Islandia-based CA Inc., Long Island's largest public company by stock market value, said on Monday that it had acquired Paragon Global Technology, small privately held software maker.

Paragon, or PGTI, produces business software to help companies improve automation. It has four employees and is based in Westminster, Colo. CA did not disclose the terms of the acquisition.

"The proven technology from PGTI seamlessly integrates with CA Workload Automation AE to help our customers improve service levels as they visualize, monitor, analyze and predict the performance of critical workloads,” said Dayton Semerjian, general manager of CA’s mainframe division.

CA, which sells mainframe, security,  storage and other software to large corporations, has about 1,525 employees on Long Island and close to 14,000 employees worldwide.

The company's stock was up 3 cents in early trading, to $26.86 per share.
