KLAS: Imprivata, Microsoft/Sentillion Lead SSO Market

Despite a slight decline in SSO customer satisfaction ratings over the past two years, providers generally report the technology to be a valuable purchase, especially related to workflow simplification, according to new KLAS report, “Single Sign-On: To Identity Management and Beyond.”

Imprivata took the lead with a score of 83.6 out of 100, followed by Microsoft (83.2) and HealthCast (82.4). Carefx and Novell are also highlighted in this report. Addendum information is included for IBM, Passlogix and FairWarning.

The report notes that some SSO ratings might be a reflection of the hardware used for strong factor authentication, i.e. biometrics, proximity cards, and smart cards. Difficulty getting biometric products to work as needed has many providers learning toward proximity tools, according to the report.

Merger and acquisition activity is reframing the SSO market, KLAS noted. IBM bought Encentuate in 2008, and Microsoft acquired Sentillion at the end of 2009. Oracle has acquired Passlogix. Most recently announced is the Novell acquisition by Attachmate.
