讓 Carmen 幫你判斷連結、簡訊或信件是不是詐騙
貼上簡訊、郵件、連結、電話號碼、截圖或公司名稱,一分鐘內取得風險結論、具體警訊與建議動作。
瀏覽網頁時同步檢查頁面,在你輸入密碼前警示仿冒或新註冊網域,並於裝置端遮蔽個人資訊。
審查進站郵件,辨識假發票、變更銀行帳號與高層冒充,並將可疑信件連同原因暫留待審。
篩檢陌生寄件者的簡訊,包括被手機過濾掉的訊息,評估其中的連結與付款要求是否符合典型詐騙手法。

為所有信箱攔截垃圾信、釣魚郵件與病毒的反垃圾服務
支援 iPhone、Android、Mac、PC、Office 365 與通用 IMAP/POP 帳號,一個過濾器即可保護讀取同一信箱的所有裝置。
每封新郵件在投遞前都會被分析,可疑寄件人、惡意連結與帶毒附件會被攔下,不會送到你面前。
每次你把郵件標記為垃圾或確認為正常,過濾器都會學習你的偏好,判斷越來越貼近你的需求。
被攔截的郵件不會遺失。你可以開啟 Spamdrain 帳號查看被攔內容,一鍵放行誤判郵件。
