Israeli security company Yoggie Security Systems expired quietly three months ago, but its products live on as lonely orphans in the inventories of a dozen websites that have yet to hear of its mortality.

That means, presumably, that people are still buying Yoggie's security dongles when they probably shouldn't be bothering. If you were considering becoming one of those people then read the formal explanation for its disappearance, the inability to find an investor, and think again.

It wouldn't be accurate to say that a Yoggie dongle is now totally useless as a security device, but it's the next worst thing, one that will never be updated and has no support.

For the history books, Yoggie's fundamental problem wasn't that it didn't work at all but that there are fundamentally cheaper and simpler ways to secure computers than adding a hardware dongle through which all traffic, including wireless, must be run. Designed to save CPU cycles by offloading security functions from the CPU, it actually ended up using them.

An interesting if desperate foray to turn the device into a security platform where embedded apps were developed on the open source basis failed. Nobody turned up.

So, the Yoggie was a case of an interesting solution to the wrong problem. A better and more recent solution is to use a very different kind of dongle - the USB stick - to launch virtualised browser sessions that secure certain kinds of online activity such as bank access and leave the rest to good old antivirus and a firewall.
