Does the iPad have any security software?

I'm looking for online security (tablet security) for my iPad both while traveling and otherwise. I have also started to use my iPad for banking, so the extra security and internet speed is a necessity.

If you're an active iPad user, whether personally or in your corporate/enterprise environment, then please let me know the monthly cost of security subscription. Thanks in advance.

I'm looking for a self-configuring iPad security software than works with Wi-Fi/3G models and is compatible with any data, wireless or cellular provider in the state.

I need to make my iPad more secure on New Zealand networks (both WiFi and 3G) while travelling, banking as well as public and private use. What do I install and where can I get it?

I'm specially looking for an online store from where I can download and install such a software. It's got to work in Sydney, of course, but it would be useful if I can use it anywhere in Australia as well. Is there something that fits the description...

What do you use for wireless iPad security in public places (either 3G or wi-fi)?

I live in Adelaide, Australia (same place I buy my Apple iPad and accessories from) and want to know if there's an app or VPN-based security system that will automatically make my internet browsing private and secure. Where can I buy such an app?

...for folder locking; or at least if it is possible to create an encrypted partition on the iPad. I need it for txt files, I' ve heard that the kind of file matters. Thx again to all who will answer again, since my first question was incomplete
