Microsoft’s GitHub today announced that it has acquired Semmle, a code analysis tool that helps developers and security researchers discover potential vulnerabilities in their code. Semmle takes a lot of the manual work out of security testing and instead offers a query language that allows researchers to test their code, using the service’s analysis engine. Over time, the GitHub team plans to integrate Semmle closely into the GitHub workflow.

GitHub did not disclose the price of the acquisition, but Semmle, which was originally spun out of research done at Oxford University, officially launched last year, with a $21 million Series B  round led by Accel. In total, the company raised $31 million before this acquisition.
