NGFW
NGFW belongs to the Network Security area. NGFW combines firewalling, application control, IPS, VPN, and other security functions in one network gateway. Modern NGFWs work with identity, applications, and threat context.
Acronym Glossary

- NGFW
- Next-Generation FirewallA firewall combining application control, IPS, VPN, user context, and security functions.
What This Technology Covers
NGFW combines firewalling, application control, IPS, VPN, and other security functions in one network gateway. Modern NGFWs work with identity, applications, and threat context.
Why It Matters
It is a key choice for perimeter protection, segmentation, branches, and hybrid cloud connectivity.
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
NGFW 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 It can complement an existing architecture, replace an outdated tool, improve visibility, or consolidate functions currently split across multiple products.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, NGFW 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, NGFW 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
- Public application or API abuseAn adversary exploits a vulnerable web application, API, client-side code, or software component for initial access and execution.
- 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.
- Ransomware and availability impactAn adversary encrypts or manipulates data, stops services, inhibits recovery, and creates operational impact.
- 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.
- Defense evasion and control impairmentAn adversary hides activity, removes evidence, disguises code, or weakens security tools, encryption, firewalls, and recovery mechanisms.
- DDoS and resource exhaustionAn adversary floods a network, application, API, or endpoint and exhausts capacity, connections, or compute resources to reduce service availability.
- API resource and cost exhaustionAn adversary abuses expensive API operations, large inputs, or paid services to exhaust CPU, memory, storage, connectivity, or financial limits.
- 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.
