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.

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...

The beating heart of the healthcare sector is under increased threats, and no amount of antibiotics can protect the proverbial patient. In this case, we’re referring to the vital networks healthcare systems and providers rely on to share data and treat patients. Today, the entire industry faces an unprecedented array...

As companies increasingly rely on mission-critical applications and services across remote sites, observability throughout expanded networks to troubleshoot problems is more important than ever. There is no doubt that reducing outage risk and application performance degradation is vital to any business, but network...

Geopolitical conflict continues to drive up the number of distributed denial-of-service (DDoS) attacks, with spikes of up to 1,900 percent in certain areas correlating with political events. Artificial intelligence/machine learning (Al/ML), automation, and the abuse of enterprise-grade infrastructure are making attacks...

A major retailer has just suffered a massive data breach. Customer credit card information is circulating on the dark web, fraudulent transactions are skyrocketing, and consumer trust is rapidly eroding. The attack was stealthy, persistent, and devastating. But how did it happen? To fully understand, we must retrace...

The explosion of digital data, along with the growing adoption of artificial intelligence (AI)-powered applications, has created exciting opportunities for businesses in nearly every sector. At the same time, there is growing awareness of the high energy consumption of these technologies, prompting businesses to search...

Digital resilience is not a response plan. It’s a readiness posture. Too often, business continuity strategies are activated only after disruptions occur. But by then, the damage has already begun. Systems are degrading. Customers are impacted. Stakeholders are asking questions. The real work of resilience happens...

Recent announcements by major North American mobile service providers are once again putting carrier aggregation in the spotlight.
