SSL Certificates can be divided into two types: free and paid. Considering the security level, many people will choose to charge SSL Certificates instead of free ssl certificate. So, what are the disadvantages of free SSL Certificates? Where is it embodied? Today's small series will come down.

What are the disadvantages of Free SSL Certificates?

Free SSL Certificates are available, but it is not recommended that you use free SSL Certificates. Because one is likely not to be trusted by major browsers, and the other is that the level of security protection is not enough to truly protect the website.

The so-called free SSL Certificates on the market are basically domain name type, enterprise type is paid. CA agencies set the validity period, from the security point of view, can not guarantee that a legitimate website will never become a phishing site, CA agencies need regular audits, will not issue a permanent valid certificate.

Free domain name certificate, need to re-apply before expiration, may fail security audit. Of course, there are many other reasons why certification fails.

Because domain name SSL Certificates are issued quickly through automatic authentication, manual intervention in auditing will not be required, and stricter sensitive words will be used to strengthen auditing standards.

SSL Certificates are a security protocol designed to provide security and data integrity for Internet communications. SSL Certificates follow SSL protocol and can be installed on servers to encrypt data transmission. In fact, it is the certification of the user's public key by the CA institution, including the information of the electronic visa authority, the public key user information, the signature and validity period of the authority, etc.

Therefore, if users really want to ensure the security of website information, free SSL Certificates are not reliable, or recommend the use of normal fees certificate

What is the difference between free SSL Certificates and paid ssl certificate

I. Certification type

SSL Certificates are completely free only DV SSL Certificates, while Paying SSL Certificates not only DV SSL Certificates, but also OV SSL Certificates and EV SSL Certificates.

Completely free SSL Certificates only have to authenticate domain name registration and nothing else, so there is a big security risk. After all, today's network hackers only need to authenticate domain name information to be able to successfully obtain the content of certificate information, and then put on a reliable coat for themselves. At this time, https still has the effect of encrypted transmission, but the destination of information content transmission has changed from the network server of the real website to the "fishing" network server of the network hacker. The data encryption is also like a dummy, and the network hacker crawls the sensitive information content of the customer more and more effortlessly.

II. Application limits

Free SSL Certificates are associated with only 1 domain name registration and are incompatible with wildcard domain name registration and multi-domain name registration. At this time, the relevant service items will also be greatly discounted. Most of the completely free SSL Certificates are installed by the customers themselves, and there is no way to show the middle and late service items and service support. When encountering the installation problems of SSL Certificates, there is no way to get them handled.

Shops who show paid SSL Certificates usually show a series of browsing from declaration to installation, and then there are problems, and they also look for service providers to deal with.

III. Application time

Free SSL Certificates have a relatively short validity period, about every 3 months or January to upgrade, after the expiration of their own declaration, many customers will easily forget to renew.

The application period of paid SSL Certificates is usually 2 years, so there is no need to worry about the expiration of certificates at all times.

IV. Selection of diversity

At this stage, it is completely free to show SSL Certificates such as Lets Encrypt, Comodo, etc., while paying for SSL Certificates is much more selective, Comodo, GeoTrust, Symantec, RapidSSL and other famous CA organizations.

To sum up, free ssl certificate, suitable for personal websites, relative to large enterprises or personal web pages with higher total traffic or choose paid SSL Certificates as good, after all, free ssl certificate shortcomings or many.
