About Dan Geer

Dan Geer was an American computer scientist, known for Certco (financial services), Open Market and Project Athena.

Dan Geer is a computer security analyst and risk management specialist. He is recognized for raising awareness of critical computer and network security issues before the risks were widely understood, and for ground-breaking work on the economics of security.

Career Geer is currently the chief information security officer for In-Q-Tel, a not-for-profit venture capital firm that invests in technology to support the Central Intelligence Agency.

In 2003, Geer's 24-page report entitled "CyberInsecurity: The Cost of Monopoly" was released by the Computer and Communications Industry Association (CCIA). The paper argued that Microsoft's dominance of desktop computer operating systems is a threat to national security. Geer was fired (from consultancy @Stake) the day the report was made public. Geer has cited subsequent changes in the Vista operating system (notably a location-randomization feature) as evidence that Microsoft "accepted the paper."

Geer received a Bachelor of Science in Electrical Engineering and Computer Science from MIT, where he was a member of the Theta Deuteron charge of Theta Delta Chi fraternity. He also received a Sc.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) Verdasys

In 2011, Geer received the USENIX Lifetime Achievement Award.
