Protecting mobile devices from hackers is big business, as evidenced by the latest round of funding for Lookout Mobile Security. The nine-year-old startup announced on Wednesday that it has secured $150 million in a new round of financing, the largest so far this year and one of the largest ever for a computer security firm.

It also totals more than all of Lookout's previous funding combined.
