The Carlyle Group has acquired ITRS Group, a supplier of real-time systems for monitoring financial communications infrastructure.

Also taking part in the acquisition are ITRS’ founders and management.

Financial terms were not disclosed.

Established in 1997, ITRS has $25 million in annual revenue and offices in London, New York, Manila and Hong Kong, serving banks, brokers, exchanges, hedge funds and data vendors.

ITRS’ Geneos monitoring system has been implemented in 60 leading financial institutions, including eight of the top ten global investment banks.

Carlyle said it will support the expansion of ITRS operations into more countries and more products.

Geneos enables “real-time proactive and predictive monitoring and management, presenting financial institutions with an ultra-high speed overview of their trading environment.’’

Equity for Carlyle’s investment will come from Carlyle Europe Technology Partners II (CETP II), a €530 million fund that closed in November 2008.
