SSL certificate is the first level of defense for your websites on the internet and everyone is aware of the tangibles and intangible benefits of having an active SSL certificate deployed on your website and that is also a reason why you are reading this guide on choosing an SSL certificate for your website.
Focusing on the major steps involved in getting an SSL is divided into 3 major steps. Let us go through them one by one in this guide on SSL.
To obtain a publicly valid SSL, the first and foremost step is to ensure that the domain of the website is registered as it would be verified by Certificate Authorities before issuing SSL certificates. Domains are registered with the help of domain registrars. To get consultation on how to get the best deals on your domain registration and other SSL-related services you can connect with our team at email@example.com and get expert guidance on how to set up your own internal server for internal SSL certificates.
If your domain is not registered it means you are using an internal server name. an internal server name can be a domain or IP address that is basically a part of the private network.
As of November 2015, CAs are not allowed to issue publicly trusted SSL Certificates which contain internal server names or IP address. This is so because these names are not unique, and it becomes difficult for CAs to verify them.
All SSLs in general helps you encrypt the user data sent through the website and provides a secured session, but SSL differs with respect to how much identity information is included in a certificate and how they display in browsers.
There are majorly three categories of SSL Certificate– Extended Validation (EV), Organization Validation (OV), Domain Validation (DV).
Extended Validation Certificates are the most secured as they are only provided when the company’s website meets all the requirements and are identified with the company’s name with a padlock sign in the address bar.
Organization Validated certificates also include the company’s information but are not displayed and users need to view certificate details to view this.
Domain Validated Certificates are the most common type of SSL with the least amount of information in the certificate, but it also means that users can get the impression that the domain is not owned by the company itself although it is verified with a registered domain. Domain Validated SSLs are not suggested for business websites. With the increasing number of phishing attacks happening. It becomes more important for companies to use and promote the use of identified domains (OV or EV) for better security and gain your end user’s reliability.
There are majorly three types of SSL- Single-Domain SSL, Multi-Domain SSL, Wildcard SSL.
Single Domain SSL Certificate secures only the specific hostname on which it gets issued. E.g., if it gets issued on login.abc.com, it will cover login.abc.com only.
A Multidomain SSL Certificate secures all the domains/subdomains which are added to the certificate. There is no restriction on the number of domains or subdomains you want to add to the single certificate, but there may be additional cost involved. E.g., in a Multidomain SSL certificate, you can add www.abc.com, login.abc.com (Subdomain of abc.com), crm.xyz.in (different domain), etc.
A Wildcard SSL Certificate secures an unlimited number of 1st level subdomains of the domain on which it gets issued. For Example: if the domain on which the wildcard certificate needs to get issued is xyz.com, it will cover login.xyz.com, www.xyz.com, crm.xyz.com, anything.xyz.com, etc., but it will not cover 2nd level subdomains such as www.crm.xyz.com, login.user.xyz.com, etc. or any other domain such as www.abc.com.
If you only have a single domain then one SSL is enough with the choice of trust level- OV, EV, or DV. But if you need to secure multiple domains or sub-domains then there is an option to go for wildcard or multi-domain certificates. Using one SSL to cover multiple fully qualified domains would be more manageable and cost-effective.
Based on your requirements and keeping in mind the above steps while making a purchase, choose the right SSL certificate that suits best for your business and its requirements.
