EY is investing $20m to create a central Managed Security Operations Centre capable of predicting and mitigating cyber attacks.
The five-year investment will provide the facility with several technical upgrades and increase the security team's size six-fold to have upwards of 1,200 skilled IT security professionals.
The centre will aim to offer traditional log aggregation and monitoring capabilities, and a "unique integration of commercial off-the-shelf tools" designed to offer "deep insight into a wide range of technologies within customers' networks".
EY will also offer customers an advanced security analytics platform "with a client portal to help ensure its team has full visibility of the operation of the managed centre".
The company claims that the combination of technologies will allow customers to predict and mitigate incoming cyber attacks more easily.
"We have entered an era of targeted cyber attacks. They have increased in number and sophistication to the point that they now make the headlines on a daily basis," said Ken Allan, EY global information security leader.
"Through the Managed Security Operations Centre, our mission is to provide organisations with a highly mature detection and response capability, tailored specifically for their businesses and designed to mitigate against threats from advanced, interactive attackers that put their critical business assets at risk."
Paul van Kessel, EY global risk leader, said that the firm's analytics services are essential because developments in cybercrime make it a matter of when, not if, a business will be breached.
"The question is not if your company will be breached, or even when. More than likely it has already happened," he said.
"Our hybrid model of remote monitoring from India with onsite guidance will allow us to work closely with the client and more deeply investigate incidents, protecting them now and helping them anticipate attacks well into the future."
The announcement follows widespread reports that the cyber threats facing companies are growing at an alarming rate.
Security chiefs from the Met Office, Heathrow Airport and the Economist Group urged firms to prepare for a wave or targeted attacks or face disaster during a panel discussion at Infosec Europe earlier this month.
EY is one of many firms viewing analytics as vital in the fight against cybercrime. David Goulden, CEO of information infrastructure at EMC, argued during a keynote at the firm's EMC World show in May that big data analytics is the future of cyber security.
