It's just a basic fact. Did you know if someone stole your BlackBerry device whether it be a phone or tablet, did you know you can remotly lock it and/or do a complete security wipe making it useless to the thief? That feature alone is amazing. Also the BES is the best. BlackBerry also holds key security patents which makes them the best for mobile security. Features like BBM and e-mail are encrypted and secure which is why major companies choose BlackBerry. Simple net search will give you the details. iOS and Android are a joke when it comes to mobile security. Though Apple's none mobile hardware were well secured at one point, until they recently got hacked.
