CA Technologies Monday said it was buying two smaller privately-held software makers, continuing its expansion beyond traditional mainframe computer programs.

The Islandia company, Long Island's largest by stock market value, has reached an agreement to acquire Layer 7 Technologies and has bought Nolio of Manhattan. CA did not release terms of either deal.

Layer 7, of Vancouver, British Columbia, has about 150 employees and develops software to manage and protect systems that companies use to transmit data to customers via smartphones, iPads and other devices. This type of program, called an application programming interface, or API, forms the backbone of most transactions made via mobile applications.

"We use APIs every day, whether accessing flight data from our mobile device, using Google Maps from a hotel website or making payments online," said Mike Denning, CA's security general manager.

Nolio, has several dozen employees and develops programs to help companies test software and iron out glitches before fully installing it on their systems.

Over the last five years, CA spent more than $2 billion to acquire dozens of smaller companies, as it expands into cloud computing and other growing sectors.

CA's stock rose 12 cents Monday to $24.48. The company has a total stock market value of $11.2 billion. It employs 1,525 people on Long Island and close to 14,000 worldwide.
