I have used the Book-Supplier.co.uk for over a decade and have found the website to be safe, secure and easy to use.
The BBC website is one of the safest places online to watch TV programs. The site operates an SSL certificate and has thousands of respectable journalists.
The British Museum website provides safe and secure content for the general public to access. It is clearly laid out and the pages all operate from a secure https protocol.
I use Whatacca.com for collecting ideas on football bets. The website operates on an SSL https certificate and the moderators seem to be very proactive in making the resource safe and friendly.
