Lookout

For securing 15 million smartphones against mobile threats and reuniting lost phones with their owners. The San Francisco-based company is adding new customers at a rate of more than one million per month. After years of providing security services for BlackBerry, Windows 7, and Android phones, in October Lookout launched its free iOS app for securing data that iPhone and iPad users store on their devices. Last June it launched a new feature to protect users from online threats while web browsing on their mobile phones. Lookout’s cloud-based protection system is powered by its Mobile Threat Network, which quickly analyzes threat data worldwide and block threats as soon as they emerge. Last year they unveiled the Lookout API, which gives partners–including Verizon Wireless–access to threat data, ensuring all apps in their app stores are screened against Lookout’s databases. Lookout now comes pre-loaded on T-Mobile devices and just announced a partnership with Telstra, Australia’s biggest mobile operator, to come pre-loaded on Telstra devices as well in 2012.
