Dan Geer is one of a small number of pioneers in the security world that raised critical issues before others could see a risk emerge. He is most recently known to many as the chief technical officer for @stake, a computer security consulting company that did work for large banks and technology vendors including Microsoft. He published a 2003 paper arguing that Microsoft was a monoculture; he was fired the day the report was made public.

The 24-page report entitled "CyberInsecurity: The Cost of Monopoly" was released by the Computer & Communications Industry Association (CCIA) which made the argument that Microsoft is a threat to national security.

Geer has a Ph.D. in biostatistics from Harvard, and has worked for

• Health Sciences Computing Facility, Harvard School of Public Health
• Project Athena, MIT
• Digital Equipment Corporation
• Geer Zolot & Associates
• OpenVision Technologies
• Open Market
• Certco
• @stake (acquired by Symantec in November 2004)

Geer is currently employed by Verdasys.

He lives in Cambridge, Massachusetts.
