Recommended certificate use

Prestigious Secure Site Certificates are used primarily by the banking and finance sectors where maximum security from the largest CA is required. However, e-shops, reservation systems and personal data transmission protection are also suitable. The certificate brings you and your visitors strong security from the world's most respected certification authority.
For the security of banks, payment systems and sensitive information, we recommend the EV certificate with Extended Validation. This makes it easier to identify your site, provides better security guarantees, and effectively protects you against phishing. More details of the Secure Site EV (Extended Validation) certificate.

Premium features of Secure Site Certificate

With the Secure Site certificate, you get the fastest company verification with priority support. With each Secure Site certificate, you also get anti-malware control .

With each Secure Site certificate for your site you get the Norton Secured seal - the most famous security symbol on the Internet. Research has shown that almost 90% of users recognize that a page bearing the Norton Secured seal is safe for them. The symbol is displayed more than a billion times a day and is used by over 100,000 sites in 170 countries. Join them too. We will be happy to help you deploy the seal on your website.

Secure Site Pro product variants allow you to use Certificate Transparency log monitoring for your higher security. If someone issues a certificate for your domain, you will know right away. Pro certificates allows you to use Post-quantum cryptography (PQC) - better encryption resistant to powerful Quantum computers.

Secure Site Pro price list

Secure Site Pro certificate supports not only RSA keys but also ECC keys. You can use algorithms using elliptic curves. The certificate also allows postquantum cryptography (PQC) from DigiCert, which will be replaced by RSA and ECC in the future.

FAQ - Frequently Asked Questions

Each TLS certificate issued must be logged in the Certificate Transparency Log, which has several independent copies. By searching these records, you can see if a CA has issued a certificate for your domain. This can happen in the event of an attempted fraud and will not be protected by a CAA record (restricting authority that may issue a certificate for the domain).

CT log monitoring is the most effective way to find that no one is attempting to abuse (or has abused) your domains and sites. You will immediately learn about a certificate issued without your knowledge.

For more information and settings, please contact our customer support.

Each Secure Site Certificate allows you to place a Norton Secured Seal on the website. Of course, you can use it only on the website secured by this certificate. You need to generate the appropriate code to put it on your site.

You can choose from multiple sizes, dark/light backgrounds, and multiple languages. For assistance with installation, please contact our customer support.

The currently used RSA and ECC algorithms still resist breakthroughs from conventional computers. However, for quantum computers that are much more powerful, these algorithms will not be a problem to break. This is the reason why the postquantum cryptography industry has emerged, which is looking for effective security that resists quantum computers. You can get this security with Secure Site Pro today.

For each Secure Site certificate, you get free anti-malware protection for your site. This means that you can have it scanned from outside by over 70 antiviruses at once. You can obtain the means for this scan from our customer support.

Scanning for malicious code is very important because if someone attacks your site and places viruses or malware on the FTP or source code, they can very easily destroy it. This is because a compromised site will block search engines and browsers very quickly and prevents access to them. Thus, attacking the site has quite fatal consequences.
