On August 27, 2015, Cisco acquired OpenDNS for US$635 million in an all-cash transaction, plus retention-based incentives for OpenDNS. OpenDNS's business services were renamed Cisco Umbrella; home products retained the OpenDNS name. Cisco said that it intended to continue development of OpenDNS with its other cloud-based security products, and that it would continue its existing services.
Until June 2014, OpenDNS provided an ad-supported service and a paid advertisement-free service. The services are based on software proprietary to the company.
