Data Exfiltration

Data Exfiltration Monitoring: Detect Unauthorized Transfers. Stop Data Loss. Protect Critical Assets.

Gain Visibility into Suspicious Data Movement Across Your Network.

The Challenge

Data Leaves Faster Than Most Teams Can Detect

Attackers and insiders increasingly prioritize stealing sensitive data over pure disruption. Once inside, they move quickly to transfer intellectual property, customer records, credentials, or regulated information to external destinations. Without continuous network security monitoring and data loss detection, these transfers often go unnoticed until the damage is done.

Security teams struggle with:

72 minutes

Time to data exfiltration in the fastest 25% of intrusions in recent incident response data.

22%

Of cases reach data exfiltration in under one hour.

2 days

Median time from compromise to data exfiltration across broader datasets.

The Solution

NetWitness Approach to Data Exfiltration Monitoring

Combining features such as network security monitoring, network threat detection and behavioral analytics, NetWitness can continuously monitor data exfiltration activities in the enterprise. With the help of analysis of network traffic, metadata, session behavior and other related telemetry, it becomes possible to detect unauthorized and suspicious data transfers, understand the situation and act in order to prevent data from being stolen.

Network Visibility for Data Transfer

Analyze north-south and east-west traffic in order to detect abnormal volumes of data transfer to certain destinations via protocols.

Behavioral Detection of Suspicious Data Transfer

Conduct an analysis based on baselining to detect any deviations from normal data flow that could be related to secret or insider-driven data transfer attempts.

Analysis of Encrypted and Cloud Network Traffic

Detect suspicious data transfer attempts to cloud or any other destination despite the fact that traffic is encrypted.

Session Reconstruction and Analysis

Restore certain network sessions in order to understand what kind of data was transferred, when, using what devices or applications and by whom.

Correlated Alerts and Response Assistance

Emphasis on high-fidelity alerts and fast investigation and mitigation of possible data loss incidents.

How NetWitness Data Exfiltration Monitoring Works

Data Loss Detection through a Structured Approach

Continuously collect network traffic, metadata, and related telemetry across on-premises, cloud, and hybrid environments.

Enrich data with behavioral context, protocol analysis, and threat intelligence.

Detect anomalous outbound transfers, unusual volumes, and suspicious destinations using network threat detection and analytics.

Correlate findings with user, endpoint, and log activity for full context.

Investigate session reconstruction and support rapid response to stop ongoing data loss.

The NetWitness Advantage

Benefits

Earlier Detection of Data Transfers

Detect anomalous data transfers before substantial loss happens.

Elimination of Gaps in Visibility

Have insight into encryption and internal data movements.

Greater Investigative Power

Investigate with network forensics.

Less Data Loss

Safeguard sensitive and regulated data.
