PGP Universal Gateway Email
Strengths: An easy-to-use encryption gateway with excellent policy enforcement
Weaknesses: A bit expensive. Limited to policy-based encryption and digital signature protection
Verdict: Despite the higher cost for a software appliance, a valuable product
PGP Universal Gateway Email is a centrally managed email security software appliance, typically deployed on certified hardware devices. We installed the software using VMware ESX 3.5 and it is categorised mostly under the email security domain, as its goal is to handle encryption and signature duties via policy management.
Setting up the server was incredibly easy. The interface is one of our favourite. Upon login, those unfamiliar with PGP's product line will find the tutorials and policy diagrams very useful. The policy flow diagrams help you understand the flow of mail and how encryption is handled, based on types of clients, policies and other deciding factors.
The Universal Gateway protects email streams mostly between customers and outside contacts (internal mail is not typically secured). Although it is a pure-play email security gateway, it does inspect message content for keywords or sensitive content, in order to apply the appropriate encryption options.
The policies in place decide how to secure the email from a gateway perspective (SMTP, POP, IMAP), based on existing legacy clients, unauthenticated users, trusted sources etc. Workload is done at the server level, removing the need for client software and providing end-user transparency.
Disparate email clients, operating systems and recipient architectures are handled appropriately as well. End-users can receive encrypted emails if keys are available or delivery of a message can be pushed out via a PDF file or retrieved via web-based delivery on the gateway.
The ability to enter in 'learn mode', so PGP can learn about users and generate keys without actually performing any encryption, is also a nice touch.
Documentation is excellent. All of the help files, tool tips and tutorials are top-notch. The PGP website also has everything that customers need.
A silver level support package (24/5 phone, email and web support) is included for one year with the base licence. Renewal is £16 per seat/year and additional support tiers are available.
