Web security firm Sophoshas enhanced
its two e-mail appliances to prevent the outgoing leakage of
confidential information.
In addition to blocking e-mail-borne
malware, potentially unwanted applications and spam from
entering the corporate network via the e-mail gateway, the
appliances now enable businesses to scan outbound messages for
sensitive data.
They also use encryption to ensure the secure transit of
business critical e-mails.
New management controls included in the Sophos ES1000 and ES4000
e-mail appliances allow IT administrators to set and monitor user-
and group-specific policies that prevent e-mails containing
pre-defined keywords or strings of words from reaching unauthorised
recipients, both within and outside of the organisation.
The appliances can also identify and block confidential
attachments, including those that have had their file type
disguised by the sender.
These features, together with encryption, help organisations
comply with the raft of legal and regulatory requirements that
govern the security of confidential information, said Sophos.
