Does your IT team have a clear view of your Cisco network's health and performance? Cisco routers, switches, firewalls, and wireless devices need regular monitoring to catch network issues before they affect users. Cisco network monitoring tools help you: However, not every tool supports Cisco technologies such as Meraki, IP SLA, ACI, and SD-WAN. In this guide, we compare 9 Cisco network monitoring tools based on their features, limitations, deployment options, and pricing.

Why would a domain with correct records, healthy name servers and a valid certificate stop resolving for part of the internet? Often it's DNSSEC. Your records are fine; the signatures behind them are not, and any resolver that checks signatures now refuses to answer. DNSSEC was designed to stop spoofing and cache poisoning, and it works. The catch is operational.

Why does an application that runs well in the data center slow down once one of its tiers moves to AWS or Azure? Often the servers are healthy and the cloud console shows no faults; the delay lives in the connection between them, where neither view reaches. That blind spot shows up in familiar ways: So these are design problems before they are operational ones.

Does your IT team know which applications, users, or devices are consuming the most network bandwidth? A video call freezes, file transfers slow down, or a network link becomes congested. Without traffic analysis, finding the source of the problem can take hours. Network analyzer software helps your IT team: However, tools differ in how they collect traffic data. Some analyze flow records, while others also inspect packets to provide more detail.

How many devices are on your network right now? The usual answer is “check the spreadsheet”, and nobody is quite sure which copy is current. That's awkward during an outage and worse during an audit, or on the day a vendor advisory asks which switches run a vulnerable firmware build. Network inventory management retires that spreadsheet. In its place, you get a record that changes when the devices do, with hardware, addresses, VLANs and every router and switch config in one place.

If your IT team struggles to track devices, software licenses, warranties, and contracts, managing assets can become difficult. IT asset lifecycle management software helps you track every asset from purchase to retirement. It gives your team a clear record of: However, tools differ in their discovery methods, lifecycle workflows, license tracking, deployment options, and pricing. In this guide, we compare 7 IT asset lifecycle management software tools based on their features, limitations, and pricing.

Think about Outlook, Salesforce or the shared drive your staff open each morning, and at least one of them probably runs in AWS, Azure or Google Cloud. That puts a good share of your traffic on a cloud network nobody on your team has ever seen. You still own a lot of that path (the VPN link, the route tables, the security groups), and it breaks in ways an office network doesn't.

Most network diagrams we come across land in one of two piles: the one drawn for an audit years ago and never opened since, and the one so crowded that finding the firewall takes squinting. The network diagram examples below sit between those piles, 8 diagrams IT teams actually use, sorted into physical, logical, and cloud or WAN. For the full build process behind one map, see our guide to the network topology diagram.
