In today's digital age, securing personal information and data on the Internet is becoming a matter of life and death for any business that owns a website. One of the important technologies that helps protect data effectively is the SSL (Secure Sockets Layer) certificate.
So what is SSL? Is it really necessary to install SSL for a website? And what are the practical benefits of SSL in business?
Let's explore the details in the article below with MIMA TRADING AND SERVICE CO., LTD!
What is SSL?
SSL (Secure Sockets Layer) is a data encryption protocol between the user's browser and the website hosting server. When a website has SSL installed, data is encrypted before being transmitted, thereby preventing the risk of information being stolen by hackers, spyware or intermediaries.
Currently, SSL has been inherited and upgraded to the TLS (Transport Layer Security) standard. However, the concept of "SSL" is still commonly used to refer to website security certificates.
What does a website with SSL look like?
You can recognize a website with SSL by the following 2 signs:
- The browser displays a green padlock or security icon next to the domain name.
- The website address starts with https:// instead of just http://.
For example:
❌ http://mimadigi.com → Not Secure
✅ https://mimadigi.com → Secure, SSL certificate installed
Why does a website need an SSL certificate?
User data security:
- When users fill in information (phone number, email, password, bank card information...) on a website without SSL, the data may be eavesdropped on or changed during transmission.
- SSL helps encrypt this data, only the correct recipient can decrypt it, avoiding Man-in-the-middle (MITM) attacks.
Increase credibility and professionalism: Websites without SSL are often warned by browsers as “Not Secure”, making customers doubt their reliability. In contrast, a website with a security padlock shows professionalism and customer care.
Increase SEO ranking on Google: Since 2014, Google has confirmed that SSL is a ranking factor in its search algorithm. That means: Websites with SSL will be prioritized over unsecured websites, especially in highly competitive fields such as e-commerce, services, education...
Required for websites selling goods and online payments: Payment gateways such as VNPay, Momo, ZaloPay, PayPal... require integrated websites to have SSL. Without SSL, you cannot connect to online payments.
Prevent phishing attacks: SSL helps customers know that they are accessing the correct official website, not a fake website created to commit fraud and steal data.
What types of SSL certificates are there?
Depending on the needs and scale of the website, SSL is divided into 3 main types:
Domain Validation SSL (DV-SSL)
✅ Simple domain verification.
✅ Fast installation time (5 – 10 minutes).
✅ Suitable for personal blogs, landing pages, introduction websites.
Organization Validation SSL (OV-SSL)
✅ Verify both the domain name and the owning business.
✅ Shows business information on the certificate.
✅ Suitable for company websites, service websites.
Extended Validation SSL (EV-SSL)
✅ Highest level of verification.
✅ Clearly displays the business name on the browser bar.
✅ Suitable for banks, payment gateways, large e-commerce sites.
Free SSL and Paid SSL: Which should I choose?
Free SSL (Let’s Encrypt)
✅ Suitable for small websites, personal blogs.
✅ Automatically renews (if configured correctly).
❌ Does not support warranty or business verification.
Paid SSL
✅ Technical support, brand verification, warranty from the publisher (from $10,000 - $1,000,000 depending on the type).
✅ Suitable for company websites, e-commerce websites, websites containing user data.
💡 Advice from MIMA: If you are running a sales website, introducing your business, or have payment integration, prioritize paid SSL to ensure the best reliability and support.
