The intelligent software appliance for central e-mail security

The most frequent use of the Internet is to send e-mails. E-mails have established themselves as a standard part of the day's commercial traffic but, up to now it was not possible to represent all company-specific work processes involved in it electronically. The greatest challenge is to be able to securely exchange e-mail with confidential contents.

While it is possible to encrypt and sign confidential e-mails using e-mail clients, this requires staff to know how to use the security solution. As a consequence, the consistent implementation of a company's security policy depends directly on the knowledge and discipline of each individual member of its staff.

Utimaco's SafeGuard MailGateway integrates the cryptographic processes involved in encryption/decryption, and also in electronic signatures and verification, at one central point in the corporate network. The security solution is transparent for the sender and automatically implements the company's internal security guidelines for e-mail communication. The senders and recipients can communicate via e-mail in the usual way without having to worry about the confidentiality of the contents.

SafeGuard MailGateway guarantees:
That e-mail-based workflow processes are supplemented by confidentiality, authenticity and integrity in a simple and secure way

• A high degree of transparency for staff members, since the program can automatically decrypt and encrypt incoming, as well as outgoing, e-mails
• that e-mail encryption and digital signatures are implemented from a central location, so enabling the enforcement of internal security guidelines
• Simplified enforcement of internal security guidelines by integrating directory service information (e.g. Microsoft ActiveDirectory) into regulations
• Content-based email security through the simple integration of Data Leakage Prevention (DLP/ILP) systems

To encrypt or decrypt e-mails, and make digital signatures, SafeGuard MailGateway uses the established S/MIME and OpenPGP Internet standards. Alternatively, SafeGuard PrivateCrypto and SafeGuard WebMail ensure that connections between external communications partners are secured, without a security infrastructure.

The Utimaco innovation SafeGuard PDFMail automatically encapsulates an e-mail, along with its attachments, into an encrypted PDF file, allowing the recipient to securely respond to the e-mail. The encrypted PDF document can then be sent in an e-mail to its recipient, thus securing the safe transmission of confidential information.

The recipient merely requires a conventional PDF reader and the corresponding password in order to decrypt the PDF document and to read the confidential content of the e-mail. The attachments contained in the PDF document retain their original format (e.g. .doc, .xls, .ppt), and can be extracted and modified. The recipient can afterwards return an encrypted reply using the integrated reply function, as well as include attachments to his reply.

SafeGuard MailGateway is scalable from small installations through redundant installations to organization-wide use in clusters.
