How do you control access to .NET applications?

Visual Guard automatically adds security features to your applications. Manage users, their access to your applications,and grant them authorizations (what users can do, see and modify). Visual Guard manages security independently from the code. You can add permissions at runtime without touching the code and avoid the development cycle: coding, testing, deployment... Permissions are immediately available!

Visual Guard provides a console to manage users, roles and authorizations. Non technical-persons can use it, which frees the technical team from daily management of security. Visual Guard also provides ready-to-use features to comply with reporting requirements like SOX: you can automatically produce reports about the permissions granted. Visual Guard secures Winforms, Webforms and Webservices. It supports AD and DB accounts to identify users.

Those of you who have made the switch to 2008 might want to take a look at what has been fixed, and if you’ve run in to any of these problems you should probably get this hot-fix. I don’t know about the rest of you, but I am glad this hot-fix gave me back the “View Code” context menu item.
