Wildcards SSL certificates offer significant benefits for large organizations by securing the main domain and an unlimited number of sub-domains efficiently and affordably. These certificates simplify management, reduce costs, and enhance SEO rankings due to Google's preference for secure sites. With wildcards, companies can future-proof their online security as they expand their sub-domain usage.

4 Major Reasons for Big Organizations
To
Have Wildcard SSL Certificates

2. Wildcard SSL provides myriad benefits for any
big company or organization
• The internet continues to evolve in new and exciting ways. Today, more than
ever, people rely on the worldwide web for everything, whether it’s shopping,
paying bills, seeking healthcare, handling their banking needs, or just for
entertainment purposes.
• This has opened up an incredible range of new opportunities for companies
and organizations.

3. • In today’s world, your website is the backbone of your business. As the
internet has grown, so too have the ways in which businesses use it.
• Nowadays not only is a company’s web presence a great way to reach new
and existing customers, but it provides a way for its employees to conduct
business, whether that’s sending email or accessing payroll information or
even submitting their latest projects.

4. • No matter what kind of business you may be, your website is vital to your success.
• Unfortunately, with the evolution of the internet has come the evolution of hacking and
cybercrime. As more and more information – much of it extremely sensitive – gets
transmitted across the internet, the risk of it being intercepted and either stolen or
manipulated grows.

5. Encrypting Communication with SSL
• Fortunately, SSL or Secure Socket Layers, is a way for companies and
organizations to encrypt and secure their communication. An SSL Certificate is
a digital certificate that is issued by a trusted Certificate Authority.
• It is then installed on a web server and allows the website it’s been issued for to
encrypt all communication between itself and its visitors.

6. • SSL essentially does two things. First of all, it authenticates the certificate holder’s identity.
The CAs are trusted by the browser community – the group of companies behind the most
popular internet browsers, like Chrome, Firefox and Safari – when a company or organization
applies for a certificate, depending on the level of validation they’ve chosen, the Certificate
Authority will then confirm their identity and issue them the SSL Certificate.
• When a browser sees this, it trusts the CA that issued the certificate so it indicates to the
person using the browser that you – having been vetted by the trusted CA – are who you say
you are and can be trusted too.

7. • The other part of what an SSL Certificate does is encrypts. When a browser comes to a site with
an SSL Certificate, the browser and the server that hosts the website perform what is
called “The SSL Handshake.” During this process – which takes just milliseconds – the browser
checks the validity of the certificate, and then negotiates an encrypted connection. During this
connection, the website and the browser exchange what are called “Session Keys.”
• These keys are only good for one visit, and allow each party to encrypt and decrypt all
communication exchanged between them during that visit. This allows them to transmit
sensitive data (like personal or financial information) without it being stolen by a third party. It
is in this way that a business or organization can secure their online communication.

8. Wildcard SSL Certificate
• Now, many big companies or organizations have websites that feature sub-domains. These can
be mail servers, FTP servers, login portals or serve any other range of functions.
• Here’s a brief explanation. When you enter a web address or URL, there are several
components to it. There is a Main Domain, usually the name of the site, for instance Google or
Yahoo. There is a Top-Level Domain, like “.com” or “.org,” and then there are Sub-Domains,
which typically come before the Main Domain and are separated by a period.

9. Examples of Sub-Domains are:
mail.example-domain.com
ftp.example-domain.com
login.example-domain.com
members.example-domain.com

10. • Many companies and organizations make use of sub-domains as part of their websites so that beyond just being customer facing, the site
can also allow their employees to conduct business as well. This is common practice.
• It’s also more difficult to secure, unless you use what is called a Wildcard SSL Certificate.
• Wildcards allow a company or organization to secure its main domain, plus an unlimited number of sub-domains, making them one of
the most versatile product offerings in the SSL Industry.
• When you purchase any SSL Certificate you’re asked to fill out a Certificate Signing Request or CSR. The CSR is essentially an
application. In it you will provide the CA with all of your business details so that it can issue the certificate accurately.
• When you are using a Wildcard, in the field where you would normally enter your domain name, you use an asterisk where the sub-
domains would be. For example: *.exampledomain.com.
• Once the certificate is issued and installed, it will secure all existing sub-domains—no matter how many. And if your company or
organization ever adds more sub-domains during the lifespan of the Wildcard Certificate, simply re-issue it and install it again and the
new sub-domains will be covered too. Wildcards are essentially future proof.

11. 4 Major Reasons to Use a Wildcard
• There’s a lot of great reasons that a big company or organization should consider a Wildcard SSL
Certificate, here are four more:
1. Security of Unlimited Sub-Domains
• As we’ve already stated, Wildcards can secure an unlimited number of sub-domains—as many as
your company or organization has. And again, if you ever add more during the lifespan of the
Wildcard, all you have to do is reissue it and those are covered too. It just doesn’t get any easier
than that.

12. 2. Easy SSL Management
• Normally, securing all of those sub-domains would be a huge headache. You would have to
purchase an individual certificate for each one of them, then you would have to get those
certificates issued, install them all individually, configure your server properly and worry
about keeping track of all of their renewal dates. That’s a lot of different things to consider.
Wildcards simplify everything. Rather than a whole host of certificates, you’re managing one.
One purchase, one issuance, one installation. Done.

13. 3. Affordable Cost
• As you could probably imagine, in the example we just described where you’re securing each
sub-domain on a single certificate the cost of doing business would be quite high. You’re
literally paying a premium on each and every sub-domain you want to secure. Don’t do
that. A Wildcard costs one price, and whether you’re securing one sub-domain of 554 of
them—the price never changes. Think about how much money that saves you!

14. 4. SEO Benefits from Google
• Did you know that Google gives a search ranking boost to websites that are served with SSL?
It’s true, the company announced that SSL would become a ranking signal back in 2014 and
lately, as the browser community pushes for universal encryption, the strength of that signal
has grown. Now you can get up to a 5% SEO boost just from having SSL. That’s low hanging
fruit. Think about it, companies spend thousands of man hours and millions of dollars each
year on SEO strategies—many of which don’t even work. This is a guaranteed 5%. What are
you waiting for?
