How Network Observability Can Help Mitigate Shadow AI Risks
By Eileen Haggerty, Area Vice President, Product & Solutions Marketing, at NETSCOUT For years, IT and security leaders have been locked in a high-stakes game of whack-a-mole with Shadow IT. It began with the bring-your-own-device (BYOD) movement, driven by employees who bypassed corporate policy to use the tools that made them the most productive. Today, that same relentless pursuit of efficiency has ushered in a new, far more complex challenge: unapproved AI.
Ensuring colocation success by eliminating network observability blind spots (Reader Forum)
1 As enterprises shift workloads into colocation facilities, visibility gaps across shared infrastructure can undermine performance and resilience. End-to-end network observability, including packet-level inspection, helps IT teams identify faults faster, reduce downtime, and maintain reliable digital services. The global colocation market is expanding rapidly, driven by explosive data generation, the limits of legacy IT infrastructure, and the demand for lower latency.

Op-Ed: Shortening transit outages with network observability
The morning rush hour on Friday, May 9, became a commuter’s nightmare in San Francisco as trains across Bay Area Rapid Transit (BART) lines came to a halt. The cause wasn’t an engine problem or a broken switch, but a faulty network component that failed to restart after a power outage. This resulted in intermittent visibility loss, where engineers could not see or communicate with the track circuits and train positions, leading to trains being held for nearly seven hours. The issue isn’t a one-off.
Overcoming IT Challenges in the Transition to Smart Grids
As energy companies transform digitally to meet customer needs, including providing greater energy usage transparency and real-time updates on outages, they are increasingly adopting new technologies. For example, many utility providers have been deploying smart meters to digitize infrastructure and enable real-time data transfers to data centers, with installed smart meters expected to exceed 1.75 billion by 2030.

Using Network Data to Improve the Performance & Security of Clinical Apps
From diagnosis to prescription, each facet of healthcare delivery hinges on the reliability of digital infrastructure in assuring the patient-care experience. Technical issues can impact diagnostic tests, disrupt scheduling, impair the delivery of prescription services, damage campus-wide communications, and ultimately, harm the patient-care experience.
Reducing remote site downtime through better network monitoring
Organizations with remote sites come in many forms, including distribution centers, warehouses, and factories. As companies embrace digital transformation, these often-massive remote sites rely on always-on application connectivity for seamless communication, collaboration, operations, and productivity. But when these systems fail, even for just a few critical minutes, these events can significantly delay production and distribution.
3 Steps for Better Troubleshooting Multivendor UCC Services
Use packet-monitoring strategy, third-party data to set baselines, more quickly resolve performance issues. Since the pandemic, large companies and organizations have increasingly relied on unified communications-as-a-service (UCaaS) platforms to keep their employees connected and productive. However, many have found that increased use of UCaaS or UCC services has also led to increased technical challenges, even several years later.
IT Skills Shortage To Blame for Recent High-Profile Failures?
It happened again. A major US airline suffered an IT problem that led to flight delays and cancellations. Such disruptions have become almost routine in the airline industry following multiple high-profile technology failures severe enough to ground flights over the last year. Yet the airline industry is not the only one to endure significant, headline-grabbing technology issues lately.
Simplifying Complex Fabrics with Open Source Based Solutions
While modern applications and workloads migrate from the data center out to the edge, the complexity of the supporting network infrastructure has been increasing exponentially. The proliferation of edge devices creates a litany of management silos and security headaches for network administrators, as legacy network solutions often struggle to provide the flexibility and innovation to support new initiatives, much less drive added value.
Why Is Custom Application Monitoring So Challenging?
Businesses are increasingly turning to purpose-built, custom applications to manage mission-critical processes. In fact, the average enterprise-level organization now has more than 460 custom applications to manage, according to the Cloud Security Alliance. Of course, there are many advantages to deploying custom applications, including ensuring adherence to precise specifications and allowing for greater control over processes that enable differentiation in the marketplace.
