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。
Standard SSL (Domain Validated) Certificates are the easiest and most common type of SSL certificate. OV and EV Certificates also authenticate the identity of the company or organization that holds the certificate providing more trust to end users.
With our SSL certificate services*, you won't need to take manual steps to configure and deploy new certificates every year. We generate a renewal order automatically when your certificate nears the end of its validity. After payment, we will automatically configure, validate, and provision your new certificate for you.
* Your domain must be hosted through the same hosting provider who sold the SSL certificate, and the server must use cPanel, Plesk, or DirectAdmin.
為您的網站訪客和業務建立信任和在線安全性。
Google 希望使網絡更安全，其中一大部分涉及確保人們通過 Google 訪問的網站是安全的。這就是為什麼使用 SSL 的網站在搜索結果中獲得更高的排名中受益的原因。
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。
雖然對線上安全的需求是普遍的，但並非所有 SSL 憑證都是一樣的。以下指南旨在幫助您決定哪種類型的憑證適合您。
非重要網頁的理想選擇
想像 DV 就像獲得圖書館卡一樣 —— 沒有確認您的真正是誰，要求很少要求才能快速獲得和發行。
非常適合更敏感的網頁，例如登錄頁面
想像 OV 就像獲得駕駛執照一樣 —— 比圖書卡更可以通過，但作為身份識別的形式更值得信賴。
非常適合敏感網頁，包括電子商務，網上銀行，帳戶註冊
比使用圖書館卡或駕照，比使用圖書館卡或駕駛執照，電動車就像獲得護照一樣，流程更嚴格，交貨時間更長，以及對您的身份驗證更多。被國際認可為驗證您的身份最值得信賴的方式。
