Securing Intellectual Property in Excel

Excel spreadsheets often contain proprietary information and business logic that must not fall into unauthorized hands or be modified by users of the spreadsheet. Unfortunately, spreadsheets are extremely vulnerable to inadvertent (or intentional) dissemination via internal file sharing portals, email, and thumb drives. Though some protection of cells and sheets can be enabled within Excel, implementing these require expertise and often involve significant effort, and can still be defeated. Furthermore, the spreadsheets are still functional, and this by itself may present a liability to your organization should it get into the hands of unauthorized parties.


In short, the sharing of spreadsheets in native Excel format is rather like sharing the source code for a mission-critical app developed specifically for your company.

EASA completely eliminates this issue, as direct access by end users to the actual spreadsheet is eliminated. With EASA, the spreadsheet is rendered as a browser based application (much like a website page), which is connected to an instance of Excel running on a secure server. With a web app, you can control exactly which parts of the spreadsheet are visible, what data can be changed, and which users within your organization can view or use the app.

Unlike other approaches that require translating Excel spreadsheets into another format, EASA runs the original spreadsheet on a secure sever. This means included VBA and macros that perform calculations will continue to operate as is. It also means you don’t have to scrap your valuable spreadsheets to replace them with expensive new custom coded solutions, or manually rebuild the logic into a new software tool.
