Santa Clara, Calif. - April 17, 2001 - Americans who use the Internet are most fearful of Social Security and credit card numbers being stolen by criminals and believe the Internet is where their personal information is most vulnerable (41%), followed by dishonest phone order agents in a distant second (19%), according to the results of a poll released today. The poll was commissioned by Sanctum, Inc., the established leader in automated Web application control and security software, and conducted by Harris Interactive (Nasdaq: HPOL), the global leader in online market research.

"These results show that Americans are genuinely concerned—and should be—about the way their information is protected online," said Peggy Weigle, CEO of Sanctum. "Even savvy Internet users are confusing privacy policies with security policies, and a privacy policy simply does not ensure that personal information is protected at all. It is vital to proactively secure Web sites against malicious attack by today's hackers, who are motivated by greed. For them, personal information is the "crown jewel"-exactly what they need to steal identities, manipulate funds in bank accounts and falsify credit information."

"Any personal information on the Internet is vulnerable," added Larry Johnson, former analyst with the CIA and the State Department's Office of Counter-terrorism. "Your personal identity, your credit card number, things which only you would know, can now be easily accessed by someone who wants it if you don't take appropriate steps to make sure it's protected. Be very, very cautious about what information you put out there [on the Internet] and make sure it's going through a system that is secure."

According to the survey results, 41 percent of the 2,951 U.S. respondents were most concerned about Social Security numbers falling into the wrong hands, followed by credit card information at 29 percent. These results bolster the findings of a report issued earlier this month by the Pew Internet and American Life Project, which showed that 87 percent of Americans surveyed were "concerned" or "very concerned" about the online theft of personal information.

The results remained essentially the same across most educational and income levels, although those with a high school degree or less and those whose household income was $35,000 or lower were the least likely to trust the Internet.
