Insurance litigation firm Keoghs has reduced the amount
of
spam reaching its
network by more than 99% and has sped up the delivery of
business-critical e-mails through a Mimecast managed
service.
Mimecast's managed e-mail service was implemented as part of the
firm's
business continuity plan.
Keoghs had been using a system that merely placed potential
spam e-mails into a holding area, but these all had to be
reviewed and legitimate e-mails released.
"IT staff had to manually check about
6,000 potential spam e-mails a week, which delayed legitimate
e-mails and was a major drain on IT resources," said John Smith,
chief information officer at Keoghs.
Smith said that unlike most other systems, Mimecast does not
analyse content, but instead sorts e-mail based on a trusted-sender
list.
"This means less than 0.05% of spam needs to be reviewed, the
time e-mails spend in quarantine has been reduced from two hours a
day to a matter of minutes, and the issue of false positives and
genuine e-mails being blocked is practically eliminated," said
Smith.
Keoghs chose Mimecast on recommendation from integrator Network
Defence and several Mimecast users whom the law firm consulted, but
its quick and easy deployment as well as the fact that it has freed
up IT staff and improved the user experience made the choice a "no
brainer", said Smith.
