Microsoft recently signed a deal with FireEye that integrates the security vendor’s iSIGHT Threat Intelligence into Windows Defender Advanced Threat Protection. Microsoft will give FireEye access to all the telemetry data from every device running Windows 10. Microsoft denies the claims, saying that the deal does not include any sharing of Microsoft telemetry. Microsoft is offering this “differentiated intelligence” feature on its newly added service to Windows 10, dubbed Windows Defender..Advanced Threat Protection (WDATP), which helps enterprises detect, investigate, and respond to advanced attacks on their networks.
