What is the network edge?
The network edge is defined as where a device or local area network (LAN) connects to the Internet, creating boundaries between IT domains or an interface between two network segments, including the Internet, public or private cloud, or co-lo, or WAN. It is called the "edge" because this is the entry point to the network where devices themselves are communicating with the Internet. These domain points may be owned by either the same or different organizations.
Security at the network edge is vitally important to ensure the entire network is protected from attack or intrusion.
What is a network perimeter?
A network perimeter is the physical boundary between a business’s private, locally managed network, which in some cases is an Intranet, and the publicly accessible Internet. The network perimeter remains under the control of the organization. Devices that operate at the perimeter are Border Routers, providing access across the border.
NETSCOUT's Arbor Edge Defense (AED) is an inline security appliance deployed at the network perimeter (i.e. between the internet router and network firewall).
What is the difference between network edge and perimeter?
As previously defined, the network edge is the precise point where devices connect to the Internet, while the network perimeter is the actual boundary between private and public networks.
What is network perimeter defense?
There are many ways of protecting a network. One of those ways is a perimeter defense using a firewall to deflect and prevent external attacks. Perimeter defense is typically deployed as part of a more comprehensive protection suite. By using multiple layers of security, businesses can more effectively protect their network and vital data.

What is nGenius Enterprise Performance Management?
Today’s applications are increasingly moving to the edge in order to facilitate faster performance and a better user experience. As a result, performance monitoring is now being deployed to begin providing insights into how apps are functioning. As the edge has become more complex, more sophisticated monitoring is required.
nGenius Enterprise Performance Management provides the visibility needed to uncover problems with remote applications and microservices. Armed with such insights, IT professionals can avoid having to go on-site to investigate issues and instead prioritize those problems that require immediate attention to ensure application performance is optimal.
NETSCOUT's nGenius Enterprise Performance Management Solution brings visibility throughout ever-evolving, multi-cloud environments to solve performance issues affecting digital services across technology and organizational boundaries. nGenius Enterprise Performance Management assures high-quality end-user experience in any network, location, or service for any user, regardless of where they perform their jobs.
What is edge computing?
Edge computing is the act of delivering computing power as close as possible to the source of data in order to dramatically reduce latency and bandwidth use. Put another way, edge computing involves running fewer processes in the cloud where they must traverse a greater distance over the network, and having the processing done locally. Examples of edge computing might be having processing done on a user’s own computer, through an Internet of Things (IoT) device, or an edge server. By moving processing to the network edge, the distance communication has to travel between a client and server is dramatically minimized, cutting down on latency and reducing bandwidth consumption.
Vital services that require edge computing might include autonomous vehicles, smart cities, manufacturing processes and healthcare systems, just to name a few.

NetSecOps: Aligning Networking and Security Teams to Ensure Digital Transformation
Network and security teams aren’t natural partners. Their core missions are fundamentally opposed. Still, network teams recognize the importance of building security into everything they do, and they know that the security team has deep expertise that can help. With the right leadership, these partnerships can flourish.
