Symark Software, maker of security applications that only allow network access to IT professionals, has acquired a smaller rival, BeyondTrust, for a little over $20 million. Following the merger, the company will operate under the BeyondTrust name, hoping that the boost in customers and revenue will carry it to a lucrative public offering next year.

Agoura Hills, Calif.-based Symark is owned by Insight Venture Partners. The deal will also give the company a Windows-version of its technology. Before, it only offered security solutions for Linux and Unix.
