Today, Internet users are getting more & more aware of their website, databases & information’s security needs.

That is why SSL is regarded as the bridge between the browser and server.

As the number of data breaches, cyber-attacks and malware attacks are increasing day by day, use of SSL certificate has become a must. Not only the e-commerce stores, but other parties such as social media networks, banks, Governments, small/medium level businesses also need SSL Certificates to secure their user’s private information. There are mainly 3 types of SSL certificates available in the market today.

Different Types of SSL Certificates


Extended Validated (EV) SSL Certificate

EV SSL Certificate is the most recommended SSL type as it displays green address bar along with the business name in URL which indicates the legitimacy of the business and ensures the users that the information being shared by them is not accessible by others. It delivers robust encryption up to 256-bit which boosts user’s trust and confidence in the website.

To issues an EV SSL certificate, the issuer need to submit important business documents as per the certificate authority’s requirement. It takes up to 10 days to issue an EV SSL Certificate. Read our EV SSL certificate document requirement guideline for more information.

Organization Validated (OV) SSL Certificate

Organization validated SSL is highly recommended to validate online business. It delivers up to 256-bit encryption length and is supported by 99.9% web and mobile browsers. Business name is displayed in certificate and a CA’s seal, which is considered to be a trust indicator.

To issue an organization validated SSL certificate, the user/organization needs to submit business documents as per the requirement of certificate authority (CA). It takes up to 3 days to issue an OV SSL. Read our OV SSL Certificate document guide for more information.

Domain Validated (DV) SSL Certificate

Domain validated SSL certificate is used to validate the domain name only. If a user carries a small/medium level website, DV SSL certificate is the best option. Like OV & EV SSL, a DV SSL certificate can also deliver up to 256-bit encryption strength. The validation process for the domain validated (DV) certificate is pretty simple.
