A recent survey of 117 European IT security professionals found that 51 percent of respondents say they don't fully trust U.S.-based clouds, and 62 percent say using a European-based cloud is easier from a regulatory and compliance perspective.

The survey, conducted by Perspecsys at Infosecurity Europe 2014, also found that 47 percent of respondents believe their data is more secure in European-based clouds than in U.S.-based clouds.

Additionally, 62 percent of respondents say negativity towards U.S.-based clouds is justified by reports that the NSA has visibility into such data, and 59 percent don't believe European-based governments have practices that reach the same extent as the NSA.

"The common thread throughout the conversations we had at InfoSec Europe was that there are legitimate concerns around the adoption and use of U.S.-based clouds," Perspecsys CEO David Canellos said in a statement.

"The data from our survey confirms that organizations are taking a serious look at their cloud policies and questioning where their regulated data will be more compliant and secure," Canellos added. "This issue is not going away anytime soon, in fact -- it’s growing."
