PortSentinel

PortSentinel specializes in monitoring network host availability and service port functionality across your infrastructure. It continuously checks devices with IP addresses—including workstations, servers, and routers—using TCP, UDP, HTTP, and ICMP protocols. The system tests service efficiency by attempting connections to TCP ports running essential services such as web servers, mail servers, and domain controllers. Immediate failure notifications ensure administrators can quickly address issues, minimizing downtime and maintaining optimal network performance.
