts to pivot seamlessly across network evidence.
How It Works: Unified Telemetry
Zeek Normalization Advantage
Unlike other NDR solutions that treat cloud and on-premises data separately, Corelight Flow Monitoring normalizes diverse flow data, including AWS VPC Flow Logs, into a consistent Zeek format. This unified telemetry enables:
- Consistent detection logic across hybrid environments
- Standardized dashboards and workflows
- Elimination of custom integrations or parsing
- Consistent queries and detection pipelines
- Dramatically improved SOC efficiency
Industry Recognition and Validation
Analyst Perspective
“In the past, customers who enabled VPC Flow Logs rarely used this data in their SIEM or SOC workflows due to the overwhelming volume of low-fidelity logs,” said Christopher Kissel, IDC research vice-president, Security & Trust Products. “Corelight changes this equation by delivering high-fidelity, security-enriched data at a fraction of the volume and cost, making comprehensive AWS threat detection both practical and affordable.”
Executive Vision
“Security teams operating in AWS shouldn’t have to choose between comprehensive visibility and cost control,” said Vijit Nair, vice president of product at Corelight. “Our Flow Monitoring solution transforms high-volume, low-context AWS flow data into enriched, security-ready intelligence that dramatically reduces costs while also improving detection capabilities.”
Forrester Recognition
Corelight was recently named a Leader in The Forrester Wave™: Network Analysis and Visibility Solutions, Q4 2025, receiving the highest score possible in deployment and administration criteria, reflecting the solution’s flexible deployment options and ease of management.

The Broader Cloud Security Context
Rising Threat Landscape
Attackers increasingly target cloud-native architectures with sophisticated lateral movement techniques. Organizations require scalable, cost-effective solutions providing consistent visibility across complex hybrid ecosystems.
NDR as Critical Infrastructure
Network Detection and Response is emerging as essential for cloud security strategy, providing the network context that other security tools miss—particularly for detecting lateral movement, insider threats, and advanced persistent threats that evade perimeter defenses.

The Future of Cloud Security Monitoring
As cloud adoption accelerates and attack surfaces expand, intelligent flow monitoring becomes essential infrastructure. Corelight’s approach transforms the traditional trade-off between visibility and cost into a win-win: comprehensive security monitoring that’s both more effective and more affordable.
By eliminating the visibility gaps inherent in native flow logs while dramatically reducing data volumes, Flow Monitoring enables security teams to finally leverage AWS VPC Flow Logs effectively—turning them from unused infrastructure logs into actionable security intelligence.
