News From PaesslerDetecting Exploitation: How Network Monitoring Complements your Security StackRule #1: Always Assume Breach An important principle in cybersecurity is to use the ?assume breach? mentality, using the idea that an attacker has already infiltrated your system. This mindset helps minimize the blast radius of an attack, limit lateral movement around your network, and contain potential breaches before they escalate. What Does a Network Administrator Do? Roles, Skills & Career PathIt is hard to imagine a modern company without a stable Internet connection or without services on its local network. Behind this stable infrastructure is an employee who helps keep all systems running smoothly: the network administrator. But who is a network administrator, and why is it such an important role for modern companies? Virtual Infrastructure Monitoring: Surviving the Layer Cake of DoomHere's a fun drinking game for you: take a shot every time you discover a VM in your environment named "test-server," "idk-what-this-does," or "IMPORTANT-DO-NOT-DELETE" that for some reason is running a production workload nobody wants to touch anymore. OK, actually don't do that - you'll need to be sober when the inevitable happens and one of those mystery VMs goes down, taking an entire half of the company's operations with it. PRTG 25.4.114 is now available in the stable release channelWe've just released PRTG version 25.4.114 to the stable release channel. This version brings you important fixes for the Windows Updates Status (PowerShell) sensor and the VMware Datastore (SOAP) sensor, as well as new capabilities in the PRTG API v2. How to Solve Network Connectivity Problems (And Prevent Them)When you can't get online, it's more than just frustrating. It's a productivity killer. Network connectivity problems are more than an inconvenience. They can take your entire business offline. Time wasted staring at a blinking modem waiting to get online. When connectivity goes down, it's not just obvious how much time is wasted. You can't even easily research solutions. You find yourself jumping through troubleshooting loops trying to find out if the problem is your router, the ISP, or something else entirely. IT Monitoring Trends 2026: From Multi-Cloud Chaos to Unified VisibilityIn 2026, you face a perfect storm of multi-cloud complexity, IT/OT convergence, and tightening regulation. This article gives you a practical outlook on what will change in monitoring, how AI and security trends will shape your decisions, and where solutions like Paessler PRTG can help you turn visibility into advantage for sysadmins responsible for their company's IT infrastructure and Managed Service Providers (MSPs) alike. Proactive IT Support: How Real-Time Monitoring Reduces Downtime and Drives Business GrowthHow much does IT downtime really cost your organization? Most executives think it's just an annoying blip on the radar. But if you've ever been on the receiving end of a 3 AM call because the production server went down, you know better. Studies put the number at over $5,000 per minute for large organizations. Per minute. That's the cost of your CEO unable to access email, sales teams locked out of CRM systems, and customers abandoning shopping carts. Network Redundancy: The Safety Net When Everything Goes Wrong[Update] Ironically, as soon as this blog went live, Cloudflare went down! So I will use this opportunity to say... I told you so! Keep reading to find out why. Someone, at some point in time, (hopefully some kind of professional network engineer) designed your network. They drew a pretty picture with multicolored lines showing traffic flowing between a primary path and a secondary path. Oh, and this plan also had a budget and important management buy-in. Then they moved on to another company, country, or just a better job, and what you've been left with is a Frankenstein's monster of temporary-band-aid solutions to real problems that all became permanent circa 2015. Your so-called redundant paths? One goes down, and the other follows like some kind of tragic Romeo and Juliet situation - it's heartbreaking. Network Visibility: How to Eliminate Blind Spots in Your IT InfrastructureYou can't fix what you can't see. That's the fundamental problem every IT team is up against when trying to keep their network humming along. Right now, there's almost certainly a bandwidth bottleneck building up somewhere in your infrastructure. An unauthorized device plugging into the network. Encrypted traffic containing something it shouldn't. The question isn't whether these things are happening. They are. The question is whether you can actually see them when they do. How to Look at Network Traffic: Essential Tools and Methods for Real-Time AnalysisNetwork traffic monitoring is one of the most crucial tasks for any IT professional or sysadmin. Whether you?re troubleshooting performance issues, hunting for security vulnerabilities, or optimizing bandwidth usage, understanding how to effectively monitor network traffic can be the difference between a healthy network infrastructure and costly outages. Monitoring Basics: How to Check Network TrafficIt's always DNS. Unless it's not. Then it's the network. Or perhaps the firewall? Or wait, actually, according to Chris in accounting, it's CERTAINLY malware because his nephew 'knows computers'. Welcome to every network performance troubleshooting discussion ever because everyone is an expert and all you get to do is smile politely. PRTG multi-platform probe joining the Siemens Industrial Edge EcosystemWe are excited to announce a major step forward in OT monitoring: PRTG multi-platform probe is now available on the Siemens Industrial Edge Marketplace. This partnership bridges the gap between IT and OT environments. It gives customers better visibility and more direct control over their industrial operations. Network Segmentation: Dividing Your Network to Stop AttackersAn attacker has just deployed malware on your network via a compromised employee laptop. In a flat network, they scan your entire internal network, locate your database servers, and exfiltrate customer data in a matter of hours. With network segmentation in place, that same laptop ends up in a guest segment with no route to production systems. The breach gets contained before disaster. Observability vs Monitoring: Key Differences Every IT Team Should KnowYour digital transformation is only as good as the technology that supports it, which is why it's so important to maintain the system health and performance of your infrastructure. Do you have microservices or distributed systems to keep track of? Cloud-native apps, container workloads, Kubernetes environments, or multicloud systems? You need to see what's happening across your entire IT landscape, and the critical question is, how do you do that?
