How safe is the intellectual property (IP) you have invested in your spreadsheet formulas? Can contractors or employees steal your IP by copying your spreadsheets (or even just the formulas)? Do you want to send spreadsheets to customers but want to prevent them gaining the knowledge of how they work?
Unfortunately, Microsoft Excel® has very little security built in to it. Excel does provide password-based 'protection' of workbooks, worksheets (enabling cell locking and hiding of formulas), macros and add-ins. The level of protection provided, however, is relatively low, and provides a first line of defense only. The Excel-based protections can all be broken fairly easily using un-protect programs and services readily available on the internet. Microsoft itself has stated that the password-based locking and hiding features “are not intended to secure or protect confidential information in Excel. These features are merely meant to obscure data or formulas that might confuse some users or to prevent others from viewing or making changes to that data” [http://office.microsoft.com/en-us/help/HP052388541033.aspx].
An ideal solution would be one where spreadsheets were encoded so that the IP encapsulated by the spreadsheet formulas was secure, but where authorized users could operate encoded spreadsheets as normal. Until recently, attempts to provide strong security were very expensive, and were essentially targeted at large corporate users.
