Zynga's chief security officer, Nils Puhlmann, resigned from the company yesterday, according to TechCrunch.

A representative for Zynga told Polygon that the company is "not commenting" on the departure.

According to his Zynga bio, Puhlmann's role was to oversee all security operations and "manage all security risks" at the company. That included product, application, and physical security, as well as security engineering and architecture. Puhlmann is also a co-founder and board member of the Cloud Security Alliance, a nonprofit organization established in 2008 that works to promote security and education for cloud computing. Prior to joining Zynga in 2009, Puhlmann led security teams at companies such as Electronic Arts and Adobe.

This continues a recent spate of departures from Zynga, including leaders such as OMGPOP chief revenue officer Wilson Kriegel; chief marketing officer Jeff Karp; chief technical officer of infrastructure Allan Leinwald; and chief operating officer John Schappert. A poor second-quarter earnings report appears to have triggered the departures.

Earlier this week, Zynga announced the acquisition of developer A Bit Lucky, and the hiring of Mortal Kombat co-creator John Tobias.
