Zmail (also called ZSentry Mail) is the Mail module of ZSentry, offering cross-platform encrypted email capability. Zmail assures all parties that only authorized users can encrypt and decrypt messages. Zmail is an easy-to-use interface providing email security services for the software and email address that you already have, with unforgeable two factor authentication, anti-spoofing and anti-phishing, SSL SMTP and HTTPS service, 128-bit strong encryption, and an intuitive user interface.

You already know how to use ZSentry, all you need to do is press the button, we do the rest. There is NO download, NO installation process, NO plug-ins, NO digital certificates to buy or send, NO changes at all in your system. Zmail ends the encryption / decryption hassle that for more than 15 years has prevented the widespread use of email encryption.

Encrypt with 1-click™. You send encrypted zmail using your own desktop email application, or the zmail web interface just like Yahoo, MSN and Gmail webmail. Easy to send, even on first contact.

Decrypt with 1-click™. You receive zmail as a regular email message at your current email address at your desktop, webmail, or mobile device, using your current software and service, including Outlook, Mac Mail, Thunderbird, Eudora, or web mail services such as Gmail, AOL, and Yahoo.

Zmail is easy to read. This makes it also easy for you to decide sending a secure email, because you know that any recipient can read it without cost, installation, and (if you allow it) even without login or registration. You can send a secure email on first contact, to anyone.

Did you ever need to call to see if your email arrived? Do you think that someone could falsely claim that they did not receive your email, or say that they received it later than they actually did? Are you concerned about email phishing, email disclosure and identity theft? Are you concerned about your email confidential messages, password and keys being attacked and copied in someone else's —or even your own— "secure server"? Today, those problems are recognized as major sources of fraud losses and concern, posing significant challenges to anyone from individuals to large corporations. Those problems are solved by ZSentry Mail.

ZSentry has several modules. The workhorse module is Mail, which is used to provide ZSentry Mail (Zmail) services. Organizations can use zmail to protect their business information and also to protect their customers from phishing emails; health care organizations and professionals can use zmail to protect the confidentiality of private and health information in their email exchange; associations can use zmail to send secure ballots for their members to vote securely without paying postal mail; law firms can send electronic and scanned documents with zmail to cut down on FedEx costs and time. To track if their email was actually opened, when, where, and how, zmail users can easily request a return receipt as a condition for the recipient to decrypt their message. Zmail messages can be further controlled, with release date, expiration date, unforgeable digital signature, and other features.

Other ZSentry modules such as Billing, Payment, Sales, and Vault allow varied business processes, from lead generation to online sales and receiving payment, to be done securely in 1-click with your existing email solution, with no plug-in or download, and without requiring new investments.

The anti-phishing, mutual authentication, and two-factor authentication technology used in ZSentry was first qualified by the Swedish Government's Ministry of Justice Statskontoret in 2001. ZSentry does not store your keys, password and usercode anywhere, not even encrypted, so they are not at risk. With a proven anti-phishing solution, ZSentry prevents email fraud including spoofing and phishing. ZSentry also uses two-factor authentication to protect your password from someone trying to guess it. Your ZSentry message can self-destruct, after an expiration period set by you.Two-channel authentication can also be used, with one-time, unpredictable codes provided by OTP or cell phone SMS.

Only ZSentry has this comprehensive technology. Because only you have your keys, and it would take several ages of the Universe to have a good chance of guessing them, only you can access your encrypted email address book and decrypt zmails sent to you.

ZSentry Premium allows you to use ZSentry Desktop, which adds user-friendly, fast, email security to the desktop email solution that your organization already has.
