To start, I am a servicemember and a DoD employee, so discovering this distro was a godsend. Why don't they tell DoD employees that this exists, and encourage us to use it? Who knows. Normally, if I wanted to access my DoD email or any .mil sites outside of work, I'd either have to check out a work computer and have our IT staff configure a VPN on it (and request VPN access, which is a hundred-step process from hell, as with anything in the government), and then lug that around with me in addition to my regular laptop.
Thanks to this product, I can just carry around my regular laptop. I boot this in a VM on the laptop itself, and am able to do everything I can do on our secure work computers, on my personal laptop, in a secure and contained environment.
My main gripes about this are that you can't install additional applications to it - but hey, it has pretty much everything you'd normally need right out of the box.
If the DoD wants an ideal next step for where to take this, they should build a package manager for it so that one can keep their TENS image up to date, update the applications in it, and install new software (or, the DoD could just use an existing package manager while hosting a repo with up-to-date packages themselves).
I use TENS on a netbook with dual core Atom 1.6 GHz processors and 2 GB RAM. I run it off a USB stick and plug in just when I need it, eg for secure tasks like banking. Although settings cannot be saved in TENS, it is easy to save Firefox browser add-ons, eg firewall, ad block, file downloader, etc via Mozilla Synch facility built in to browser.
You can save bookmarks on a separate memory stick and install into Firefox each time via the 'Bookmarks' tab.
In my opinion, TENS would be better if there were a choice to use the Chromium browser instead of Firefox and make use of all the Chrome apps in the Google Store. Then it would really fly!
My wif fi works well and is very sensitive. If the previous commentator has a problem, try reloading TENS from the source on to a bootable USB and start again..
Useful, secure enough and more versatile than you might think with its range of utilities and other software.
