Date of announcement: Dec. 6

Security solution provider giant Optiv Security is changing private equity hands, with KKR purchasing a majority stake in the company from private equity firm Blackstone Group.

KKR will add Optiv to an $18 billion portfolio that includes information security companies such as Darktrace, Ping Identity and Cylance. While Blackstone will maintain a minority interest in Optiv, company CEO Dan Burns said becoming part of KKR will enable Denver-based Optiv, No. 25 on the 2016 CRN Solution Provider 500, to better help global customers address a full range of cyber-risk and security needs.

Optiv executed three acquisitions of its own in 2016.
