I have no idea if it will stay free or free to existing Agnitum customers or whether it will become a part of a suite, etc.
At the moment there is a proposed Outpost Security Suite Pro, which I'm personally against as suite bloatware. They are spending a lot of time on that suite when the outpost pro isn't Vista compatible and unlikely to be until the 2nd half of the year. I think they have their priorities completely wrong, but at least the stand alone Outpost Firewall Pro is to continue. It is these muddled actions that also and I think trying to get a slice of every pie would also make me wonder about Spam Terriers future.
