Network Traffic Analysis

Attackers Can Sneak Past 
the Best Defenses

If your organization is like 96% of organizations,  then malware and attackers have already infiltrated your network. To prevent data loss, you need to detect these breaches quickly— before attackers have the time to move around your network and steal or destroy data.


Most Networks Have Strong
Perimeters, Weak Centers

Most organizations focus on stopping attacks at the network perimeter, but they overlook attackers already in the network. As a result, once malicious users have established a foothold, they can easily perform reconnaissance and exfiltrate data. Attackers can disable logging and endpoint protection after they’ve taken over machines, and they can use remote access and management tools to move laterally, while evading intrusion detection systems.

With the median dwell time—the time required to detect a breach—hovering around 146 days, organizations need a better way to detect attacks.

Network Traffic Analysis 
Finds Breaches Early

Network Traffic Analysis (NTA) closes the gap in breach detection by analyzing network traffic and detecting threats not seen by other security devices. More specifically, NTA leverages machine learning to model the behavior of every user and every device, including mobile and IoT devices. From this baseline of known good behavior, NTA detects anomalies that indicate an attack.

Broad Coverage Reduces
Attack Opportunity

Alternative detection technologies leave gaps in visibility that allow attackers through. In contrast, Network Traffic Analysis:

  • Analyzes packets in near-real time, to spot all threats and to find attacks that netflow-based solutions miss.
  • Examines traffic from every networked device, such as printers, VoIP equipment, mobile phones, unmanaged laptops, and medical devices, to spot behavior that agent-based solutions can never see.
  • Inspects traffic in corporate networks, branch offices, and cloud environments to monitor and protect all business assets irrespective of log settings or normalization.

Endpoint Analysis Verifies Attacks

Network Traffic Analysis discovers a wide range of threats, identifying some as definitive attacks and others as suspicious—but unconfirmed—risks. To take the guesswork out of reviewing alerts, Network Traffic Analysis solutions can analyze endpoints automatically to determine which applications generated suspicious traffic.  Once identified, questionable files can be detonatead in a virtual sandbox and examined by virus scanning engines to determine if they are malicious.
