When a program has a “free” edition, very often, it is just a demo without a time limit, offering only enough functionality to get you to buy the “real” version. Capsa 7 Free is not such a program; it’s a full-featured network traffic monitoring and reporting tool. The features you get for free, without a time limit or unceasing nags, are exceptional.

This high level overview is just the start of Capsa Free; you can drill down very deep to learn more about your network.

Capsa Free provides an ongoing look at everything that passes through a selected network adapter. (This is one of the few limitations of the Free version vs. the Professional and Enterprise versions; you can analyze only one adapter at a time. For most home or small business users, this will not be an issue.) It breaks the data down by protocol and IP address, the latter of which is very interesting from a home user perspective–a days’ casual surfing, captured and analyzed by Capsa, revealed I contacted computers in over a hundred different nations. You can also set it to store packets, with a variety of options for how many to store and how long to keep them. Later, you can rummage through them with Capsa, if you know what you’re looking for (or just want to peek under the hood and understand more about what happens between when you type an address in your browser and when you see a picture of a cat appear on your screen.)

For network administrators in small businesses, Capsa 7 Free is a potent tool with many analysis and testing abilities. With it, you can see what’s happening on your network, whether you want to monitor usage or determine if a connectivity problem really is on your end, You can hand-code packets and then send them to an adapter, in order to see what happens. The ability to set alarms if particular traffic patterns occur can help you see an attack coming and head it off, and there are tutorials on-line to help you do just that.

Capsa Free is a tool for professionals and enthusiasts. A casual home user will not find much use in Capsa Free, though, being free, it doesn’t hurt to check it out. Using it requires either a good knowledge of internet protocols and low level functionality, or a strong desire to learn such things. If most or all of your traffic routes through a single network adapter, you may never see a need to upgrade to the Professional edition, which starts at $549.00.

If you run any type of network infrastructure there will come a time you need a low-level packet sniffer to work out just what is going on. Colasoft’s Capsa product challenges the myth these tools must be hard to use.

Have you ever had users ask why is the network so slow? Chances are high any IT professional will have looked into network related faults but found it difficult to get a handle on just what is going on because Ethernet is so, well, ethereal.

Here is where a network analyzer comes in handy. It will sniff the raw packets of data flying about as they happen and give you meaningful information to make intelligent determinations.

Previously I have talked about the tremendous open source product WireShark but WireShark isn’t for everyone. For one, the Windows port requires GTK+ and Glib to be installed which some Windows administrators aren’t keen to do. For another, although it is less arcane and cryptic than a command-line tool like tcpdump it’s still not user-friendly enough for many.

Here is where Colasoft’s Capsa product comes in. As you might guess, it is a deep low-level network protocol analyzer and its purpose is to give you the low-down on just what is happening on your network.

Where it stands out from the competition is its brilliant ease of use. Capsa adopts the same ribbon style interface as seen in Microsoft Office 2007 and it is a snap to navigate between tabs and check out the options and power available.

When it comes to network analysis so much is going on that it’s a must to separate out the chatter from the data that matters. Capsa makes it a cinch to hone in on what you want with easy to use filters and rules.

Capsa also has a concept of projects, meaning you can set global filters and rules to always apply but also make specific filters and rules for individual projects, letting you switch between these as needed.

Capsa displays intuitive options and is a genuine pleasure to use. I do not believe I’ve seen a more straightforward or elegant network analysis tool with the majority requiring expert knowledge to get any meaningful results.

Capsa is a commercial product so it does carry a price tag beginning at $US 549 for one license without maintenance but if your job requires you to troubleshoot network faults then the software will pay for itself.
As well as the commercial support Colasoft provide an extensive and helpful FAQ. A free trail of Capsa is avaliable here.
