Detect Threats and Prevent Data Loss with Network Traffic Analysis

Detect malicious behavior, identify traffic anomalies, and automatically respond to advanced threats.

Eliminate Blind Spots With Network Traffic Analysis

Watch this short video to learn how Fidelis Network:

  • Automatically discovers and classifies network assets
  • Delivers unmatched visibility across all ports and protocols
  • Detects threats via powerful machine learning analytics
  • Enables threat hunting based on rich metadata
  • Prevents sensitive data from leaving your network
  • Automates threat response at the endpoint

Identifying threats and data leakage requires deep inspection, extraction, and analysis of all forms of content. Fidelis provides network traffic analysis that bi-directionally scans all traffic, regardless of port or protocol, to reveal the network and application protocols, files, and content. With direct, internal, email, web and cloud sensors, you gain full network coverage and visibility.

Read the data sheet for an overview of Fidelis Network.

Never Miss an Attack or Data Leaving Your Network

  1. Gain real-time visibility across all ports and protocols via patented Deep Session Inspection®
  2. Utilize rich rich network metadata for security analytics, machine learning, investigations, and threat hunting
  3. Automatically discover and classify data, tag content and detect behavior anomalies to ensure data loss prevention

Map Your Cyber Terrain

Automatically profile and classify IT assets and services including enterprise IoT, legacy systems and shadow IT to map your cyber terrain. When integrated with Fidelis’ endpoint detection and response solution, you gain a software asset inventory correlated with known vulnerabilities including CVE and KB links, as well as security hygiene for patches and endpoint status. You can even import third party external sources to enrich your cyber terrain knowledge.

Deep Visibility Across Your Network Security Stack

  1. See bi-directional traffic across all ports and protocols
  2. Conduct PCAP or real-time layer 7 analysis
  3. Decode content by protocol or application
  4. Gain deep and wide visibility with sensors for direct, internal, email, web and cloud traffic
  5. Automatically profile assets and your cyber terrain
  6. Leverage rich indexed metadata for over 300 attributes
  7. Tag content with custom tags
  8. Store metadata on-premises/cloud for retrospective analysis

Detect and Prevent Threats with Network Traffic Analysis

Automate the detection of attackers, suspicious hosts and malware with real-time analysis of content and context, as well as the identification of behavioral anomalies. Fidelis Network provides multiple sensors that can be placed throughout your network to detect advanced threats and enforce prevention policies.

Multiple Defenses in One Network Traffic Analysis Solution

  1. Prevent threats with behavior rules, signatures, threat intelligence feeds, heuristic techniques, and more
  2. Detect threats via sandboxing, network behavior analysis, machine learning anomaly detection, curated threat intelligence, and more
  3. Hunt for threats with content analysis and indexed metadata
  4. Profile TLS encrypted traffic to determine human browsing versus machine traffic

Data Loss Prevention

Fidelis prevents sensitive data from leaving your network by providing deep visibility of content and classifying data with pre-built policies to alert for policy violations of known compliance regulations across network, email and web sensors.

See Everything Leaving the Network

  1. Prevent data leakage with email security that includes pre-click analysis of URLs, attachment analysis, and OCR image to text analysis
  2. Run security analytics based on high and low frequencies, as well as sequencing analysis
  3. Drop network or web sessions, control email attachments, and redirect web pages

"We’re able to observe more – more aspects, more activities and more methods used during an attack. Thanks to Fidelis our security dramatically changed."

- IT Director, Marek Laskowski, DZP

Eliminate Alert Fatigue and Automate Response

Fidelis Network automatically validates, correlates, and consolidates network traffic analysis alerts against every Fidelis managed endpoint in your network. Minimize false positives and shift from clues to conclusions so you can quickly address the alerts that matter most.

Focus On What Matters

  1. Derive conclusions with aggregated alerts, context, and evidence
  2. Expose misuse of assets and encryption, and discover proxy and security circumvention
  3. Prioritize based on risk scoring, behavioral and historical analytics, and policy and alert management
  4. Integrate with your security stack via an open policy interface, along with the ability to send alerts and data to your SIEM or SOAR

Network Traffic Analysis: The Cornerstone of Your Security Stack

Fidelis Network provides the rich metadata as the DNA to understand content, context and behavior across your mapped cyber terrain. From there you can build upon this cornerstone adding deception and endpoint detection and response.

Classify, Prevent, Detect, Investigate and Respond

  1. Automatically profile assets and deploy decoys and breadcrumbs
  2. Understand TLS encrypted traffic anomalies, plus human versus machine traffic profiles to detect malware and C2 communications
  3. Quickly search and query rich metadata from network sensors and endpoint agents to hunt for threats
  4. Automate detection, investigations and response with pre-built scripts and playbooks
  5. Leverage open source threat intelligence and apply it across network sensors and endpoints

Powerful Threat Research Drives Accurate Detection

With Fidelis Insight you can rapidly detect and respond to threats in your environment – even when they occur in the past. Advanced detections are created by analyzing real-time and historical data, sandboxing files, and applying machine learning analysis.
