DT, Qualcomm and Peter Thiel invest in mobile threat specialist Lookout

Mobile security outfits are a dime a dozen these days, but one particular San Francisco startup is garnering a lot of interest from both telecom and Valley heavyweights. Lookout on Thursday said it has secured a huge $55 million strategic financing round led by Deutsche Telekom with participation by Qualcomm Ventures(s qcom), Peter Thiel’s Mithril Capital Management and Greylock Partners.

Existing Lookout investors Accel Partners, Andreessen Horowitz, Index Ventures and Khosla Ventures also chipped in. Lookout raised a $40 million round this time last year, adding to the $36 million it hauled in from its A-through-C rounds between 2009 and 2010.

Lookout has developed a cloud-based security service that detects and blocks malware and virus threats, locates lost phones and wipes devices clean if compromised. While Lookout offers its Android(s goog), iOS(s aapl) and Kindle(s amzn) apps directly to consumers for download, it’s made a big business out of selling its service to carriers, including Deutsche Telekom, Orange(s oran), Sprint(s s), and T-Mobile(s tmus).

Later this year, Lookout plans to launch Lookout for Business, which will extend its consumer threat protection to enterprises. Mobile security in the enterprise will be one of the topics we discuss at GigaOM’s Mobilize conference next week, in particular how exposed our data and devices become as the smartphone becomes a remote control for the internet of things.
