iControl raised $50 million in its D round of funding from Comcast, Rogers Communications, Cisco, Intel Capital, and Tyco International.
Other investors in this round of funding include Charles River Ventures, and the Kleiner Perkins Caufield & Byers iFund. Those two, along with Comcast, Tyco, and Intel Capital, were involved in prior funding rounds as well.
iControl is providing the broadband home management technology at the heart of Comcast's new Xfinity Home Security service. The MSO tested the service in Houston and began rolling it out to additional markets earlier this month.
iControl's OpenHome technology also powers ADT's nationally available Pulse service (ADT is owned by Tyco), and iControl said it is in market deployments with numerous unannounced broadband service providers. Rogers offers home security through a business unit called Rogers Security Systems Inc.
At the close of its D round of funding, iControl has attracted a total of $100 million in funding.
iControl said it will use the new money to further develop its energy management solution and other broadband home management services, while preparing for international expansion.
