How does PhishCops® work?


PhishCops® is owned by Sestus Data Company. Headquartered in Phoenix, Arizona, Sestus Data Company has created innovative solutions to internet challenges for more than 10 years. Sestus Data Company is entirely self-funded and maintains development and support staff in both the United States and Canada.

The PhishCops® Project
Development of PhishCops® began in 2003 in response to the growing problem of internet account hijacking and identity theft. PhishCops® is copyrighted, patent pending, and is protected by U.S. and international laws.

Most multi-factor authentication vendors have rushed to bring hastily thrown together "image-based" and other similarly vulnerable solutions to market, or are struggling to adapt aging and outdated hardware technology to the modern challenges posed by online multi-factor authentication.

Not us.

Sestus Data Company developed PhishCops® from the ground up, working with internet "backbone" companies and government regulators, merging thoroughly tested unbreakable (and government-approved) authentication algorithms with modern web-based technologies, to create the most powerful and widely accessible multi-factor authentication solution in the world.

Industry Recognition
PhishCops® was recently rated #1 among multi-factor authentication solutions for ease of implementation and overall low-cost of ownership, and it was the only multi-factor authentication solution to receive InfoWorld's highest honor, the InfoWorld 100 Award.

Government Praise
PhishCops® uses unbreakable mathematic authentication algorithms developed by the National Institute of Standards and Technology (NIST) and the Information Technology Laboratory (ITL) under the authority of the U.S. Department of Commerce. For its use of these unbreakable authentication methods in a revolutionary new approach to internet security, the U.S. government has named PhishCops® a semi-finalist for both the 2005 and 2007 Homeland Security Award, the only multi-factor authentication solution ever considered for this award.
