管理您的安全性

地址欄中的掛鎖圖示和 HTTPS 不僅確保您資料的完整性,也增加了您的訪問者的信心,知道他們的個人和財務資訊是安全和加密的。除了滿足 HIPAA 和 PCI 的合規性要求,HTTPS 也是一個排名信號,有可能改善您網域名稱的 SEO。

在 Cloudflare 儀錶板點擊幾下滑鼠或通過 API ,即可輕鬆創建和管理您的 SSL 憑證。萬用字元憑證通過覆蓋域的多個級別,降低保護多個主機名稱的複雜性,例如example.com,.example.com,.secure.example.com), 全部使用同一個憑證。使您的 SSL 憑證保持最新是一項重要的安全實踐。Cloudflare專用 SSL 憑證在到期前會自動為您續期。當安全條件需要時,憑證也會自動重新頒發,以確保您的資料具有最高級別的完整性和可用性。

減少延遲並最佳化效能

憑證與訪客之間的實際距離越短,效能越高。Cloudflare 將您的憑證分發到我們遍佈全球的邊緣伺服器,大大減少了 TLS 交握期間產生的延遲。

Cloudflare 一直是 Transportation Layer Security (TLS) 1.3 通訊協定等新興加密技術的主要貢獻者。與先前版本的 TLS 相比,TLS 1.3 具有無與倫比的隱私性和效能,而 Cloudflare 是第一間在全球範圍內提供 TLS 1.3 的公司。現在,安全 Web 的效能比其他任何舊版和非安全 HTTP 更高。

此外,Cloudflare 還一直是全球實作 HTTP/2 和 Server Push 等網路技術的領導者,這些技術旨在改進網頁載入時間。要利用 HTTP/2 和 Server Push,必須透過 HTTPS 建立安全連線。


瀏覽器和裝置的最佳相容性

Cloudflare 簽發的憑證受到所有常見瀏覽器、電子郵件用戶端、作業系統和行動裝置的信任。

為了實現最大限度的相容,每個專用 SSL 憑證都包括三個憑證版本 SHA-2/ECDSA、SHA-2/RSA、SHA-1/RSA。當瀏覽器嘗試連線至您的網域時,Cloudflare 將提供最佳憑證版本來建立連線。

SHA-2/RSA 和 SHA-1/RSA 憑證利用 2048 位元的私密金鑰來保護資料傳輸,而 SHA-2/ECDSA 憑證使用 P-256 曲線。採用 ECDSA,不僅減小了金鑰大小,讓 TLS 變得更快速、更+可擴展,同時還可提供比 Web 上使用的預設加密更好的安全性。
