Data Exfiltration

Early detection is the first step to containment

CHALLENGES

Data exfiltration hides in plain sight.

A steady, high-volume data stream to an external endpoint is easy to miss unless someone measures the volume, duration, and destination for every session in every environment.

Hybrid and multi-cloud networks give attackers more places to work unseen. Data moves between on-prem data centers, co-location facilities, and cloud providers – each with its own tools and blind spots. Without consistent visibility, teams detect too late, struggle to scope what was taken, and leave the door open for future breaches.

Meanwhile, dwell times linger, more customer PII is compromised, business disruption worsens, and regulatory exposure increases.

OUTCOMES

How packet-level visibility can improve your security posture

Faster Detection

Flag sustained, high-volume transfers to external endpoints while the session is still open – not after the data is gone.

Complete Incident Scope

Know which server was targeted, which client pulled the data, how much was exfiltrated, for how long, and over which protocol.

Immutable Evidence That Attackers Can't Erase

Retrieve the original packets for forensic analysis, legal holds, and compliance audits – independent from logs that can be tampered with.

Response Inside Existing Workflows

Route exfiltration alerts to the dashboards, incident tools, and notification channels your NOC and SOC already use.

SOLUTIONS

Explore how cPacket can help you solve this challenge.

TRADITIONAL SOLUTION

Traditional cPacket Solution

cPacket turns every packet entering and leaving your network into session-level evidence.

cVu packet brokers deliver lossless, deduplicated ingress and egress traffic from on-premises, colocation, virtual, and multi-cloud environments to cStor appliances, which capture both directions and characterizes each client-server session at line rate.

cClear Control Center brings every environment into a single view and alerts your incident tools when a session's running total crosses a threshold you set. Analysts download the PCAP, identify the client, server, and protocol, and close the security hole.

REQUIRED PRODUCTS

KEY FEATURES

Session-Level Exfiltration Metrics

Measures ingress and egress traffic for every client-server session – bytes, duration, bandwidth, and a running total – so large outbound transfers stand out from normal activity.

Threshold Alerting to Incident Tools

Set volume thresholds, such as 5 GB per session. cClear notifies its dashboard, email, text, Datadog, or ServiceNow as soon as a session exceeds them.

Simultaneous Capture and Retrieval

Investigators can query and retrieve the exact packets they need – while cStore appliances continue recording and analyzing every packet at up to 200 Gbps.

AI SOLUTION

Right tool

cPacket AI Workflow

Hunt for exfiltration in plain language, with answers grounded in packet data.

cPacket MCP servers expose cStor session analytics and enriched cClear data to the LLM your organization already uses. Ask it to find exfiltration between internal servers and external clients, and it analyzes ingress and egress session volume, duration, and destinations across the network to return every matching condition.

REQUIRED PRODUCTS

KEY FEATURES

Natural-Language Threat Hunting

Ask the LLM to check for exfiltration and get back the internal servers, external endpoints, and transfer volumes involved – without writing queries or building dashboards.

Packet-Grounded Evidence

The model reasons over session metrics derived from lossless packet capture, so every finding traces back to wire-level evidence your team can verify.

Open, Private integration

cPacket MCP servers ship today and connect to your existing AI platform while network telemetry stays inside your environment.

Frequently Asked Questions

Get answers to common questions about network observability and cPacket solutions.

What is data exfiltration?

Data exfiltration is the unauthorized transfer of data from enterprise-controlled systems. It may occur through direct file transfer, cloud-to-cloud synchronization, abuse of legitimate collaboration tools, database export, APIs, remote-access tooling, or compromised third parties.

Does cPacket replace my NDR, SIEM, or DLP tools?

cPacket complements your security stack by making them run more efficiently. cVu feeds deduplicated, filtered traffic to NDR, IDS, and SIEM tools, while cStor adds session analytics and lossless capture for detection and forensics.

How can I detect exfiltration in encrypted traffic?

For volume-based exfiltration patterns, cPacket can help teams detect movement of encrypted data. Detection relies on session metadata – bytes, duration, bandwidth, and endpoints – that remains visible without decrypting payloads.

Can I detect data exfiltration across cloud environments?

cPacket’s observability solutions provide a 360-degree, packet-level view across network segments. We offer physical appliances for on-prem deployments and agentless solutions for virtualized and cloud environments.

How do exfiltration alerts reach my team?

cClear sends notifications to its dashboard, email, text, and third-party platforms such as Datadog and ServiceNow. Analysts can open the incident and download the PCAP to investigate.
