The main purpose of the digital certificate is to ensure that the application belongs to the entity to which the certificate was issued. The Alexa Internet digital certificate does not guarantee that a signed application is safe to run, but rather informs the user that the software was digitally signed by Alexa Internet and verified by a trusted Certificate Authority (CA).
Alexa Internet, Inc. is a California-based subsidiary company of Amazon.com that is known for its toolbar and Web site.

Founded in April 1996, Alexa Internet grew out of a vision of intelligent Web navigation constantly improving through its users. Since then, our Alexa users have downloaded millions of Toolbars, and Alexa has created one of the largest Web crawls, and developed the infrastructure to process and serve massive amounts of data. For users of the Alexa Toolbar and our website, the results are products that have revolutionized Web navigation and intelligence. For developers, this has led to a set of tools unprecedented in scope, allowing whole new services to be created with Alexa data. Alexa could not exist without the participation of the Alexa Toolbar community. Each member of the community, in addition to getting a useful tool, is giving back. Simply by using the toolbar each member contributes valuable information about the web, how it is used, what is important and what is not. This information is returned to the community as Related Links, Traffic Rankings and more.”
