Mimecast report: legacy email security
systems failing to provide sufficient
security protection
Mimecast’s latest
quarterly Email Security
Risk Assessment (ERSA)
has revealed thousands
of known malware and
impersonation attacks
are getting past systems
meant to protect
organisations.
E
mail is an integral part of daily
operations for most organisations,
so it is important to ensure there are
effective security strategies in place to
manage these systems.
Mimecast Limited, a leading email and
data security company, has announced the
availability of its quarterly Email Security
Risk Assessment (ESRA), a report of tests
that measure the effectiveness of incumbent
email security systems.
This quarter’s assessment reports that these
systems missed 11,653 emails containing
known malware, which should be the
easiest to identify as they are detectable by
commonly deployed endpoint-based anti-
virus technologies.
Additionally, the report noted a continued
challenge of securing organisations from
unknown malicious attachments, dangerous
file types, impersonation attacks and even
basic spam.
As part of the assessment, Mimecast
inspected more than 95 million emails, all
of which had passed through organisations’
incumbent email security vendors. These
organisations, in 20 different industries,
invested millions of dollars to deploy a
variety of commonly used on-premise and
hybrid email security systems.

The latest report found more than
14,277,163 pieces of spam, 9,992 emails
containing dangerous file types and 849
unknown emails with malware attachments
were all missed by the incumbent providers
and delivered to users’ inboxes.
Most notably, 11,653 known emails with
malicious attachments passed through these
systems, an increase of 532% in comparison
to last quarter’s assessment.
Impersonation attacks also continue to
be a problem for organisations as 23,072
were caught, increasing 22% in comparison
quarter over quarter. The report indicates
the need for organisations to enhance their
cyber resilience strategies for email.
