ZSentry customers can easily enable people to send back a free, immediate, secure, first-contact, message or reply. Works with the user's IT solutions without setup on the desktop, tablet and phone.

How does it work?
The user clicks the button  Secure Quick Reply 

That's all! The service is provided without burdening the recipient with anything more than a mouse click. Just like with regular email, there is no password to send to the recipient, no signup, cost, installation, setup, or extra work demands. Recipients can use any desktop, tablet or phone.

Senders can select how the recipient must be authenticated, allowing the message to be securely decrypted for reading and reply. The reply data is encrypted before transmission, and ZSentry creates a securely encoded message back to the original sender.

How can recipients use this service?
Just by receiving a "starter" ZSentry mail, sent to the recipient's regular email address (any provider).

For example, you send ZSentry mails to your customers with expired credit cards, asking them to reply securely with updated information. The secure email you send has no privacy concerns but is your customer's "ticket" to send back the secure information you want. Or, you call your doctor's office and give them your regular email address, asking them to send you a ZSentry mail starter. That secure email should have no privacy concerns but is your "ticket" to send back the secure information you want.

How can a recipient send a free secure reply?
To reply with private information, you click the button  Secure Quick Reply 

How can a recipient send a free secure message?
To send private information, you click the button  Secure Quick Reply 

Can recipients send back attachments?
Yes, if the sender enables it.

How is the information protected?
The information you send will be protected by encryption before sending, it is encrypted per message, requires the recipient's positive identity confirmation according to the sender's choice (see "How is the service controlled?"), and can be read only after the recipient's device and mailbox authentication, and is assured using multiple, independent cryptographic means.

Senders can use a number of security options available for customers, such as requiring recipient login, requesting a Secure Vault copy (requires the sender's login to read) for regulatory compliance with message archiving, and a Return Receipt that sends back to the sender information on When, Where, How, and Who read the message, every time that it is read. Senders can also set the message to Self-Destruct (the default is 15 days), to define the time allowed to use the message and take control (technically and legally) when the information can be used.

How is the information that the recipient sends back protected?
The information sent back by the recipient will be protected by encryption before sending and encrypted per message, encoded only to the original sender. It will require the original sender's positive identity confirmation for reading, and can be read only after device and mailbox authentication, assured using multiple, independent cryptographic means.

The recipient can also easily set her own sender choices, such as requesting a Secure Vault copy for herself (will require signup and login to read), and a Return Receipt that sends back to the original recipient the information on When, Where, How, and Who read her message, every time that it is read. She can also set her message to Self-Destruct (the default is 15 days), to reduce the time allowed to use the message.

How is the service controlled?
The are two choices: Free Reply and Free Reply With Login, selected by the sender.

Free Reply is the default ZSentry sender choice, and does not require the recipient to register or login. This is the most usable choice for recipients, when sending secure email. It provides challenge-response device and mailbox authentication, login monitoring, and expiration control. Recipients can read and reply securely to the sender, but cannot use ZSentry to forward or reply to anyone else. Recipients can also use customer support.

Free Reply With Login is the alternative choice. It is selected when a ZSentry sender requires recipient signup, or also login. Recipient signup and login are provided free of charge, and are controlled by ZSentry without burdening recipients or the sender in providing passwords for recipients or pre-enrolling recipients. This choice enables recipients to send back attachments, read their own Secure Vault files of email that they sent, use password reset 24/7, and use customer support.

Why is it free?
What are the most valuable emails for your organization? The emails that you receive. With ZSentry, you can make them secure, regulatory compliant, and free to send.

Also, for a number of reasons including cost and management, it is usually not viable to include customers, partners, providers, and suppliers in a secure email account provided by an enterprise. This issue is becoming more important with BYOD ("bring your own device") and the consumerization of the enterprise. However, there are regulatory and security needs for enterprises to communicate securely beyond the enterprise borders, with practically anyone and often on first contact.

As another example, doctors tell us that they would like to strengthen their physician-patient relationship. Email can help, like few things could, with a secure "Free Patient-to-Physician Email". And patients actually want to email their doctors. A health care provider, however, is a Covered Entity under HIPAA and has a legal duty to comply with privacy regulations and protect the patient's health information.

Regulatory compliance is a mandatory business need and not only in the health-care sector. Businesses and government entities in general must not allow user data to be disclosed, and should not create a cost or work burden for regulatory compliance, and yet need to communicate with users, including sending and receiving data.

The ZSentry Free Reply services satisfy these needs, helping assure regulatory compliance for the enterprise with zero cost and no burden for recipients.

What if a patient wants to email her doctor concerning treatment?
Patients may initiate communications with a health care provider using email, according to HIPAA. However, providers may have concerns about potential liability under the HIPAA Privacy Rule [see 45 C.F.R. § 164.530(c)], including their determination whether a patient is aware of the possible risks of using unencrypted email.

These concerns do not apply when ZSentry is used to provide secure email, which is regulation-compliant in sending information to the customer, is free and easy to use by the customer to read and reply, and protects information sent back by the customer.

What are the terms of service?
Services are authorized by ZSentry Premium users and are regulated by the ZSentry Basic Terms of Service.
