Symantec announced general availability of its O3 cloud-based single sign-on (SSO) and authentication service. The O3 service adheres to a concept company CEO Enrique Salem outlined exactly a year ago at RSA 2011. O3 can manage SSO access control and log management, plus strong two-factor authentication from a variety of third-party vendors. In the future, O3 capabilities will expand to include data-loss prevention and encryption related to specific traffic the business wants to protect.”]
