Le site omniture.com est-il sûr ?

http://www.avgthreatlabs.com/us-en/website-safety-reports/domain/omniture.com/ 30-day safety report for: omniture.com Surf with caution This website has SSLv3 support enabled and may be vulnerable to data leakage. (updated Feb 27, 2016 GMT) Types of Malware Found 1 SSLv3 support ***** SSLv3 support Summary This vulnerability relates to version 3 of an encryption technology known as SSL (Secure Socket Layer). When a browser connects to a webserver that supports this older technology there is a risk that if SSLv3 is the primary encryption or the connection security falls back from the newer TLS technology to SSLv3 then an attacker could potentially exploit this vulnerability. While it is unusual for websites to still be using SSLv3 as the default encryption technology, it is possible for an attacker to cause connection failures that force the server to default back to the older, insecure, technology. By exploiting this vulnerability, an attacker could gain access to things like passwords and cookies, enabling him to access a user’s private account data on a website.

Unlike Google Analytics, which has a weak privacy policy and correlates data across sites, with adWords, etc, Omniture data belongs to the web site you're visiting, that is using the service to analyze its own traffic. If you see an Omniture cookie, it means the site owner has chosen to pay to protect your privacy rather than accept Google's "free beer, no privacy" approach.
