Lookout Mobile Security, a San Franicsco, CA-based cloud-based smartphone security, raised an additional $19.5m in Series C funding.
The round was led by new investor Index Ventures, with participation from Accel Partners and Khosla Ventures.
In May 2010, the company had closed an $11m Series B financing.
In conjunction with the funding, Mike Volpi, Index partner and former Cisco executive, joins Lookout’s board of directors.
Commenting on the funding, CEO and founder John Hering said: “This investment will help Lookout expand to other platforms and develop additional security services to protect consumers”.
