How secure your old or used iPad is, is determined by the operating system you are using. If your iPad has a iOS 12 operating system you, will need it to be updated to latest version of iOS 0.5.6 since this will keep your security up to date. However, when you purchase one of our refurbished iPads, we upgrade our devices with the most up-to-date operating system to keep them secure and remove all old user data as well.
