Cheap SSL certificates (eg the free SSL certificate issued by Let's Encrypt) have some disadvantages compared to more expensive ones.
Cheap SSL certificates do not allow extensive validation , which means that company details cannot be included in it. Therefore, your visitors will trust you less. And limited trust means limited sales, which is why webshops should avoid using cheap SSL certificates at all costs. An SSL certificate with extended validation guarantees at least 15% more sales.
A free SSL certificate such as those issued by Let's Encrypt is only suitable for a website . For file servers, applications, email, and the like, you need a paid SSL certificate.
You cannot use a proxy SSL certificate for all of your subdomains. So a premium certificate (such as one with extended validation) is recommended here as well.
With a cheap SSL certificate, you can't even add a Trust Seal to your checkout page. By adding their tag, your visitors will trust you more.
If you use a free SSL certificate, you will not receive any compensation in case of misuse.
