10 Considerations for Implementing an XDR Strategy
2025 Gartner® Magic Quadrant™ for NDR
July 28, 2025 by Varun Bobhate
In today's complex network environments, ensuring complete visibility while optimizing resource utilization is paramount. Duplicate network traffic can overwhelm your monitoring infrastructure, create redundant alerts for SecOps, consume valuable storage, and obscure critical insights, making it harder for Network Detection and Response (NDR) solutions to spot genuine threats or anomalies. Network Packet Brokers often offer deduplication as a feature but it can add complexity and cost.
We're thrilled to announce a powerful new capability for Corelight’s physical network sensors equipped with our FPGA-based network cards: advanced hardware-based deduplication. This feature is designed to deliver cleaner, more efficient NDR detections, allowing you to focus on what truly matters for your security and operations.
All of this at no additional cost!
Deduplication is a functionality that optimizes network traffic handling by discarding duplicate frames after parsing IP packet header and label or tunnel information contained within that frame.
You might wonder, "Aren't duplicate frames identical?" Not always! Duplicate frames typically traverse the network along different routes, meaning they might arrive with slight variations, such as different MAC source and destination addresses or even different VLAN tags. Corelight's deduplication is configured to compare specific parts of a frame to identify duplicates. When evaluating network traffic, a frame is considered a duplicate if it meets the following criteria:
This sophisticated approach ensures that the system efficiently identifies and processes only the unique data you need for analysis.
The primary benefit of enabling deduplication is to optimize network traffic handling. By intelligently discarding redundant data, Corelight sensors can:
Optimize performance:
Improved detection:
Reduce cost:
Beyond performance, deduplication can also translate into direct cost efficiencies for Network Detection and Response (NDR) deployments. Crucially, our licensing model applies only to traffic after filtering is performed by our Corelight sensor NICs.
In contrast, software-driven NDR solutions may utilize:
While many NDR solutions can leverage external Network Packet Brokers (NPBs), Corelight incorporates this crucial optimization directly within its appliance architecture. This integrated hardware approach offers advantages by not only retaining valuable CPU cycles but by saving additional complexity and licensing costs.
Deduplication is now available in our Corelight software v28.3 release.
This powerful deduplication feature is available on Corelight sensors equipped with an FPGA NIC that has dedup-capable firmware in its active bank. Many of our popular appliances are compatible, including:
The integrated approach of hardware-based deduplication not only provides cleaner data for analysis but also aligns directly with Corelight's capacity-based licensing model, potentially leading to cost savings by reducing the actual monitored traffic volume. Ultimately, Corelight's method ensures a more predictable and efficient network security monitoring experience at scale.
Corelight customers can access configuration details through the deduplication topic on the Corelight documentation site.
