  • Monitoring and analyzing network security devices

    Monitoring and analyzing network security devices

    Network device monitoring is the process of managing and analyzing hardware devices within a network. This includes routers, switches, firewalls, and servers. The goal is to ensure these devices are operating optimally, by tracking their performance, availability, and security. They capture and analyze traffic, oversee hardware, and provide instant visibility into bandwidth usage, latency, packet loss, and other key metrics. This means, their scope has expanded beyond the internal network to include the cloud and more. Here is our list of the best.
