What is PGP Desktop Email and why is it important?
PGP Desktop Email is an innovative desktop email encryption solution that automatically encrypts email based on policy using open standards. PGP Desktop Email operates as a proxy, removing the need for application- and version-specific plugins, increasing performance, and eliminating potential email application conflicts or incompatibilities.
PGP Desktop Email encrypts email as it is received and sent without affecting the end-user email experience. PGP Desktop Email secures data sent in email from unauthorized access, including administrators with access to the mail server data store.
What business problem does PGP Desktop Email solve?
Email sent to and from an organization can contain the most sensitive customer, patient, financial, or intellect property data. PGP Desktop Email allows organizations to meet audit and compliance requirements while securing their brand. Because PGP Desktop Email does not affect the end-user email experience, it does not impact productivity.
What are the key benefits of PGP Desktop Email?
PGP Desktop Email provides organizations with the following benefits:
- Enforce email security policies: Used in combination with PGP Universal Server, PGP Desktop Email automatically secures email messages based on centrally defined email encryption policies.
- Reduce operational costs, accelerate deployment: By operating in the background and securing messages according to policy, PGP Desktop Email can be quickly deployed without the need for special user training or increased help desk load. As a PGP Encryption Platform–enabled application, PGP Desktop Email can share policies across groups and quickly tailor them, allowing administrators to deploy PGP Desktop Email and focus on other projects.
How does the PGP Desk Email work?
PGP Desktop Email operates as a local, desktop mail proxy service, automatically encrypting/decrypting messages according to policy. PGP Desktop Email supports the two global email encryption standards, OpenPGP and S/MIME, automatically discovering keys and certificates. When centrally managed by PGP Universal Server, PGP Desktop Email's key management, policy, and software updates are managed by PGP Universal Server.
What is the end-user experience?
For end users, PGP Desktop Email operates in the background, processing email messages based on policy. If allowed by policy (or if not managed by PGP Universal Server), end users can adapt email encryption policies and change configuration through the PGP Desktop Email application interface. When encryption or digital signature operations are performed, PGP Desktop Email’s notifier window alerts users that an operation is being performed and its status.
