Why Enterprises Choose Fidelis NDR to Stay Ahead of Advanced Cyber Threats

Today’s cyber threats are smarter and more targeted, using advanced tactics like AI malware and data theft. Traditional tools often fall behind due to limited visibility and outdated detection. Fidelis NDR gives organizations clear visibility and smart detection to stop attacks early.

The Need for a Proactive Security Approach

Cyberattacks are no longer simple break-ins. Threats like APTs, ransomware, and hidden malware are now more precise and built to stay unnoticed in systems for a long time.

Key cybersecurity challenges faced by enterprises today include:

• Complicated networks spread across cloud, on-site, and remote systems
• More attackers using encrypted traffic to hide threats
• High false-positive rates from traditional detection tools
• Limited visibility into east-west (internal) traffic
• Slow and disjointed response processes

A reactive approach to security is no longer enough. Organizations must shift toward continuous visibility, faster detection, and coordinated response — all of which are core strengths of Fidelis Network Detection and Response (NDR).

What Makes Fidelis NDR Stand Out

Fidelis NDR is not just another detection tool. It is a fully integrated platform built to uncover threats in motion, provide deep insights, and support automated defense actions.

Let’s take a closer look at what sets Fidelis NDR apart:

1. Full Visibility Across the Network

Fidelis NDR provides:

• Deep visibility across all ports, protocols, and applications
• Session-level analysis for both inbound and outbound traffic
• Monitoring of encrypted, compressed, and nested data

Its Deep Session Inspection looks deeper than basic traffic tools by rebuilding full sessions and examining hidden content in files and traffic. This helps security teams spot advanced attacks that are often missed.

2. Intelligent Detection at Scale

Instead of just using fixed signatures, Fidelis uses several detection methods including:

• Machine-learning-based anomaly detection
• Network behavior analytics
• Threat intelligence from multiple sources
• Retrospective detection using stored metadata

Fidelis NDR gathers 300+ metadata attributes per session, giving teams deep visibility to investigate threats and review past activity with new intelligence.

3. Automated Alert Correlation and Threat Mapping

Fidelis reduces alert overload by grouping related alerts and providing clear, detailed information. This includes:

• Mapping alerts to the MITRE ATT&CK framework
• Presenting correlated indicators of compromise (IOCs)
• Highlighting affected assets and potential lateral movement

This automation helps teams investigate faster and decide quickly, even in emergencies.

4. Real-Time Threat Protection Across Use Cases

Fidelis NDR is designed to protect against many types of threats, including:

• Data Exfiltration

Using advanced inspection, Fidelis detects data leaving the network through covert channels. It can:

• Identify deeply embedded exfiltration attempts
• Prevent unauthorized transfer of sensitive data
• Apply Network Data Loss Prevention (DLP) rules across traffic
• Malware in Transit

By analyzing encrypted and unencrypted traffic, Fidelis identifies:

• Malware hiding in encrypted channels
• Command-and-control communications
• Harmful files and unusual behaviors

The platform uses sandboxing to run suspicious files safely and watches how they behave.

• Lateral Movement

Attackers often move quietly within a network before striking. Fidelis helps stop this with:

• Cyber terrain mapping that shows how assets are connected
• Detection of unusual movement patterns across internal systems
• Identification of compromised hosts or credentials

Other main features and technologies include:

• Threat Intelligence Integration: Uses shared data, Fidelis info, and custom rules to spot threats
• Protocol Decoding: Parses and analyzes application-specific data

5. Supporting Modern Enterprise Environments

Fidelis Network® is built for flexibility and scale. It supports:

• On-premises deployment with physical or virtual appliances
• Cloud deployments, either customer-managed or Fidelis-managed
• Compact 1U sensors for high-speed processing in minimal space

Its deployment options ensure that organizations with diverse infrastructure models — from traditional data centers to fully remote teams — can maintain consistent protection.

6. Part of a Broader XDR Strategy

While powerful as a standalone solution, Fidelis NDR is also a key component of the Fidelis Elevate® XDR platform. When integrated with endpoint and deception technologies, it allows organizations to:

• Correlate data across multiple security layers
• Unify incident detection and response workflows
• Maintain comprehensive visibility across cloud, network, and endpoints

This wider integration helps resolve issues faster and reduces blind spots in complex IT environments.

Strategic Benefits for Enterprise Security Teams

Organizations pick Fidelis NDR because of its strong features and how it helps improve security work in real ways. Benefits include:

• Faster post-breach detection — customers report 9x quicker detection times
• Reduced alert fatigue and more accurate triage
• Greater visibility into encrypted and internal traffic
• Confidence in regulatory compliance and data protection

Security leaders also gain from the platform’s fit with business continuity goals. With clearer visibility, quicker detection, and useful context, handling incidents becomes more planned and less rushed.

As threats get smarter, companies need better tools. Fidelis NDR provides clear visibility, smart automation, and real-time insights to stop attacks early and protect businesses.
