Introduction

This Administrator’s Guide describes both the PGP Universal Server

™

and PGP

Universal Satellite. It tells you how to get them up and running on your network,

how to configure them, and how to maintain them. This section provides a high-

level overview of PGP Universal Server.

What is PGP Universal Server?

PGP Universal Server provides multiple encryption solutions managed from a

single console.

PGP Universal Server with PGP Universal Gateway Email gives you secure

messaging: it transparently protects your enterprise messages with little or no

user interaction.

The PGP Universal Server also replaces the PGP Keyserver product with a built-

in keyserver, and the PGP Admin product with PGP Desktop configuration and

deployment capabilities.

It automatically creates and maintains a Self-Managing Security Architecture

(SMSA) by monitoring authenticated users and their email traffic. You can also

send protected messages to addresses that are not part of the SMSA. The PGP

Universal Server encrypts, decrypts, signs, and verifies messages automatically,

providing strong security through policies you control.

15

PGP Universal Server Introduction

PGP Universal Satellite, a client-side feature of PGP Universal Server, extends

PGP security for email messages all the way to the computer of the email user,

it allows external users to become part of the SMSA, and it gives end users the

option to create and manage their keys on their own computer (if allowed by

the PGP administrator).

PGP Universal Server Product Family

PGP Universal Server functions as a management console for a variety of

encryption solutions. You can purchase any of the PGP Desktop applications or

bundles and use PGP Universal Server to create and manage client installations.

You can also purchase a license that enables PGP Gateway Email to encrypt

email in the mailstream.

The PGP Universal Server can manage any combination of PGP encryption

applications. PGP encryption applications are:

 PGP Universal Gateway Email provides automatic email encryption in the

gateway, based on centralized mail policy. This product requires

administration by the PGP Universal Server.

 PGP Desktop Email provides encryption at the desktop for mail, files, and

AOL Instant Messenger traffic. This product can be managed by the PGP

Universal Server.

 PGP Whole Disk Encryption provides encryption at the desktop for an

entire disk. This product can be managed by the PGP Universal Server.

 PGP NetShare provides transparent file encryption and sharing among

desktops. This product can be managed by the PGP Universal Server.

Who Should Read This Guide

This Administrator’s Guide is for the person or persons who implement and

maintain your organization’s PGP Universal Server environment. These are the

PGP administrators.

This guide is also intended for anyone else who wants to learn about how PGP

Universal Server works.
