NDR
NDR belongs to the Network Security area. NDR analyzes network traffic to detect anomalies, lateral movement, and behavior that endpoints or firewalls may miss. It works mainly with flows, packets, and metadata.

What This Technology Covers
NDR analyzes network traffic to detect anomalies, lateral movement, and behavior that endpoints or firewalls may miss. It works mainly with flows, packets, and metadata.
Why It Matters
It is useful for organizations that need visibility across data centers, branches, cloud, or OT environments.
In practice, this is not only a technical function. It is a way to place the solution into a broader security architecture. Many organizations operate dozens of consoles and tools, so the challenge is also to understand which technology solves which type of risk.
This category helps name the problem precisely, narrow the list of relevant solutions, and distinguish technologies that may look similar at first glance. That is useful for partners and customers who already understand cybersecurity but need a clear map of the market and available portfolio.
Typical Use Cases
NDR is usually considered when an organization needs tighter control over a specific security layer within Network Security. It can complement an existing architecture, replace an outdated tool, improve visibility, or consolidate functions currently split across multiple products.
Place In The Architecture
Within the broader Network Security architecture, NDR should be assessed by how it connects to existing security and operational processes. Its practical value appears when the solution provides usable data, clear policies, understandable reporting, and integrations with existing tools.
When mapping this technology to SecTec portfolio vendors, it is important to consider not only the feature itself, but also deployment model, licensing, management level, supported platforms, and integration with adjacent areas. In a specific architecture, NDR may be a standalone platform, a capability, or part of a broader solution.
How To Assess The Technology
When selecting a solution, the most important assessment points are:
- which problem the solution covers and where its boundaries are
- whether it supports the organization's existing environment
- how it integrates with SIEM, SOAR, XDR, IAM, cloud, or ticketing
- what level of automation, reporting, and auditability it provides
- whether it reduces operational complexity or only adds another isolated console

Attack coverage and defensive context
MITRE ATT&CK® Enterprise version 19.1 is used as a reference model. The mapping is a SecTec expert interpretation and does not imply endorsement by MITRE.
Practical attack scenarios
- Credential theftAn adversary obtains passwords, tokens, sessions, or other authentication material and uses it to expand access.
- Lateral movement inside the networkAfter initial access, an adversary discovers systems, accounts, and services and moves toward higher-value assets.
- Malware and Command and ControlMalicious code executes, maintains access, and communicates with adversary infrastructure through common or covert channels.
- Attacks on OT and IoT environmentsAn adversary discovers industrial or connected devices, abuses remote access and network services, and threatens operational availability.
- Reconnaissance and attack surface mappingAn adversary collects information about people, systems, cloud services, and internet-facing infrastructure and searches for a viable initial-access path.
- SSRF – Server-Side Request ForgeryAn adversary causes a server or API to fetch an attacker-controlled address and reaches internal services, cloud metadata, or protected network targets.
- Shadow and zombie APIs without managed inventoryUnknown, forgotten, or outdated API versions remain reachable without current controls, ownership, documentation, and monitoring.
