In a deal that is reported to be worth $225 million, the Blackstone Group will buy a majority of the stake in cyber security firm Accuvant from investment firm Sverica International.

The deal will give Blackstone, considered one of the largest private equity firms in the world, 80 percent ownership of the 12-year-old Denver-based company, while executives at Accuvant hold on to 10 percent of shares and Sverica retains a minority stake, according to Reuters.

The deal is expected to close in 30 to 45 days, according to a statement released by Sverica. The Blackstone Group has invested in security firms in the past and have leveraged their services for companies in its portfolio.

Accuvant is known for providing security consulting services as well as software products to clients that include the U.S. government.
