Don't panic! There nothing to worry about.
The SOS site is now hosted on a cloud-based server which has its own security certificate but with a different domain name to SOS. Sometimes, individual browsers pick up the security certificate from the server rather than from our web site so you get an alert warning of an 'Untrusted web page'.
This is a simple mis-match of our www.soundonsound.com URL.
You can view the SOS security certificate in our online shop (click the Norton Secured Verisign logo on the top left).
