1. Best free SSL certificate providers in October 2023

1.1 Let’s Encrypt

Let’s Encrypt


  • They are free. This is a significant advantage for those site owners who cannot afford a paid certificate but they strive to provide their visitors with a secure connection. Let’s Encrypt does not require the installation or renewal of the certificate. If you want to, you can make a donation on the project website.
  • Certificates are issued automatically. You can allow the Let’s Encrypt client to independently download, install, and renew certificates. However, if you are worried about them setting up your server, you can do it manually.
  • Reliability and safety. Although Let’s Encrypt SSL certificates are free, it does not mean that their encryption level is lower than that of paid certificates. Let’s Encrypt adheres to the highest encryption standards and offers certificates of high reliability.
  • No extended validation. When issuing a certificate, only the client’s ownership of the domain is verified. Thus, anyone on the Internet can create a certificate with the name of any organization and pretend that the site is related to it.
  • Certificates are issued for a total of 90 days. This is rather an inconvenience for users, rather than a significant disadvantage of a certificate. The fact is that by issuing a certificate for just 90 days and not for 1 year, Let’s Encrypt tries to reduce the damage caused by those keys and certificates that were issued by mistake. Having a shorter validity period, such certificates will cause less damage than the ones issued for a year.
  • Compatibility issues. Let’s Encrypt certificates are not compatible with earlier versions of operating systems. In addition, compatibility issues may also happen with older versions of mobile software. To make sure that there will be no problems with your operating system or mobile firmware, check whether they are on the list of compatible devices and programs on the Let’s Encrypt official website.
  • No customer support. You will not find chat or telephone support on their website, only technical documentation in English. Some questions about these certificates are discussed in the thematic forums and it is there that you can find answers to your questions.
  • No warranty or monetary compensation. Unlike commercial certificate centers, Let’s Encrypt provides no guarantees. If the certificate is cracked or someone loses money due to a certificate issued to the fraudulent site, the losses will not be reimbursed.

1.2 Cloudflare One-Click SSL

Cloudflare One-Click SSL


Most users know Cloudflare as a CDN provider, although it also provides a free SSL certificate service. If you use free Flexible SSL from Cloudflare, traffic will be encrypted from the visitor to the Cloudflare server, but not from the CloudFlare server to your one! This makes it not as reliable as a high-grade SSL certificate. Cloudflare still provides full SSL support, but in order to use it, you need an SSL certificate installed on your source server. As long as you do not collect and process confidential information on your website, the SSL from Cloudflare is fine and will provide enough security. This is also one of the most recommended free SSL providers on Reddit and Quora.

  • Free SSL;

  • The free SSL does not apply to subdomains of the * subdomain;
  • The free SSL will not work on Windows XP and older versions.
  • The traffic from Cloudflare to your server is not encrypted, that is, wholesale providers, trunk providers, and the NSA can still read all requests in text format.
  • Traffic is subject to man-in-the-middle attacks (MITM), where another server can impersonate another server and receive its traffic (although this problem also applies to the “Full” SSL setting, you will need to change to “Strict” in order to avoid this).
