Microsoft introduced the first tablet PC in 2001, which started the tablet computer category. Now any portable device with a touchscreen is considered a tablet. Tablet security is important as tablets store personal data and professionals use them for work. Popular tablet brands include Apple, Asus, Blackberry, Dell, HTC, HP, LG, Motorola, and Samsung. Hackers target tablets through malware, scams, and theft to access users' data, bypassing security protections. Tablet security companies now aim to provide full owner security through preloaded, policy-based apps.
