It is most likely your company allows some or all your employees to use their own devices in lieu of work-issued laptops, tablets and mobile devices. There is almost no way to enforce a no-BYOD policy outside office walls. Inevitably, someone will receive a text or email that is work-related on their personal device. Somewhere along the line they will open confidential documents. If that device gets lost or stolen, your data goes with it.
Instead of worrying about this, change the landscape entirely. A complete File Sync & Share (FSS) system can ensure that whatever device is used, and from wherever it is used, your data remains secure. Its simplicity means employees will want to use it. More importantly, you can retain control over document sharing. For example, access levels can be passcode protected and restricted, and time limits can be placed on that access. Inactivity timers can be utilized to end unwanted, unsecured viewing. In short, whether you allow BYOD or not, some form of it is occurring and you are facing an inherent risk to data security. Sidestep the entire issue by using a complete FSS platform that supports mobile productivity, high-grade security and quality collaboration tools.
