SSL 憑證是互聯網安全的基本因素。它們用於建立加密的連接，並允許在瀏覽器或用戶的計算機和服務器或網站之間安全地傳輸數據。
Choose DV for domain control validation, OV for organization validation, or EV for extensive organization identity checks. Validation level and hostname coverage are separate choices.
HTTPS is one part of a good website experience. It does not guarantee higher search rankings, and paying for a certificate or choosing a higher validation level does not establish an SEO advantage.
A correctly configured TLS certificate can help you:
不透過 HTTPS 提供的網頁現在在 谷歌瀏覽器 和 Mozilla Firefox中顯示為「不安全」。不要讓您的網站成為其中之一。立即添加 SSL。
Before ordering, confirm the hostnames, validation requirements, hosting environment, and who will install and maintain the certificate. Automatic deployment depends on supported hosting and configuration; it is not included for every environment.
For example, *.example.com covers shop.example.com and mail.example.com. Deeper names and unrelated domains need additional coverage; the root domain must also be included in the issued certificate.
Certificates must be installed on the relevant TLS services. Examples of hostnames you may need to cover include:
Confirm the names and services involved before choosing a certificate. Wildcard scope does not replace application security, access controls, or ongoing maintenance.

Where offered, a multi-year plan covers a purchased service period. Each issued certificate expires sooner, so certificates must be reissued and installed periodically during that coverage period.
Domain control and organization checks may need to be repeated. Certificate validity follows current certificate authority and browser requirements; the plan duration is not a promise that one certificate will remain valid for that entire period.
Before ordering, agree who handles validation, installation, reissues, expiry monitoring, and renewal. Automatic installation depends on the hosting environment and configuration.
Pricing tables show the price per year of coverage. The cart shows your chosen billing term and total payable. Available terms and warranty conditions depend on the selected product.
An SSL/TLS certificate supports encrypted connections between a browser and a server. HTTPS must be configured correctly; browser connection indicators vary.
HTTPS protects data in transit and helps a browser authenticate the server for the covered hostname. It does not establish that all site content is trustworthy or that applications and accounts are secure.
DV validates domain control. OV also verifies organization identity. EV requires extensive organization checks. These levels concern identity validation; they do not promise a different browser address-bar color or inherently stronger encryption.
A wildcard certificate covers matching hostnames at one subdomain level. The root domain must also be listed to be covered; deeper names and unrelated domains require additional coverage. 了解更多
EV certificates require extensive organization identity checks. They include verified identity information in the certificate details; modern browser presentation varies and a green address bar is not promised.
