1. A system comprising: a symbol based encryption module adapted to encrypt on a per symbol basis some or all of the data within a data record, data file or document, wherein the encryption is invariant on a per symbol basis and at least some of the data in the file or document remains processable in a Software as a Service (SaaS) environment, and wherein search terms to be used to search the some or all of the data within the data record are converted using the symbol based encryption module and searching is performed utilizing the converted symbols within the SaaS environment, wherein symbols to be encrypted are first converted into lower case letters, encrypted, and then case format information relating to the unencrypted symbols is then encoded onto the encrypted data; a sensitivity module communicatively coupled with the symbol based encryption module to evaluate the data to determine a sensitivity level for multiple components of the data, wherein encryption of the multiple components is performed based on the sensitivity level corresponding to the component.
