Microsoft Remote Desktop Service (RDP) is a very useful tool for administrators that need to login to remote Windows systems in order to perform administrative tasks or troubleshoot an issue. While incoming RDP connections from the Internet should be filtered by a firewall, this is not always the case.

A web "beacon" or "bug" is an element (usually a small, transparent image) found in an email that reports back to the sender that the message was opened by the recipient.

Most of the beacons and bugs aren’t hidden at all. Email senders can tell from any image in an email (even a logo) if a message was opened and if so, from where.

Microsoft Office 365 is gaining in popularity among organizations worldwide, regardless their size. This document focuses on the security features provided by Microsoft and why it is still essential for an organization to deploy the SECURE Email Gateway in front of the online version of Exchange.


ICAP stands for Internet Content Adaption Protocol and it is a protocol aimed at providing inspection for web content. An ICAP client routes HTTP content to an ICAP server in order to process it or adapt the content. The adapted content is then returned to the ICAP client in the form of an HTTP response or an HTTP request.

Clearswift SECURE Email Gateway can detect PGP encrypted messages. When a message contains a PGP encrypted attachment, it is not able to process it and the message is treated as Unknown Binary. Inter Engineering was able to extract common patterns in files encrypted with PGP or with the open source counterpart GnuPG (GPG).
