A Detailed Guide on Technical Differences Between Wildcard SSL and Standard SSL certificates

You don’t need to purchase a separate certificate for each of your domains, though. Understanding Wildcard SSL vs. Standard SSL certificate possibilities is essential to avoid squandering resources and money on individual certificates for all of your domains.

What is Standard SSL Certificate?

A single-domain SSL certificate is most commonly referred to as standard SSL. Your domain names, such as www.domain.com or domain.com, are secured by this specific sort of SSL certificate. The unique domain SSL certificate ensures that whenever a user visit with www.domain.com, the information/data flowing from their client (browser) to the server (website) is not stolen by a scammer.

Use cases of standard SSL certificates

Although they pass through the public Internet, digital interactions are kept private with the use of SSL certificates, which also offer users the confidence to enter their private data on your site.

You must safeguard the data whenever you request website visitors to sign up, provide private data such as debit or credit card numbers, or access your confidential details like financial or health reports. Additionally, you must reassure consumers that your site is legitimate.

Additionally, SSL is utilized for server-to-server interaction, web-based applications, email servers, and other things.

Technical Differences Between Standard SSL and Wildcard SSL

Technical Specifications

A server certificate with a typical SSL certificate has a basic level of authentication. A regular SSL certificate will not really offer as thorough of a company evaluation as an OV or EV certificate while using the same grade of tech to safeguard the interaction.

Uses for

Regarding wildcard SSL vs standard SSL, freelancers, bloggers, and small businesses who own a website with a single domain use a standard SSL certificate. Meanwhile, wildcard SSL certificates are used by SMEs, eCommerce website owners and large enterprises that need to secure a server and unlimited sub-domains.


In comparison to a company-validated certificate, a commercial standard SSL certificate typically has a smaller guarantee. The general guideline is that the warranty amount should increase as the danger does. The guarantee for a regular SSL certificate tends to be lesser because, in practice, only websites with minimal risks should use them.

Encryption Protocols & Algorithms

All of the certificates you purchase from a reputable company will use the most recent SHA-2 algorithm and deliver up to the standardized 256-bit encryption as well as a 2048-bit RSA signature code. So, both Standard and Wildcard SSL certificates will all have the same technical setup.

Validation Levels

Domain validation (DV), the lowest degree of certification, applies to all ordinary SSL certificates. In this case, the applicant merely needs to demonstrate domain authority. In comparison to other forms of SSL certificates, the domain verification system is the simplest and quickest.


The cost of a standard SSL certificate ($2.99 per year) is comparatively lower than the cost of a wildcard SSL certificate ($19.99 Per Year). The reason is simple: Wildcard certificate ensures the security of a domain as well as unlimited sub-domain, which the standard one does not.

Issuance Time

There is no such difference in the issuance time of these certificates. When it comes to standard SSL vs wildcard SSL, you must know that both come with an issuance time of around 15 minutes. However, the fact that wildcard certificates involve a fast verification process means the certificate may get issued a minute or two earlier than the standard SSL.

When To Use Standard SSL and Wildcard SSL Certificates

If your website requires logging in, SSL is necessary to protect user identities and credentials. SSL is required if you are deploying forms that request sensitive user information to prevent hackers from stealing your customers’ data. You might require an SSL certificate if your website conducts business online.

Local firms, freelancers, bloggers, test domains, and other entities needing a protected HTTPS connection for a particular domain are best served by domain validation certificates. A standard DV Certificate cannot secure many domains and subdomains, which is what a larger corporation entails.

Additionally, the Standard DV SSL Certificates doesn’t really enable the green address bar or offer an identity guarantee. Depending on your individual needs, it’s advisable to use Wildcard SSL Certificates for firms who are seeking those additional benefits.
