Microsoft on Monday announced that its “experts on demand” security consulting service, part of its Threat Experts service, has reached the “general availability” (GA) commercial-release stage.

The experts-on-demand capability lets an organization’s security team send questions to Microsoft about suspicious network activities. In response, Microsoft may allow “the SOC to have a line of communication and consultation with Microsoft Threat Experts,” per the announcement. In this case, by “Threat Experts,” Microsoft literally means its security personnel, who get involved in discussing the incident.
