NetBarrier provides its “four-level line of defense” as a optimal security so that you can use the internet safely without leaving yourself vulnerable to any type of attacks.

The four-level line defense is as listed below

NetBarrier 2.1 has a few new features. Whether or not if this will make it harder for the average user to figure out now is a different story. As everyone has probably noticed that has used a previous version of NetBarrier is the difference in the interface, now carrying the infamous OS-X Aqua look.

My favorite new feature would be the choice on part of the user to set what you would like to do with an intruder before it actually happens so that you don’t have to be directly in front of the computer to stop him/her. If you liked the feature previously where it popped up a small window to ask you for how long you wanted the person to be off your network, don’t worry it is still there. There is also a new little feature if you didn’t like the alert sound that NetBarrier 2.0 came with you can change that to another alert sound that is on your computer. Another new key feature would be the filter to filter out all your personal information such as your credit card numbers and your passwords. We all shop online at times and we all worry that our information is somehow leaking.


Another great feature is the NetBarrier control strip. From your control strip you can quickly toggle settings to allow or reject type of connections. With the graphical user interface as seen above you can monitor the amount of incoming and outgoing traffic!

Now the data is filtered as it is going out of your network to wherever you may be putting your sensitive information. Same thing applies for your passwords whether it would be you logging into a website to check your email (ie:hotmail) or logging into a server of any type on the internet.

Another feature would be the Privacy features which hides what websites you visited last which comes in handy especially in a work environment where you share your computer with your co-workers. Also hides browser and platform information for websites that you browse onto that collect information about their surfers. Blocking spam from websites and advertisement banners are also good features as well as helping you control cookies.

One other feature I saw stuck out to us at, the ‘modem lock’ feature. This function will lock your modem so it will not be functional. Excellent for laptops or desktops you want to add a extra bit of security to. If your not using your modem then why have it open for connections, you never know who will be around your machines.

For a long time the macintosh was forgotten and most of the software companies stopped researching for the macintosh. Intego does a great job at pleasing their customers and always know what the macintosh users look for which are privacy and security.
