According to CloudLock's Q4 2015 Cloud Cybersecurity Report, 83 percent of technology firms say excessive sharing in the cloud is a top cyber security concern, and are concerned as a result with ensuring access permissions to sensitive data are granted appropriately.

The same is true of 77 percent of organizations in K-12 education, 75 percent of financial services firms, 72 percent of healthcare organizations, 70 percent of manufacturing companies, and 66 percent of retailers.

Still, the survey of 10 million users found that only 5 percent of organizations take active steps towards protecting credentials, including attempts to identify instances of exposed credentials in public cloud environments.

"While all industries are certainly evolving to make security a priority, each industry faces different risks and concerns that need to be addressed in a very specific and nuanced manner," CloudLock CEO and co-founder Gil Zimmermann said in a statement. "We're hoping this latest data will provide guidance for those who are wondering how they stack up against their peers, and possibly make them take notice of where they are falling behind when it comes to protecting critical information and assets."

Just 10 percent of technology firms are concerned with protecting users' personally identifiable information (PII), such as Social Security numbers, birthdates and ID numbers -- compared to 77 percent of organizations in higher ed, 70 percent of organizations in K-12 education, and 59 percent of financial services firms.

And just 30 percent of healthcare organizations are concerned with protecting payment and credit card information, compared to 61 percent of organizations in higher ed, 55 percent of financial services firms, 55 percent of retailers, and 41 percent of technology firms.

Separately, a SailPoint survey of approximately 100 organizations at the Gartner Identity & Access Management Summit found that 91 percent of respondents have mission-critical applications currently residing in the cloud, and 99 percent plan to increase their cloud app usage in the next few years.

Still, 60 percent of respondents still plan to maintain at least half of their core applications on premises.

"Organizations of all sizes are rapidly adopting cloud applications as part of their business strategy," SailPoint president and founder Kevin Cunningham said in a statement. "There are many benefits to this strategy, but organizations need to maintain a single view into 'who has access to what' in order to manage risk."
