The traditional approach of endpoint protection is straightforward. Every device on your network includes an installed security application that monitors, detects, alerts, and remediates. That model worked reasonably well twenty years ago, when most assets that were managed included personal computers and servers. Today, that model is sputtering toward the shelf.

Unfortunately, not everything in the modern IT world can host endpoint protection. In fact, many connected devices are completely unmonitored. Examples include:

• Many IoT and OT devices can’t host traditional security agents
• BYOD and other devices aren’t registered in Active Directory or Azure
• Rogue and shadow IT devices can connect and operate without any standardized protection
• Operational technology such as HVAC equipment, pipelines, and factory machinery

Agent Dependencies

To stop threat actors from moving freely inside your enterprise network, you need a security monitor that operates at the same flexibility. Fortinet’s FortiNDR solution is a fully independent, network‑wide detection engine that isn’t limited by operating systems, device types, or endpoint agents. Instead of relying on software installed on specific machines, FortiNDR performs like a roaming security analyst that quietly observes and analyzes all the conversations happening between devices across your environment.

Perpetual Monitoring and Alerts

Visibility is a basic necessity in all facets of cybersecurity. Think of FortiNDR as that security camera you can install anywhere with no mounting required. It records every suspicious activity such as:

• Odd or anomalous connections
• Large or irregular data transfers to uncommon destinations
• Activities occurring outside normal business hours or patterns inconsistent with typical user behavior
• Legitimate administrative utilities for reconnaissance, lateral movement, or malicious purposes

With FortiNDR, there is no dark alleyway for threat actor to hide. FortiNDR is centered around traffic, not devices. It then shares what it learns with the rest of your security stack so all components respond in concert.

The Relentless Intelligent Detective

Every device on your network, whether known or unknown, leaves breadcrumbs in the form of IP and MAC addresses, protocols, ports, destinations, traffic volumes, and timing. Taken together, this metadata becomes a constantly updated list of active players within your network as well a record of who talked to whom, when, and how often. 

Collecting vast amounts of network data is meaningless without the intelligence to interpret it. This is where FortiNDR’s integrated AI and machine learning capabilities transform raw telemetry into actionable security insights.

• Automatic Asset Discovery: Algorithms powered by machine learning analyze network behavior to identify and classify device types even when they lack proper documentation or network inventory entries. This ensures shadow IT and unmanaged devices don’t create security blind spots.
• Behavioral Correlation: Rather than generating isolated alerts, FortiNDR’s AI correlates related activities across time, users, devices, and protocols to construct complete attack narratives.
• Speed and Scale: While human cannot realistically correlate millions of network events in real time, FortiNDR is designed to do so. The solution’s advanced intelligence capabilities that can process hours of human analysis into minutes.

FortiNDR is the ultimate detective, but at a scale and speed that even Sherlock Holmes couldn’t replicate. With FortiNDR, there are no mysteries within your network.

The Best Ability Is Availability

FortiNDR is available both as an on‑premises platform and as a cloud‑delivered service, which maps neatly to how modern hybrid networks actually operate. For on-prem networks that must adhere to strict compliance and data residency requirements, FortiNDR installs as an appliance or virtual machine that can observe data center workloads, and OT/IoT internal networks. Its agentless approach provides comprehensive visibility into north-south and east-west communications, detecting anomalies, malware, botnets, weak ciphers, vulnerable protocols, and OT or IoT specific threats without relying on cloud submission.

For organizations running hybrid networks or operating with a cloud‑first strategy, FortiNDR Cloud provides a SaaS‑based option that monitors branch offices, remote sites, and public cloud environments. You can even combine on-prem and cloud deployments to keep sensitive segments local while using cloud‑based analytics to scale detection across distributed sites. This unified approach ensures consistent detection logic and AI/ML across both models, giving you a single, coherent view of attacker activity.

The Power Behind FortiNDR

Not only is FortiNDR driven by the power of AI, its also supported by FortiGuard Labs, even if you don’t currently have an existing Fortinet Security Fabric on your network. What makes this so relevant is that FortiGuard continuously collects and analyzes threat data from millions of sensors around the world and feeds those insights into FortiNDR. If you want to know the power of scale, consider this. In 2024 alone, FortiNDR Cloud customers experienced:

• 13.4 trillion network events analyzed, ensuring even subtle anomalies are examined
• 110 million threat observations recorded and correlated to potential attack patterns
• 622,000 detections triggered from confirmed malicious activity or high‑confidence threat indicators
