Security breach, announced by information broker giant LexisNexis, could affect more than 300,000 customers with more than 15,000 clients from Florida.

An extensive internal review by the company unveiled that at least 310,000 customers were affected by the security breaches.

The company said it regrets that the consumers may be affected by the breaches. ’’We regret that consumers, who traditionally are the primary beneficiaries of our risk management products and services, may have been affected by these events,’’ said Kurt Sanford, head of the company’s corporate and federal markets group. ``We have taken a number of significant actions in recent weeks to further guard against these types of fraudulent intrusions at our customer sites and to enhance our security procedures and policies overall,’’ he added.

LexisNexis announced last month that its Seisint unit faced the exposure of more than 30,000 consumers’ Social Security numbers, drivers’ license numbers, names and addresses.

The information about some more 280,000 customers was stolen, the company reported.
