Please make sure the server name you used to sign up is the same as the web site you placed the web site code on. The most common cause for the seal code not being detected is if you tried to sign up the server "example.com" but by mistake placed the seal code on "www.example.com".
Other possible causes for the seal verification not working:
1) When you access your site, if you access www.domain.com but you are then redirected to www2.domain.com, that means www2.domain.com will need to be enrolled. Always sign up the domain that is the LAST domain in the chain, if the forwarding is automatic.
2) If you enrolled www.domain.com the seal code should be:
<a href="https://seal.beyondsecurity.com/vulnerability-scanner-verification/www.domain.com"><img border=0 alt="Website Security Test" src="https://seal.beyondsecurity.com/verification-images/www.domain.com/vulnerability-scanner-2.gif"></a>
Using anything else will not work. Make sure the code is correct or the seal will not be detected.
3) If your site www.domain.com redirects to a non-standard port, for example to https://www.domain.com:8081/ or to a sub directory such as http://www.domain.com/somedirectory/ you should contact us at: firstname.lastname@example.org to request a manual verification.
