About Internet Access Monitor

A modern, independent guide to monitoring how a network really uses the internet.

Internet Access Monitor helps the people who run networks answer plain questions: what's using our bandwidth, which sites and cloud apps people actually reach, and who's consuming what — cleanly, and without crossing privacy lines. It's a practical 2026 reference for IT admins, sysadmins and network engineers, built around real tools and real data sources, not a brochure and not a museum.

The name is carried forward. In the 2000s, Internet Access Monitor from Red Line Software was a pioneering tool that turned proxy-server logs into readable per-user internet-usage reports — no agents, no complexity. We're independent and unaffiliated with that company; we simply admire what it did, and we carry the craft forward with today's tools. There's a short Legacy page if you'd like the real story.

What you'll find here

• Fundamentals — what usage monitoring tells you, and the four data sources behind it.
• Bandwidth & Traffic — finding hogs, reading NetFlow, top talkers and saturation.
• Web & App Usage — which sites and cloud apps get used, DNS visibility, email and print.
• Choosing & Deploying — what matters, self-host vs cloud, alternatives, alerting.
• Legacy — one factual page on where the name comes from.
