Do you have your online shop, a complex portal or perhaps a business card? Do you have multiple addresses under one domain for better functionality? Great! However, it is worth remembering to secure them with an SSL certificate. However, you do not need to purchase this service for every address belonging to your main website. A Wildcard for your domain is the answer. Find out what it is.
What is a Wildcard?
If you are a website owner, you surely know how important it is to keep your customers', readers' or users' data secure. You have a number of ways at your disposal to win them over, encourage them to take action, and create a kind of protective bubble for any data that is shared. On the surface, there may not be many, but when you look at the features on your portal, you will see that users can perform many actions, such as: registering an account, sending an email, leaving a contact for yourself or placing an order and paying for a product. Every step of the way, a lot of information comes to you (as the owner of the address). Of course, this is collected for a specific purpose, which you must also inform your users about. RODO formulas, a solid database and servers purchased from trusted companies are not enough. You also need to deal with an SSL certificate and, in many cases, a Wildcard. What is this? 
Its function is virtually the same as that of a traditional SSL. A green padlock therefore appears next to the address, indicating that the domain is protected by the certificate. The scope of operation is much broader. The protection applies not only to the main website, but also to all first-order subdomains that appear. Example? If your address is: wildcard.pl, the following will also be protected: sklep.wilcard.pl, b2b.wildcard.pl, blog.wildcard.pl, etc. However, this does not apply to second-order subdomains (also with the prefix www), which require the purchase of a second SSL certificate.
Wildcard certificate - what is its function?
Without proper security, it would be easy for shared data to be intercepted and used in undesirable ways. When a potential customer or reader sees the distinctive closed padlock next to a web address, they are also assured that they are entering a secure site where the data is encrypted. This is what an SSL Wildcard certificate is needed for, especially if there are a large number of subdomains. 
Wildcard - advantages of using it
The Wildcard acts as a form of security for websites through which important data is transmitted. Whether it is a shop, a blog or a business card, it significantly increases credibility and trust. It guarantees the security of data transmission and the protection of payment transactions carried out via electronic banking.
A Wildcard certificate is particularly useful for owners of complex websites that include separate sub-domains. Examples of this would be a blog, a shop or platforms tailored for individual customers or businesses. By investing in a single certificate, you can protect multiple addresses at the same time - without incurring costs for each one separately.
Lower costs are one thing: it is also important to note that data encryption with SSL only requires a single IP address. The certificate is recognisable by most browsers, so it actually reaches 99% of your website users.
