In today’s digital world, the network is the backbone of every business. Data moves across offices, the cloud, mobile devices, and remote endpoints every second. This connectivity drives growth but also gives attackers chances to slip in unnoticed. Visibility now means more than watching traffic—it means truly understanding it. Fidelis Network® Detection and Response (NDR) helps enterprises do exactly that, changing the way they see, defend, and respond to modern threats.
Why Network Visibility is Now Business-Critical
Cybersecurity is a race. Attackers strike fast, while defenders must constantly monitor and respond across large systems. Basic monitoring tools often miss the hidden moves of advanced attackers.
Today’s enterprises face:
- Advanced persistent threats that hide for months
- Ransomware that both locks and steals data
- Insider threats that look like normal activity
- Cloud and mobile risks that widen the attack surface
Without deep, ongoing visibility, these dangers often stay hidden until damage is done. Fidelis NDR helps by giving enterprises eyes and ears across the entire network.
What Makes Fidelis NDR Different
Fidelis NDR is not just another monitoring tool. It is a single platform that combines full network visibility with advanced threat detection. It doesn’t just see activity on the surface; it provides context to understand what’s really happening across the network.
Key differentiators include:
1. Full-spectrum visibility
Fidelis analyzes traffic across all ports and protocols, including encrypted flows. This means security teams can uncover threats hiding in east-west traffic, not just at the perimeter.
2. Deep Session Inspection
Using patented inspection technology, Fidelis can unpack nested files, decode applications, and reveal what’s hidden within sessions—something that traditional packet capture or NetFlow tools cannot achieve.
3. Automated cyber terrain mapping
Fidelis constantly maps assets, data flows, and user activity to create a live model of the network. This helps spot unusual connections, detect sideways movement, and focus on the most important threats.
4. Integration with the broader Fidelis Elevate® platform
Fidelis NDR integrates with other security tools in an XDR setup, sharing threat information across endpoints, cloud systems, and deception layers to provide teams with a comprehensive view of attacks.
From Raw Data to Actionable Defense
The real power of Fidelis NDR lies in its ability to transform massive volumes of raw data into actionable defense strategies. It does this through:
- Advanced analytics and machine learning: Identify normal behavior and flag unusual activity
- Threat intelligence correlation: Match network events with known attack patterns
- Alert enrichment: Combine similar alerts to reduce noise and make investigations faster
- Automated response options: Blocking data exfiltration attempts, quarantining suspicious traffic, or triggering deception techniques
This approach helps organizations detect breaches significantly faster. In fact, Fidelis customers often report finding post-breach activity in a fraction of the time compared to traditional tools.
It also protects networks against today’s most dangerous threats, including:
1. Data Exfiltration
Attackers often try to steal sensitive data quietly. Fidelis NDR spots these attempts by inspecting content deeply, even if the data is hidden or encrypted.
2. Lateral Movement
After breaking in, attackers often move from one system to another. Fidelis NDR uses mapping and behavior analysis to detect unusual connections or privilege misuse before they reach critical assets.
3. Malware on the Wire
Encrypted traffic can hide malware activity. Fidelis NDR decrypts and inspects it in real time, making sure malicious files or attacker communications don’t get through.
4. Cloud and Hybrid Threats
Fidelis NDR also covers cloud environments in hybrid networks, making sure attacks don’t go unnoticed between on-premises and cloud systems.
Why Enterprises Choose Fidelis Network®
Enterprises across industries trust Fidelis NDR for fast, deep network visibility. Key benefits include:
- Fast detection and response limit attacker impact
- High-quality alerts help teams focus on real threats
- Built-in data protection and inspection support regulations

Looking Ahead: The Future of Network Visibility
The future of cybersecurity is predicting threats before they happen. Fidelis NDR uses machine learning, automation, and deception to make this possible.
Emerging trends include:
- Zero Trust integration: continuously verify users and devices
- Post-quantum readiness: keep defenses strong as encryption evolves
- XDR convergence: unify endpoint, network, and cloud data for protection
By investing in deep network visibility today, enterprises stay ahead of threats instead of reacting later.
Conclusion
Fidelis NDR turns network visibility into action, helping teams detect threats fast and improve security continuously. It spots hidden attackers and stops data theft, giving organizations the tools to act confidently and use network visibility as a real defense advantage.
