Virtru:線上郵件加密服務平臺由前 NSA 的安全技術人員 Will Ackerly 創立的，提供郵件加密服務，目前它支援 Gmail 和 Outlook 等郵件服務，幫助使用者解決因郵件洩密而引起的網路安全。

使用方法很簡單隻要裝好一 Chrome 外掛並在諸如 Gmail 等郵件服務啟用，在傳送郵件時就能用 Virtru 給郵件加密，並對郵件內容做額外安全限制，比如禁止轉發和設定內容過期時間。沒有裝 Virtru 的收件人可直接通過點選鏈入 Virtru 來線上瀏覽郵件內容。

一方面是網路承載的個人資料越來越多，另一方面是資訊洩露案例也在變多。普通公眾的資訊保安意識也在覺醒。這也使得資訊保安不再是企業級市場的需求了，個人消費領域也有很大空間。
