Website – the first means for customers to evaluate the reputation and professionalism of the business they are interested in. Therefore, a website is essential for businesses regardless of the size of the company, large or small, doing business or not through the website. Previously, many businesses focused on building attractive websites and ensuring full content for customers. However, recently, businesses have begun to learn about SSL – the global technology security standard for websites after Google began to issue warnings for websites that do not possess this security certificate.
Therefore, in this article, GLA provides detailed information about SSL certificates to help businesses better understand and how to register for SSL security certificates for websites.
1. SSL security certificate concept
SSL - Secure Sockets Layer, a global security technology standard used for encrypted communication between a web server and a browser. This standard works and ensures the security of all data transmitted between the server and the user's browser.
Currently, most websites around the world are installed with SSL to enhance the security of data transmitted over the internet environment.
In other words, when installing an SSL certificate on a business's web server, customers' sensitive information (e.g. email accounts, credit card numbers and usernames, etc.) when accessing the website will be encrypted and avoid the risk of information theft from those who want to steal the user's identity.
Therefore, when owning a website with an SSL certificate, customers will feel secure when providing personal information on the website and the business will have increased credibility with customers.
SSL security certificates have two functions:
- Authenticate the identity of the website (this assures visitors that they are not on a fake website
- Encrypt the data being transmitted.
2. Classification of SSL security certificates
2.1. Domain Validation (DV - SSL)
DV - SSL certificate authenticates the website's Domain Name and activates the "green lock" which means the website is securely encrypted when exchanging data.
DV – SSL certificates are suitable for individual customers or small and medium-sized businesses with standard encryption needs and low registration costs.
2.2. Organization Validation (OV - SSL)
OV - SSL certificate authenticates the website and verifies the business that owns the website. Besides activating the "green lock" for the website.
2.3. Extended Validation (EV -SSL)
EV - SSL certificate authenticates the website with the highest level of security and is legally reviewed. In addition, the address bar turns green and displays full business information.
2.4. Wildcard SSL Certificate
When adding Wildcard SSL, the SSL certificate will secure all sub-domains of the website. Therefore, Wildcard SSL is suitable for businesses providing e-commerce services because the business can create multiple e-store pages from the main website, each e-store is a sub-domain and is shared on a single IP address.
In other words, with just one single SSL certificate with additional Wildcard, a business can run unlimited sub domains of that website.
2.5. SANS SSL
A standard SSL certificate only secures a single verified domain name. Therefore, for websites with multiple domains, businesses can add SANs (Subject Alternative Names) – multiple domain names combined into one security certificate.
In particular, SANs have higher security for data exchanged between customers and web servers than Wildcard SSL.

1. What is TLS? Do businesses need to register for TLS?
TLS (Transport Layer Security) is an upgraded and more secure version of SSL. Nowadays, the term TLS is often used instead of SSL because of its popularity.
HTTPS works on top of TLS encryption built into the HTTP protocol, which is implemented by most websites and web services. So any website that uses HTTPS uses TLS encryption.
When a business registers SSL, the website will always use TLS.
2. How to earn money for a website that already has an SSL certificate?
To determine if a website uses SSL encryption, you can:
Check the URL: If it starts with "https://" instead of "http://", the site is encrypted.
Look for the lock icon in the address bar.
Click the lock icon to view certificate details and signing date.
