For all my Small Business friends:
Secunia, one of the big names in Patch Management (software that makes sure your computer is up to date) has just launched a cloud based service for small businesses with fewer than 50 PCs.
Secuina Personal Software Inspector (PSI) has always been free, but only for personal use. (and I highly recommend everyone install it as one of those must have bits of free software)
Corporate Software Inspector (CSI), thier main product line, has always been just out of reach for a lot of small businesses both from a price point and because it requires you to install and maintain a server for it. They recognized this limitation and put together this new Small Business solution.
Read about it here: http://www.net-security.org/secworld.php?id=14476
Sign up for the free trial here: http://secunia.com/products/smb/smallbusiness/
After the beta ends the first 5 machines will still be free and additional machines less than $5/month each.
I have been a user of PSI on my home computers for years and couldn't be happier. Now with this I have something to recommend that can protect small business machines as well.
