Which SSL certificate to choose for corporate website







Domain Verification Certificate (DV)
It is ensured that the transmission of confidential information of the website from the user's browser to the server is high-strength encrypted transmission, and will not be illegally stolen and illegally tampered with. You only need to prove that the domain name you want to protect is owned by you, and you can pass the certification authority (CA) audit. The issuance speed of domain name verification is fast, but because almost everyone can get the issuance of the DV certificate, the trust level is low.

Organizational Validation Certificate (OV)
It is a more advanced and better SSL certificate that needs to verify the true identity of all organizations on the website. It is different from the domain name verification (DV) certificate in that it requires some additional review work to ensure that you not only own your own domain name, but also that your company and organization are legal. Organizational Verification (OV) can not only encrypt the confidential information of the website, but also prove the true identity of the website to users.

Extended Validation Certificate (EV)
It refers to a certificate that needs to pass the high-level identity audit of an enterprise or unit to be issued. The certification authority will verify the authenticity of the applicant’s unit name, address, telephone number, bank account and other information. It usually takes 2-5 working days to review the information. The extended verification certificate has the highest level of encryption security. It is displayed in the browser address bar. Display the names of companies and units to facilitate users to identify fake websites.
