IT Skills Shortage: How to Do More with the Team You Already Have
The IT skills shortage is not a future problem. It is already showing up in every helpdesk ticket that waits an extra day and every project that gets pushed back a quarter. The U.S. Bureau of Labor Statistics projects that computer and information technology occupations will grow much faster than average through 2034, with tens of thousands of open roles appearing every year that nobody is lining up to fill. For IT administrators, that gap rarely shows up as a headline. It shows up as one more alert at 2 a.m. that only you can answer, because there is nobody else scheduled to answer it.
Bridging IT and OT in the Energy Sector: Making Substation Monitoring Actually Work
Somewhere between a wind farm substation and the utility's central control room sits a patchwork of equipment nobody quite planned for. Programmable logic controllers running firmware from a decade ago. Remote terminal units wired into protection relays older than the company's IT department. A SCADA system that, until fairly recently, nobody outside the operations team had ever logged into. That patchwork is now part of the energy sector's information technology and operational technology landscape whether anyone designed it that way or not - and it's exactly the kind of environment where IT/OT convergence gets tested for real, not on a slide.
20 New and Improved Sensors: PRTG 26.3.122 is Here
We just released PRTG version 26.3.122 to the stable release channel, and it brings a full package: seven brand new sensors, ten sensors that graduate from BETA, three experimental additions, and a range of security and server improvements
Hospital IT Security: Closing the Gap Between Medical Devices and Cyber Defense
Hospital corridors run on more than doctors and nurses these days. Behind every patient monitor, every infusion pump, every radiology workstation sits a network connection, and that connection has quietly become one of the favorite entry points for attackers. Hospital IT security used to be a back-office concern. Not anymore. It now touches patient safety and patient care directly, which is exactly why cyberattacks against healthcare facilities keep making headlines.
Shadow IT Risks: Uncovering Hidden Security Gaps in Your Network
Shadow IT risks are quietly reshaping the job of every IT administrator, whether they have noticed it yet or not. Shadow IT itself is nothing new: it is any hardware, software, or cloud-based services running on company systems without the knowledge or approval of the IT department. What has changed is the scale of it.
NIS2 Compliance in Practice: The Role of Infrastructure Monitoring
The NIS2 directive is no longer a project on the horizon. It is enforced EU law, and national law in most member states now reflects its requirements for cybersecurity risk management, incident reporting, and business continuity. Compared with its predecessor, NIS1, the scope has grown substantially: many more organizations across critical sectors and important entities now fall under the regulation, from energy and transport to healthcare, banking, and digital infrastructure.
Cloud Cost Optimization: Why IT Admins Can't Fix What They Can't See
What does the cloud actually cost this month? Ask finance, ask the DevOps lead, ask the admin who provisioned half the instances two years ago – chances are good all three give a different number. That gap is not a rounding error. It is, according to Flexera's 2026 State of the Cloud Report, roughly 29 percent of total cloud spend disappearing into overprovisioned resources, idle compute, and services nobody remembers switching on.
Alert Fatigue in IT: Why Your Team Stops Listening (And How to Fix It)
Quick question. When was the last time anyone on the team actually read a monitoring alert, word for word, before dismissing it? Not skimmed. Read. Take a second with that one. If the honest answer is "can't remember," alert fatigue has already moved in. It doesn't show up with some dramatic outage or a red banner screaming for attention. It's quieter than that, and slower. Hundreds of small, forgettable pings, week after week, and then one random Tuesday someone realizes nobody on the team trusts the alert system anymore. They just click things away. Swipe, dismiss, next.
AI Infrastructure Monitoring: Why Your AI Stack Is Only as Strong as What Runs Underneath
Funny thing about IT lately. Everyone's talking about machine learning models, training pipelines, whatever flashy thing some company just shipped. Almost nobody talks about the boring stuff underneath. The servers. The network. That storage volume slowly filling up while nobody's watching. That part gets ignored right up until it breaks, and then it's suddenly the only thing anyone cares about.
The Right Support at the Right Time: Introducing PRTG Premium Support
Every IT environment is different. Some teams are small, agile, and handle most things in-house. Others run large, distributed infrastructures where every minute of downtime has real consequences. Our new PRTG support model is built around exactly that reality.
Three New Sensors, Smarter Monitoring: Prtg 26.2.120 is Here
We just released PRTG version 26.2.120 to the stable release channel, and it comes with a lot to talk about. Three new sensors graduate from BETA or join the lineup for the first time, a brand-new AI chatbot lands in the New UI, and a range of security hardening measures, server improvements, and sensor fixes round out this release.
6 DevOps Automation and Integration Best Practices
There's a gap that lives in almost every DevOps team, and it goes something like this: you've automated the pipeline, the deployments are running, the CI/CD is humming - and then something breaks in production and nobody knew until a user filed a ticket.
Proxmox VE Monitoring Done Right: How PRTG Keeps Your VMs, Containers, and Cluster in Check
If you've made the switch from VMware to Proxmox VE - or you're seriously considering it - you already know that monitoring can't be an afterthought. The Broadcom acquisition changed the economics of VMware practically overnight, and for many organizations, Proxmox VE became the obvious answer: open source, proven in production, no licensing surprises. But switching hypervisors is one thing. Making sure your new environment is properly monitored is another.
Never Miss a Patch Again: How to Monitor Windows Updates Across Your Entire Infrastructure
Every IT admin has been there. A critical vulnerability drops, and suddenly you're scrambling to figure out which machines are patched and which aren't. In a small environment, that's annoying. In a network with hundreds of endpoints across multiple sites? It's a genuine nightmare. And here's the thing — without proper Windows update monitoring, just one unpatched Windows server can become the door that attackers walk right through.
Windows Server Monitoring Best Practices: How to Keep Your Server Performance Under Control
Your Windows server goes down at 2 a.m. on a Friday. Nobody noticed the warning signs - disk space had been creeping up for days, CPU usage spiked every evening around 6 p.m., and the event logs were practically screaming for attention. The on-call admin gets woken up. The helpdesk starts filling with tickets. And somewhere, a manager is asking why nobody saw this coming.
