With Google\u2019s ongoing effort to mark websites running on HTTP as \u201cNot Secure\u201d, SSL\/TLS certificates have become synonymous with website security. Consequently, people often turn to commercial and free wildcard SSL certificates as well as single domain certificates to encrypt their web traffic.<\/p>\n\n\n\n
But what do SSL certificates do exactly? SSL\/TLS certificates: <\/p>\n\n\n\n
There are different types of SSL\/TLS certificates, and a wildcard\nSSL is one of them. Before getting into the differences between a free wildcard\nSSL certificate versus a paid one, let\u2019s explore why we might need one in the\nfirst place!<\/p>\n\n\n\n
A wildcard SSL certificate secures a website along with an unlimited\nnumber of subdomains at a specific level using one certificate. It\u2019s a\ncost-effective solution that makes it easier to secure and manage multiple\nsubdomains. A single certificate signing request (CSR) can be generated for the\nmain domain and its subdomains. Only this particular certificate needs to be\nrenewed and maintained in place of multiple SSL\/TLS certificates for individual\nURLs. <\/p>\n\n\n\n
Regardless of whether you choose to use a paid or free wildcard SSL certificate, it\u2019s easy to see the benefit of it. But before you rush off to get a paid or free certificate, there are a few more things to know.<\/p>\n\n\n\n
A wildcard SSL certificate is a public key certificate that secures\nthe primary domain and an unlimited number of subdomains at one level.<\/p>\n\n\n\n
Consider the following example: <\/p>\n\n\n\n
Todd owns a website named domain.com with the following subdomains: <\/p>\n\n\n\n
These are all first-level subdomains that can be covered under the\nsame wildcard – *.domain.com. <\/p>\n\n\n\n
However, wildcard SSL certificates are not the best choice for\nsecurity-critical systems since a private key is shared amongst all subdomains\nacross all servers<\/a>[CC1]<\/a> . You can, instead, opt for a multi\ndomain SAN certificate<\/a> and list your subdomains as SANs. With multi domain\nSAN certificates, you also have the option of choosing any of the three\nvalidation levels. Wildcard SSLs are never issued together with extended\nvalidation (EV) certificates for security reasons.<\/p>\n\n\n\n Paid wildcard SSL certificates offer additional benefits apart from securing unlimited subdomains on a single certificate. For example, they can be issued with two validation level options \u2014 as a domain validated (DV), or an organization validated (OV) certificate.<\/p>\n\n\n\n Commercial wildcard certificates also come with added benefits and features that a free wildcard SSL certificate provider can\u2019t support \u2014 such as a warranties if the encryption fails (highly unlikely), 24\/7 customer support, complimentary trust seals, etc.<\/p>\n\n\n\n The Internet Security Research Group (ISRG) is the organization behind Let\u2019s Encrypt, which issues SSL\/TLS certificates free of charge. A free wildcard SSL certificate offers the same level of encryption but without any warranty or support. Furthermore, the certificate is only valid for a period of up to 90 days (after which time it needs to be renewed).<\/p>\n\n\n\n As of now, Let\u2019s Encrypt has an issuance rate limit of 50 certificates per registered domain per week. With paid certificate, there is no such limitation. Additionally, free wildcard SSL certificates can only be issued for the most basic validation level i.e., as a domain validation certificate. <\/p>\n\n\n\n If you are on an extremely tight budget and can risk downtime for your website, it\u2019s a pretty decent option as opposed to not having an SSL\/TLS certificate at all. But be sure to carefully manage and renew the certificates on time to avoid certificate outages that can leave your site vulnerable.<\/p>\n\n\n\n The table below makes a quick comparison between free wildcard SSL certificates\nand their paid counterparts. <\/p>\n\n\n\n Free wildcard SSL certificates come at zero cost, and arguably that is a huge benefit in and of itself. Based on the type of business you own, you need to ask yourself if you can live with no warranty, site seals, or customer support. Realistically, if the cost isn\u2019t your only determining factor, and you can consider looking at some affordable paid SSL alternatives, our recommendation is to err on the side of caution.<\/p>\n\n\n\n Save 50%<\/strong> on Sectigo Wildcard SSL Certificates.
