VPNs are a staple of corporate life nowadays. They create a secure connection from your computer to your company's computers using a 'Virtual Private Network.' This allows you to access company documents via public networks in a secure fashion.
Cisco is a big player in the VPN market, and luckily for us OS X users there is a Mac client that allows connections from Macs to Cisco VPN appliances. Sadly, it sucks. The interface isn't Mac like, and while it works it doesn't offer up any nice features like Keychain integration or automatic reconnects. Enter Shimo, from nexUmoja. This little program offers up an alternative UI to the Cisco client that adds a number of features including Keychain integration, Growl notifications, and auto reconnecting.
All of this is great and as a user of Cicso's VPN client you would think I would use this without hesitation. Sadly, the whole point of VPNs is to make your communications more secure, and I simply don't trust a third party app sitting between my encrypted data and the Cisco VPN appliance. That's just me though, I'm slightly paranoid.
