Microsoft is planning to acquire RiskIQ, a security software maker, for more than $500 million in cash, Bloomberg reported.
The deal will be announced as soon as the next few days.
San Francisco-based RiskIQ makes cloud software for detecting security threats, helping clients understand where and how they can be attacked on complex webs of corporate networks and devices. Its customers include Facebook., BMW, American Express and the U.S. Postal Service, according to the company’s web site.
RiskIQ has raised $83 million from firms like Summit Partners and Battery Ventures, according to Crunchbase. It was founded in 2009.
The software maker has acquired several companies to expand its security capabilities. Last month, Microsoft bought ReFirm Labs, a maker of technology to secure Internet of Things devices, for an undisclosed amount.
