Firewalls are important network devices for security and other applications. They help filter traffic based on specific criteria to prevent illegitimate users from accessing the network. They are not, however, designed specifically for distributed denial-of-service (DDoS) protection. Many networks suffer from...

Zero-day threats are among the biggest risks in cybersecurity. They occur when a vulnerability—in this case meaning a security flaw or weak point in software or hardware that is unknown to the vendor or developers—is exploited to gain access. They are named as such because the vendor or developer has zero days to fix...

As part of a recent survey conducted by Mobile World Live, communications service providers (CSPs) were asked to weigh in on the state of artificial intelligence (AI) innovation and the challenges they face when deploying AI for IT operations (AIOps) in the network. Their responses, published in a 34-page report, offer...

There is no doubt that where people perform their jobs has received a great deal of attention over the last five years. Certainly, the focus initially was driven by the COVID pandemic and the safety necessary for employees and customers during this challenging period. Among the many adjustments of the time was to...

Enterprise Management Associates (EMA) has published its 2025 “ Enterprise Strategies for Hybrid, Multi-Cloud Networks” report highlighting the challenges facing enterprises as they design, build, and operate hybrid, multi-cloud networks. The study reveals details, trends, and conclusions about the status and use of...

Reducing energy waste is an operations principle for NETSCOUT. Lean operations support both cost savings and companywide sustainability goals. As discussed in our previous blog on sustainability, NETSCOUT has made significant progress in reducing the amount of energy consumed by its InfiniStream network monitoring...

There are about 18 billion Internet of Things (IoT) devices in use today. For context, there are “only” 8 billion people in the world. These IoT devices, from industrial scanners to retail sensors, are embedded in daily operations, handling tasks that were once manual, siloed, or slow to scale. As more industries rely...

Communications service providers (CSPs) need to continuously evaluate network performance 24/7 to assure service and end users’ quality of experience. This blog reports details from a Fierce Network interview with Bruce Kelley, senior vice president and chief technology officer at NETSCOUT, about the importance of...

Cybersecurity isn’t a game of cat and mouse. It’s a game of chess—one where the opponent is always thinking five moves ahead. Every organization wants to believe it has a strong defense, but attackers know better. They exploit blind spots, hide in encrypted traffic, and move undetected through networks. The problem isn...

Distributed denial-of-service (DDoS) attacks are evolving. According to the NETSCOUT DDoS Threat Intelligence Report, there is a decline in volumetric reflection/amplification attacks, but a rise in direct path dynamic multivector attacks that evolve to evade existing defenses. Adversaries are leveraging artificial...

As networks evolve toward higher performance and efficiency, AI is rapidly becoming a critical tool to support and enable this transformation across the end-to-end infrastructure, including the RAN. With growing network complexity due to technological advances, a more open vendor ecosystem, increased traffic volume...

As digital transformation accelerates and AI/ML adoption expands, organizations increasingly depend on actionable metadata to improve service assurance, observability, and cybersecurity. AIOps, SecOps, NetOps, and DevOps teams rely on high-quality, real-time data to train AI models that reduce mean time to resolution...

Businesses today are awash in workflows. As those workflows move to multiple clouds and the traditional corporate network perimeter begins to fade, enterprise IT professionals are finding it increasingly difficult to achieve complete control and visibility of data flows and the network traffic they bring in. The simple...

You don’t have to look too hard to see that the world is craving more connectivity and higher speeds. In fact, as the average number of people in a household continues to decline, the number of devices per household continues to rise. This trend is evident in a recent report that found “the total amount of fixed...

When we think about cybersecurity, most of us picture alarms going off, software scanning for viruses, and firewalls keeping the bad guys out. Detection and response are the heavy lifters in any modern security strategy, and rightfully so. They help us spot threats, shut them down quickly, and get back to business. But...

Digital tools such as mobile apps, quoting engines, and telematics are now table stakes in insurance. But behind every digital interaction lies a less visible challenge: technology that doesn’t always work as expected—and isn’t attended to until it impacts policyholders. Could gaps in network observability be silently...

Distributed denial-of-service (DDoS) attacks come in many shapes and sizes, as do the myths surrounding them. These myths can center on motivations, DDoS attack vectors and techniques, mitigation strategies, and more. DDoS myths are also sometimes more dangerous than the attacks themselves because the misconceptions...

Patients go to the facility where the doctor or treatment care they need is located. It might be a hospital, a medical building, an urgent care facility, or a clinic. Regardless of location, the expectation has always been a quality patient care experience: The medical professional they are dealing with will be able to...

Splunk has a great commercial titled No more “I don’t knows.” The commercial depicts an organization struggling to determine why its business-critical application is down. Question: Who’s working on the problem - IT, Engineering, Security? Answer: I don’t know. Question: Is it the network, the application, a cyber...

What did 109,000 people gathering in Barcelona, Spain, during the first week of March have in common? They all attended the Mobile World Congress (MWC). Many of them could be found at NETSCOUT’s impressive booth in Hall 2 throughout the four-day event. Attendees had the opportunity to learn first-hand about NETSCOUT’s...
