FAQS
IT network analyst FAQs.
They monitor, evaluate, and optimise network performance — ensuring consistent uptime, flagging anomalies, and analysing bandwidth usage. They often feed insights into infrastructure planning and incident prevention strategies.
While administrators manage configuration and engineers build networks, analysts focus on monitoring and improvement. It’s more diagnostic than hands-on — identifying trends and weaknesses through data.
SolarWinds, Wireshark, Nagios, PRTG, and NetFlow analyzers are common. Analysts also use reporting dashboards and often contribute to incident response reviews and root cause documentation.
Large businesses with complex WANs or multi-site setups — such as retail chains, banks, or public sector networks. Anywhere performance data needs to be reviewed and acted on regularly.
Progression often leads to network engineer, infrastructure analyst, or security operations centre (SOC) analyst roles. Some also specialise in performance optimisation or vendor management.
