Paessler

Paessler develops PRTG monitoring software for organizations that need continuous visibility into networks, servers, applications and infrastructure. While PRTG is primarily an observability and infrastructure monitoring platform, its security monitoring capabilities make it useful for identifying conditions that can indicate security problems. Teams can monitor firewalls, open ports, network traffic, Windows update status, antivirus availability and unusual activity from a centralized dashboard. PRTG uses sensors and protocols such as SNMP, NetFlow, IPFIX and packet analysis to provide operational context and generate alerts when monitored values deviate from expected conditions. This can help IT and security teams spot infrastructure weaknesses, availability problems and suspicious traffic patterns earlier. The platform is particularly relevant to enterprises, MSPs, schools, manufacturers and distributed organizations that need one monitoring layer across mixed environments. Its role is complementary to dedicated prevention and detection tools, providing the operational visibility needed to understand whether security controls and network services are functioning correctly.
