NxFilter
A professional DNS-based web filter for your network

NxFilter is a powerful Java-based web filter which controls access to web sites based on their domain names. It's also possible to limit access by user and time, and one NxFilter installation can protect your entire network.

You'll first need to install and configure the program, of course, and that can take a little effort. NxFilter isn't for network beginners, it won't fully set up everything itself, and even the web tutorial doesn't walk you through every detail. It's still not difficult - if you know how to configure your system to use a custom DNS server then you won't have much trouble - but you will have a little work to do.

Get NxFilter running on one PC, though, and it brings benefits right away, blocking known phishing sites and using packet inspection to detect some malware. A browser-based console displays stats on web traffic, blocked domains and more, as well as logging every site you've accessed.

If you need more control, it's possible to create NxFilter policies which block sites by category (75 in total), or only allow access to particular site categories - or all internet access - for a certain amount of time a day. These policies can be applied to individual network users, or groups of users. And you're even able to assign policies based on a time range, so for example an office might have a very loose policy at lunchtime, but something much more restrictive for the rest of the day.

This is just the start. If the default site blocking isn't enough, NxFilter supports adding domains manually, or grabbing the blacklist from www.urlblacklist.com. You get a stack of configuration options, there's even support for authenticating users via LDAP and Active Directory (as well as password and IP address), all while delivering great performance (the developer claims NxFilter can handle "several thousands of users easily").

v2.7.5 brings (Version History):
    - 'no_share_session' option for cfg.properties added.
    - 'Max domain length check' on policy bypassed at default.
    - 'Block covert channel' on policy is off at default.
    - 'Block mailer worm' on policy is off at default.
    - 'Block DNS rebinding' on policy is off at default.
 

Verdict:

NxFilter is an enterprise-level web filter, and setting it up needs some network experience, and a little time. But if you can manage a PC network then you shouldn't have much trouble, and what you'll get for your efforts is one of the most capable and configurable free web filters around.

WhatsApp Messenger 2.12.1

Free Full Commercial Software

WhatsApp Messenger is the world's most popular instant messaging app for smartphones.

You can use it to send and receive text and voice messages, photos, videos, even call your friends in other countries, and because it uses your phone's internet connection it might not cost you anything at all (depending on whether you'll pay data charges).

It's easy to set up and use. There's no need to create and remember new account names or pins because it works with your phone number, and uses your regular address book to find and connect you with friends who use WhatsApp already.

You can talk one-to-one or in group chats, and because you're always logged in there's no way to miss messages. Even if your phone is turned off, WhatsApp will save your messages and display them as soon as you're back online.

There's plenty more (location sharing, contact exchange, message broadcasting) and the app is free for a year, currently $0.99/ year afterwards.

Version 2.12.1 brings:
 - WhatsApp Calling: Call your friends and family using WhatsApp for free, even if they’re in another country. WhatsApp calls use your phone’s Internet connection rather than your cellular plan’s voice minutes. Data charges may apply.
