Certificate Authority

A certificate authority (CA) checks whether the applicant is legal and has met all guidelines to get an SSL certificate. These authorities are widely known and most trusted for web transactions. RapidSSL, Thawte, GlobalSign, Symantec is some finest CAs in the web world. The CA verifies the business and provides legitimacy to the business by adding HTTPS to the website URL address.

Domain Secured

Domain security means a certificate can secure the number of domains. Generally, an SSL certificate can secure a single domain (website URL). An SSL buyer can secure unlimited sub domains or add different domains if he/she goes with a Wildcard SSL certificate or SAN certificate.

Root Domain Support

Root domain support offers visitors to access the website without specifying “WWW” in the web address for example, “”. Mostly root domain supports single FQDN (Fully Qualified Domain Name). The FQDN includes two parts: the local hostname and the domain name. For example, is a FQDN, where www is a host name and is a domain name. Root domain support offers visitors to access the website without specifying “WWW” in the web address.

Validation Level

The certificate authority (CA) verifies business on the base of SSL validation types like domain validation, business validation and extended validation.

In Domain Validation, the CA only confirms the ownership of the domain and issues the SSL certificate.

In Business Validation, the CA confirms the business related documents and proves the existence of business to issue the SSL certificate.

In Extended Validation, the CA checks, government records related to business, inquire to authorize a person on behalf of the business, legal verification of business, etc. to issue the SSL certificate.

The Extended Validation certificate is superior to domain and business validation certificate. Therefore, extended validation certificate shows the highest legitimacy of the website or business.

Time to Receive SSL

SSL issuance time may vary depending on the certificate validation. For example domain or standard validation certificate takes only a few minutes in issuance where business validation and extended validation certificate takes 1 to 10 days after issuance process. The issuance time can be stretched due to the validation process that every CA has to perform in order to issue an SSL certificate.

SSL Encryption

According to NIST and CA/B forum, SSL is equipped with 256-bit encryption so that the website will be equipped with strong encryption that never lets any third party to sniff the travelling information between the server and the browser. The size of the 256-Bit key is computationally impractical to break and therefore is deemed as strong SSL security.

CSR Key Encryption

According to NIST and CA/B forum, it is now compulsory to encrypt the root certificate with 2048-bit encryption to avert potential online security risks. The longer the key, the stronger it is against brute force attack. SSL protocol uses an asymmetric encryption that validates the hosts and creates a trust between the client and the server. The asymmetric cryptography key sizes can be 1024, 2048, 4096 and so on.

Server License

There may be a single server license or unlimited server licenses. For load balancing purpose, many certificate authorities offer unlimited server license feature with SSL product. This feature enables the SSL purchaser to install a single certificate on unlimited servers, which gives a single certificate management that is ideally for pilot, test and production environments. Unlimited server license saves money of the website owner by offering the same certificate installation on another server. While there are Thawte and Symantec certificate authorities that offers a single server license for a single domain, therefore for additional server licenses you have to pay money.

SSL Site Seal

SSL Site Seal is a logo that comes free with an SSL certificate, ensures about the security of a website. Once you install a site seal on your website, customers can click and see the certificate information along with time and date stamp and assures customers that the website is safe for dealing online transactions. Many certificate authorities provide site seal with their SSL products.

Reissue Policy

Customers can reissue their SSL certificates in cases where software version is upgraded, ISP changed or private keys are lost or destroyed, encryption changed, certificate information changed. When you request for re-issuance of a certificate, the same contact detail and the domain name of an original certificate will be considered. For re-issuance, you will have to provide domain name and email address. Many certificate authorities provide unlimited re-issuance with the SSL certificate.

Warranty by CA

Different certificate authorities provide warranty on SSL products varies from $10000 to $1750000. The warranty covers the buyer who purchases stuffs from the seller’s website. If the certificate authority fails to validate the SSL purchase, any unknown person buys from such a website and incur losses then this warranty amount will be compensated to the victim.

Refund Policy

When a buyer purchase SSL certificate from the SSL provider, he or she may return the certificate within 30 days of certificate purchase date if he/she is not satisfied with the SSL certificate. The buyer will also get the refund money once a certificate cancellation request is made.

EV Support

SSL certificate that comes with the extended validation feature offers the highest validation and protection to the website. When you have EV SSL, the address bar of your website will look like a green bar. Extended validation requires a vigorous process of verifying the business, which also takes three to ten days after issuance. EV ensures that the website has passed strict validation process as well helps to secure visitors against a phishing attack.

Green Address Bar

When you have EV SSL on your website, the address bar will turn into a green address bar. The green address bar shows the certificate authority name along with a green padlock and when users click on the green bar, it shows information about the certificate. The green address bar ensures customers that the website is secured. The bar shows that the website has the top level of customer trust.

Wildcard Support

When your SSL certificate supports the wildcard feature, you can secure unlimited subdomains with a single certificate. You do not need to spend extra money on an individual SSL certificate. It requires a single domain to be secured with the purchased certificate and the rest sub domains will be automatically secured with this primary domain.

SAN / UCC Support

Many SSL certificate comes with SAN/UCC support that offers you to add and secure extra domains, subdomain, IP addresses or URL to the present certificate. You can secure multiple hostnames or sites on a single certificate with a single IP address. A SAN certificate can secure Exchange 2007 Server or Office Communications Server 2007. SAN is useful in a shared hosting environment where multiple domains target a single IP address. The SAN support saves the time in configuration of multiple IP addresses on the exchange server.

Browser Support

Most of SSL certificates are compatible with recognized browsers to avoid “unknown certificate error”. Whether a customer browses website over the mobile or desktop browser, he/she will have a smooth browsing experience. All certificate authorities have their root certificates in the browser to establish trust over the web. If the certificate is self-signed or issued by an unknown certificate authority, your browser will show a security warning. Mostly SSL certificates carry 99% browser compatibility.
