Piper Jaffray analyst Andrew Nowinski views Equifax's (EFX) a cybersecurity breach as positive for Symantec (SYMC), FireEye (FEYE) and Proofpoint (PFPT). "Mega-breaches like Equifax not only create awareness for the security space, but typically result in an increase in spending by enterprises," Nowinski tells investors in a research note. Equifax offers a number of credit monitoring and identity theft protection services, similar to Symantec's LifeLock, the analyst points out. He believes Symantec should see a benefit to its LifeLock business. Nowinski adds FireEye's Mandiant has been reported to have been contracted to investigate the breach. The analyst's top picks remain Proofpoint and Symantec.
