More than one third of financial service industry websites experience at least one serious vulnerability, such as a data exposure, every single day, according to Santa Clara, Calif.-based WhiteHat Security's Website Security Statistics Report.

The report provided a state of website security and the issues that organizations must address in order to safely conduct business online. The 2015 report found that while no true security best practices exist, the key is in identifying the security metrics that mean the most to the organization and focusing on those activities to remediate specific vulnerabilities.

Through examining web application vulnerabilities of more than 30,000 websites managed by WhiteHat Sentinel, researchers gathered the following statistics: 35% of finance and insurance sites are always vulnerable, meaning sites had at least one serious vulnerability exposed every day of the year. Only 25% of finance and insurance sites had one or more serious vulnerability exposed less than 30 days of the year. Insufficient transport layer protection was the most likely vulnerability in the financial/insurance vertical.
