Beyond Trust, a Carlsbad provider of security and access control software, said it acquired eEye Digital Security, with an office in Irvine, for an undisclosed price on May 8.

Through the acquisition, Beyond Trust, which had 2010 annual revenue of $50 million, will deliver unmatched solutions in protecting companies from internal and external threats, said John Mutch, Beyond Trust’s chief executive.

Both companies have high profile clients, with Beyond Trust counting about half of those listed on the Dow Jones Industrial Index, and eEye used by the U.S. Department of Defense for eight years, the company said.

The company didn’t disclose eEye’s revenue or employment. Mutch said last year that Beyond Trust had about 140 employees worldwide including 35 in Carlsbad.
