More and more network traffic is encrypted as people and businesses try to keep their data private and secure as it travels through the Internet. By encrypting transmissions, sensitive information, such as a user's login ID for an online banking session, or perhaps a credit card number, is protected and kept out of the hands of potential hackers and criminal organizations. By 2019,...

Network visibility goals never change—you want to deploy the right combination of network taps, network packet brokers, and

Critical Enabler for Robust Network Visibility Over the last few years, network equipment manufacturers have been in the process of broadly adopting fan-out technology for data center networking to increase port density. In this blog, we will examine how port fan-out technology overall enables higher scalability and flexibility for next-generation data centers and, when specifically applied to Niagara Networks N2 network bypass and

How to Achieve Hybrid Network Visibility with a Central Controller In the first part of this mini blog series, we talked about the new reality for IT leaders—hybrid networks. Despite the all-or-nothing excitement in the early days of cloud computing, it’s clear that on-premises infrastructure isn’t going anywhere anytime soon. Rather, the key to network success is finding your perfect balance of on-premises, public cloud...

The more we rely on network-connected systems and services for mission-critical processes, the more important it is to design for network visibility. Vendors have been preaching the importance of network visibility for decades. While it’s important to have the right combination of network...

In contrast to the other components of enterprise networks, the wide-area network (WAN) stands out as the most demanding to administer because it often includes a variety of services and devices with most of those devices at unsupported sites. Management and upgrading is difficult; often remote access to WAN devices is only possible via the WAN itself, so resolving any major errors made during an upgrade may demand physical access to the device itself.

Distributed Denial of Services (DDoS) Overview Denial of service is a form of cyber-attack in which attackers overload computing or network resources with so much traffic that legitimate users are prevented from accessing to online services such as online banking and e-commerce. Enterprise websites are a preferred target since they provide the most engagement with an organization’s customers, partners, subscribers and followers.

How Visibility Can Make or Break a Hybrid Network The modern enterprise IT team faces a seemingly impossible task. More and more, IT leaders are under pressure to dramatically increase agility, maximize workforce productivity, eliminate any security threats, and address every compliance requirement—all while cutting costs. As business leaders accelerate digital transformation initiatives, there’s a fundamental misconception ...

There’s one glaring problem with modern security tools. Even if you’ve deployed next-gen firewalls (NGFW), intrusion prevention systems (IPS), data leakage prevention and more, they’re all useless without total visibility of network packets.
