What is ePacketron Packet Data Masking?

ePacketron Packet Data Masking protects sensitive information by masking specified data within network packets before the traffic is forwarded to security, monitoring and analytics tools.

Why is packet data masking important?

Packet data masking helps prevent unauthorized exposure of sensitive information while allowing SOC and NOC tools to retain the packet context required for monitoring, security analysis and troubleshooting.

What types of information can packet data masking protect?

Packet data masking can help protect sensitive information such as personally identifiable information, protected health information, payment card data and confidential business information carried within network traffic.

Where does ePacketron perform data masking?

ePacketron performs data masking within the network visibility layer before packet traffic reaches downstream security, monitoring, packet-capture and analytics tools.

How does data masking differ from packet slicing?

Data masking obscures selected information while preserving the packet structure and surrounding context. Packet slicing truncates packet content beyond a defined length to reduce traffic volume and tool-processing requirements.

ePacketron - Network Intelligence

Network Packet Data Masking with ePacketron

Network packet Data Masking obscures selected information in packet copies before the traffic is delivered to security, monitoring, analytics, or packet-capture tools.

High-Performance Data Masking for Modern Networks

Modern security and monitoring architectures distribute packet-level traffic across multiple tools. That traffic may contain sensitive information that individual tools, operators, or third parties do not need to access.
ePacketron moves Data Masking into the visibility layer, allowing sensitive packet data to be obscured before traffic reaches downstream platforms.

Data Masking

Niagara Networks turns network visibility into a managed traffic intelligence layer - capturing the right traffic, optimizing it for each tool, and protecting mission-critical networks from blind spots and downtime.

312 Gbps Data Masking Performance

ePacketron 5520 delivers 312 Gbps aggregate Data Masking throughput per appliance with IMIX traffic, providing high-performance protection for demanding visibility environments.

Protect Sensitive Information

Mask selected data within network packets before it reaches downstream security and monitoring tools.

Centralize Data Protection

Apply masking policies once in the Network Intelligence layer instead of depending on every downstream tool to independently protect sensitive information.

Preserve Operational Visibility - Data Masking Performance | 312 Gbps Aggregate Throughput per Appliance

Maintain the packet and network context required by SOC and NOC tools while masking information that is not required for analysis.

This high-performance processing allows organizations to apply Data Masking directly within the visibility infrastructure without pushing the processing burden onto downstream security and monitoring tools.

The ePacketron Approach: Data Masking in the Network Intelligence Layer

Traditional monitoring architectures often send complete packet copies to multiple security, monitoring, analytics, and packet-capture platforms. As a result, sensitive information may be unnecessarily distributed and stored across multiple systems.
ePacketron transforms raw network traffic into controlled, actionable intelligence before it reaches the security stack. Defined masking policies can obscure selected packet data while preserving the traffic required for monitoring, troubleshooting, and security analysis.

The result: 312 Gbps Data Masking. Before the Tools.

Capture the traffic

Collect network traffic at high speed without disrupting operations.

Protect sensitive data

Mask confidential information before packets reach security and monitoring tools.

Deliver only what each tool needs

Send each tool clean, relevant traffic while reducing exposure and processing load.

Performance note: 312 Gbps is aggregate throughput measured by Niagara Networks in testing of an ePacketron 5520 using IMIX traffic with Data Masking operating independently. Production performance varies with traffic mix, packet size, policy, configuration, and combined functions. No chained-function throughput claim is made.

Data Masking Where Visibility Begins

ePacketron enables configurable Data Masking as part of Niagara Networks’ advanced Layer 4–7 Network Intelligence architecture.

Selective Data Masking

Mask specified byte ranges within network packets.

Multiple Masks

Apply multiple masking rules where required.

High-Performance Processing

Process Data Masking traffic at up to 312 Gbps aggregate throughput per ePacketron 5520 appliance with IMIX traffic.

Centralized Processing

Apply masking before traffic reaches downstream security, monitoring, analytics, and packet-capture systems.

Integrated Network Intelligence

Combine Data Masking with other ePacketron functions including packet slicing, deduplication, application filtering, RegEx filtering, NetFlow/IPFIX generation, tunnel termination, TLS processing, and other advanced traffic-optimization functions.

Preserve Operational Visibility

Maintain the packet and network context required by SOC and NOC tools while masking information that is not needed for analysis.

Why Mask Data Before It Reaches the Tools?

Moving Data Masking into the Network Intelligence layer creates a centralized policy and processing point between network traffic sources and downstream monitoring infrastructure.
Instead of delivering complete packet data everywhere, organizations can control which information each tool receives. This helps organizations:

• Reduce exposure of sensitive packet data
• Support privacy and compliance strategies
• Limit unnecessary access to sensitive information
• Centralize data-protection policies
• Reduce duplicated privacy controls across multiple tools
• Preserve visibility for SOC and NOC operations
• Offload high-speed Data Masking from downstream platforms
