Why is it said that everyone should install an SSL certificate? The main reason is to improve the security of website data!

In the HTTP request process, there is no identity verification between the client and the server, and data is transmitted in plain text, exposed to potential hacker attacks on the internet, which cannot guarantee data security. This issue is precisely why SSL certificates were developed.

By installing a certificate, enterprises activate an “encrypted channel”—the SSL protocol—between the browser and the server to prevent data from being leaked or tampered with. When a website server has an SSL certificate, the URL in the browser will start with HTTPS, indicating to visitors that the site is protected by an SSL certificate.

Why must websites use SSL certificates?

1. Encrypt website data and protect website security: By installing an SSL certificate, HTTPS provides strong encryption of data, preventing user privacy data from being attacked by hackers during transmission. It helps prevent information leakage and impersonation by phishing sites, reducing unnecessary user loss and brand trust issues.

2. Increase visitor trust: Without SSL, users will encounter warnings such as “connection not secure” or “untrusted certificate” when visiting the site. Most users seeing these warnings will abandon the site or stop using the product.

3. Enhance company brand image and credibility: A high-quality company image can attract more users. Installing an SSL certificate makes your site stand out. Sites with SSL certificates display a green security padlock in the browser address bar, and if an EV SSL certificate is used, a green address bar and organization name will be displayed. This signals to users that the site is secure and trustworthy, encouraging safe operations and transactions, thereby improving the company’s brand image and credibility.

4. Achieve better search rankings: In early February 2018, Google’s Chrome browser announced a “ban” on HTTP sites. Using SSL certificates is an important SEO (search engine optimization) indicator. To improve traffic through natural search, it is recommended to use SSL certificates to enhance website security.

SSL certificates mainly come in three types: DV, OV, and EV, with increasing levels of encryption strength. For websites involving financial transactions, confidential information, or account passwords where high security is required, EV SSL certificates are the most suitable choice. SSL certificates have become a trend in internet security, playing a crucial role in data encryption and identity verification.
