Free Advice:
We have made our pricing accessible. But we understand some young businesses running on a very short budget would need to implement some level of security to their systems without expense. That is possible. Windows operating systems from XP SP2 and up provide thru GPO or by the deployment of the following registry key write protection for USB storage devices.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies
WriteProtect dword value = "1" ( for write protect) or WriteProtect dword value = 0 (to allow to extract data from the PC to the USB)

CEO comments.
Be aware that some software solutions might want to "sell " you "WriteProtect option as "Read Only" misleading term. (option you already acquired with your Windows license)
Read only would mean that any data/code on the USB can only be read (remember Microsoft says write protect NOT read only)
We consider that read only term is sometimes - misleading, misused or misunderstood due to the fact that data/code from the device can be executed also on the PC not only read.

We think that unless you have an airtight network with permission restriction across the board - (no longer common practice on fast growing organizations) and have follow comprehensive Microsoft information on GPO. You should not relay on the above mentioned methods because the methodology used now being widely spread over the internet.
The fact is that unless the network is airtight permission wise - generic code venerates the "security state" could be entered by means of the same "read only" USB device that will finally steal (extract) the information from the PC.

Now with the upcoming of U3 technology that allows the auto execution of the USB device this becomes more of a concern.
We are confident that soon compliance regulation will recommend completely blocking the USB storage devices and only allow specific devices to function as our products do. (we think these recommendation for financial organizations or any organization that holds third party information should go further recommending the company owns the allowed devices) And will also include the recommendation to monitor what's extracted from the pre-approved devices as our product USB Aware (add-on) does.
Therefore our products do not offer "read only" for USB storage as front protection option - of course our software utilizes as backup all means available to finally achieve its primary goal. Protecting your data assets.
