Paessler PRTG

Your infrastructure is complex. Your monitoring tool shouldn't be. Paessler PRTG delivers mission-critical visibility across IT and OT environments, deploying in minutes, not months. Whether you're managing servers, switches, virtual machines, cloud services, or industrial systems, PRTG monitors everything from a single platform, so your team always knows what's running, what's struggling, and what needs attention, before users do. Fast to deploy. Easy to run. Auto-discovery finds devices on your network automatically, and 300+ pre-configured sensors cover the most common infrastructure components out of the box. Support for all major protocols (SNMP, WMI, REST APIs, SSH, NetFlow, and more) means PRTG fits into your existing environment without forcing changes to it. Built for lean teams under real pressure. Customizable dashboards give instant visibility across your entire landscape. Flexible alerting (via email, SMS, push notification, or third-party integrations) ensures the right people are notified the moment something goes wrong. Historical trend data helps you spot patterns and plan ahead, not just react. Scales on your terms. From a single site to distributed multi-location environments, PRTG grows with your organization. Available as an on-premises installation or a hosted solution, it adapts to your infrastructure and your IT policies, no rip-and-replace required. Trusted by more than 500,000 users across 190+ countries since 1997, Paessler PRTG is the monitoring standard for IT professionals who need results, not complexity.
