A handful of technology firms are primed to step in to repair a badly beaten financial industry. After a $700 billion federal bailout and a vast amount of bad publicity, a growing consensus is emerging in Congress and with the two presidential candidates that financial firms will need more oversight. In particular, the government is expected to target such areas as mortgage lending, loose regulations and unregulated markets. But even before new regulations are in place, chief information officers in the financial sector will be grappling with the recent flurry of bankruptcies and mergers and acquisitions. All this figures to be a boon to tech companies that can help firms improve their data security, update their archiving strategies and reform their compliance and management systems.
