According to Comodo Dragon, a new open source web browser, more than half of all sites using SSL certificates may be unsafe. This is because these days, it’s very easy to buy an SSL certificate and validate your website.
This trend is mainly a result of a huge spike in domain-validated SSL certificate sales. Offered by a number of registrars, including Go Daddy, these SSL certificates are less safe because anyone can get one. There is no verification to ensure the site in question is safe.
So in essence, just because a site has an SSL certificate doesn’t mean you can trust it. SSL security and the value of buying a certificate have been undermined.
