JPMorgan Chase, American Express and HSBC said they are leading a $40mn round into Menlo Security; banks are usually a lot more secretive about security investments but they see a wider industry potential in using isolation technology; the technology can better defend against phishing attacks which account for most breaches as employees click on a fake link that then causes malware to infect the computer; when a user clicks on a link they open a browser that really is a one time instance in the cloud and prevents malware from downloading onto a computer; while some big banks have started using the technology more there has not been a significant rush yet.
