Google is set to invest in secure messaging start up Symphony, primarily used by major financial entities and valued at $650 million, the Wall Street Journal said Tuesday.
Symphony uses encryption technology, allowing firms to communicate securely on a centralised platform.
Neither Google nor Symphony commented on the report.
Symphony launched globally last month as a rival to more expensive terminals from financial information provider Bloomberg, whose services are widely used by finance professionals and investors, who typically pay several thousand dollars a year for the service.
Symphony charges businesses with more than 50 users $15 per user per month.
