The 2017 Trading Tech 40: Donal Byrne

As financial markets and technology infrastructure as a whole have gotten bigger, faster, and more complex, Corvil has grown up as a supplier of analytic tools essential to monitoring and safeguarding critical networks. Virtually every major market operator is a customer of Dublin-based Corvil, which reported 50 percent sales growth last year. In October it introduced its latest set of analytic capabilities for transparency, surveillance, and compliance in trading businesses, dubbed machine-time analytics.

Machines are capable of taking actions a million times faster than humans, notes Donal Byrne, 51, the company's CEO since 2002. Streaming analytics are thus required to "act on the time scale of the machines," he says. Cybersecurity requires the same and is another growth area. Last year Corvil partnered with endpoint security company Carbon Black to offer an integrated cyberthreat detection, analysis, and response platform.
