SSL Certificate


SSL certificates generally have three different levels of validation; Domain Validation (DV), Organization Validation (OV), and Endpoint Validation (EV). The key difference between these certificates is the information the GlobalSign Certificate Authority confirms to issue the certificate. Different information is displayed in the certificate and browser bar. For example, EV SSL turns the browser status bar green and displays the organization information directly in the browser bar.

Domain Validation (DV)
Suitable for small businesses or individuals, and will only check the domain owner's information on Whois. This type of certificate is easy and quick to obtain, and it will display a lock icon on the browser.
Organization Validation (OV)
Suitable for corporate websites or e-commerce sites, it will check the domain owner's information on Whois. And verify the organization before issuing the Certificate, with a certification issuance period of 2-4 days. The display on the Web Browser will show a green key in the Address Bar and the organization's name will appear in the Certificate details.
Extended Validation (EV)
Suitable for websites that require high organizational credibility, such as financial websites or medium to large corporate websites. The domain owner's information on Whois will be thoroughly and strictly verified before issuing the Certificate, with a certification issuance period of 7-15 days. This type of SSL Certificate provides the highest level of SSL security and is displayed on web browsers. A green key icon will appear in the Address Bar, covering the organization's name with a green bar.

Why do we need to use SSL (Security Socket Layer) Certificate? Nowadays, the reliability and security of accessing a website are very important. SSL Certificate is a secure and standardized data encryption technology for receiving and sending data through a website. Whether it is filling in personal information, credit card information, or making various transactions. The website that uses SSL Certificate will be a security certificate, which must be accessed through the website in https format to confirm the reliability and security of accessing the website.

Advantages of using SSL Certificate

In terms of Google Search Engine or Google Adword, Google will prioritize and give good SEO scores to websites that use SSL first. As a result, your website search via Google can be ranked higher easily. Importantly, in the past, using SSL required paying for an IP to be linked to SSL specifically. But now, it is not necessary to pay such expenses. Reduces the cost of using SSL Certificate By working through Server Name Indication (SNI), but SNI also has its limitations, namely It is not supported by old web browsers (If you use a web browser that does not support SNI and open the website, there will be a warning message as if your website does not have an SSL Certificate, but you will still be able to access the website).
