Comodo SecureEmail

Why Use SecureEmail Email Security Software?

Unencrypted, plain-text emails can easily be intercepted, read, and edited. In fact, sending an unencrypted email is a bit like sending a postcard written in pencil: whoever intercepts it can read it with ease. Until now, the process of encrypting email messages was lengthy, difficult, and cumbersome, even to the most tech-savvy PC user. Of course, security systems that, however necessary, are a chore to use will never be adopted on a large scale. That's why we created SecureEmail: it's total secure email without the hassle. Unlike conventional email security software, we make it easy.

SecureEmail Features

• Just install and forget! SecureEmail automatically encrypts all emails and manages the certificate exchange process
• Install as a seamless Plug-in to Microsoft Outlook or in Network Level Mode for compatibility with most other mail clients
• Innovative one-time 'session' certificates allow encrypting email without first exchanging signed mails
• Built-in wizard allows quick download and installation of Comodo email certificates

In the past, exchanging digital signatures with someone required both of you to send each other already signed secure emails. Before taking this step, neither could read each other's encrypted secure emails. SecureEmail's unique ‘session' certificates make this usually complex process seamless. Here's how it works: when sending a digitally signed secure email to someone else, they'll be able to view it immediately by either downloading SecureEmail themselves, or simply using our online WebReader.

Frequently Asked Questions about SecureEmail Email Security Software

Which e-mail clients does SecureEmail support?

SecureEmail is confirmed to support Outlook 2000 and above, Outlook Express 5.5 and above, Thunderbird 1.5 and above, Windows Mail, Incredimail, Windows Live Mail, and Eudora.

Does SecureEmail work with POP/SMTP mail clients other than Outlook, Outlook Express, Thunderbird and Incredimail?

It should work with most Windows mail clients that use POP, SMTP or IMAP protocols, but testing has not been completed, and you may experience unexpected behavior. Check out our forums for more.

Installation modes - What's the difference between Outlook mode and Network Level Mode?

Both modes feature the same core functionality and feature list. However, there are differences:

Outlook Mode - CSE is installed at the 'software layer' as a tightly integrated plug-in to Microsoft Outlook. This mode is highly recommended for Outlook users and will install the SecureEmail Toolbar into the Outlook interface. The Toolbar provides a fast and easy way to configure Comodo SecureEmail without leaving Outlook.

Network Level Mode - CSE is installed at the network level and is therefore not 'tied' to any particular client - it will intercept and handle all mail traffic coming into or out of your system regardless of the client you are using. This mode is recommended for non-Outlook users and has the advantage of being able to provide encryption capabilities even to mail clients that do not support encryption.

What are single-use certificates?

Single-use certificates are one-time 'session' certificates that enable the encryption protection of messages to recipients when you do not have their 'regular' secure email certificate installed on your system.

Will my port settings be imported into SecureEmail?

Yes. SecureEmail will automatically import your port settings from previously configured mail accounts in Outlook, Outlook Express and Thunderbird.

I already have an e-mail certificate from a vendor other than Comodo CA. Will SecureEmail work with my certificate?

Yes, but with certain qualifications. You must use a Comodo email certificate to digitally sign your mail but you can choose to use a 3rd party email certificate to encrypt and decrypt your mail. This means that you can continue sending/receiving encrypted mail with existing contacts without any interruption.

How do I get a free Comodo certificate?

You can either use the Sign-Up Wizard on the Certificates tab on the SecureEmail main window, or sign up for one at our website.

Do I have to disable encryption and signing (S/MIME) in my e-mail client?

In Network Level Mode, yes. For smooth operation of the software, it is strongly recommended that you turn off signing and encryption in your e-mail client. Both of these duties will be performed by SecureEmail instead.

In Outlook Plug-in Mode, no - you don't have to disable encryption and signing.

Why are some mails not signed in Network Level Mode?

This could be because your e-mail client has encrypted an e-mail before SecureEmail intercepted it. Please ensure that encryption and signing have been turned off in your e-mail client.

Why isn't the SecureEmail auto decryption footer added to some decrypted e-mails?

This is probably because the e-mail was also signed. Adding extra data to a signed e-mail would destroy the integrity of the e-mail's signature, making the signature invalid.

Where does SecureEmail store my certificate and my contacts' certificates?

SecureEmail uses the standard Microsoft Windows certificate store on your computer to store certificates. You can view these from the Certificates tab in the SecureEmail main window.
