Like what the name has said, the SSL certificate is free, it does not have a price tag. The purpose of these free certificates is to make HTTPS available for all websites. with the secure connections.
Free SSL certificates come in 2 types, The Self-Signed Certificates are the ones without for any Certificate Authority to sign them. They are signed by the issuer him/herself. The second type of free SSL certificate available is signed by a Certificate Authorities in cPanel and Plesk. The encryption level is the time as the paid one.
A website with paid SSL certificates, you buy them. A paid SSL certificate is issued and signed by a trustworthy CA.
As far as the level of encryption is the same as the free SSL certificates. If you are wondering why should you buy an SSL certificate? Well, there are major differences between these two.
- Type of SSL Certificate
You can’t protect an organization with free SSL, while free SSL has only domain validation. If you need organization valuation or the extended validation which are offered in paid SSL.
The CA will validate and authenticates an OV or EV SSL certificate but the DV free SSL certificate. Visitors are able to view the organization details on the SSL certificate signed by the CA,
Free SSL certificates usually have a shorter validity period like 90 days while the paid SSL certificates can be as long as 24 months.
It is almost not possible to ask for re-issue or any support if you are using a free SSL certificate. Unlike, a paid SSL, most reputable CAs provide round-the-clock support using live chat and email.
A paid SSL certificate offers site seal and the options to choose it is OV or EV validated. This has greatly increased the confidant of your visitors, If you are selling things online, you gain trust.
A paid SSL certificate has a warranty from the CA, if anything goes wrong using this paid SSL, your losses are covered by the warrantied amount to its maximum value.
I will not recommend using the free SSL certificate. Actually, it has not only reflected the organization that it is less serious about her business but the trust is lesser. A free SSL certificate is only domain-validated. For an e-commerce website, I suggest Extended Validated and this is only available to a paid SSL certificate. The green bar which s unique to EV SSL certificate has increased greatly on the level of trust and authenticity.
