Mimecast releases latest
Email Security Risk
Assessment (ESRA)
M
imecast Limited, a leading email
and data security company,
has announced the availability
of its latest quarterly Email Security Risk
Assessment (ESRA), an aggregated report
of tests that measure the efficacy of widely
used email security systems. A Mimecast
ESRA helps participating organisations
better understand the number and type
of email-borne threats that are getting
through their current defences. As part of
the cumulative assessments, Mimecast has
inspected more than 142 million emails
that have passed through organisations’
incumbent email security vendors. The
latest results revealed that 203,000
malicious links within 10,072,682 emails
were deemed safe by other security
systems, a ratio of one unstopped malicious
link for every 50 emails inspected.
13,176 emails containing dangerous file
types and 15,656 malware attachments
were all missed by these incumbent providers
and delivered to users’ inboxes.

“Our latest quarterly analysis saw a
continued attacker focus on impersonation
attacks quarter-on-quarter. These are
difficult attacks to identify without
specialised security capabilities and this
testing shows that commonly used systems
aren’t doing a good job catching them.”
The report indicates the need for
organisations to enhance their cyber-
resilience strategies for email with a multi-
layered approach that includes a third-party
service provider. This new ESRA report follows
an SE Labs Independent Email Security
Services Protection group test, which gave
Mimecast the top score and an ‘AAA’ rating.
“The SE Labs report highlights the need for
multiple layers of protection to increase
security efficacy and to address the
rise of more advanced email attacks,”
commented Gardiner.
The report also found an 80% increase
impersonation attacks in comparison to
last quarters’ report with 41,605 caught.
Additionally, 19,086,877 pieces of spam,

are still reaching employee inboxes. This
leaves organisations at risk of a data breach
and financial loss,” said Matthew Gardiner,
Cybersecurity Strategist at Mimecast.
Mimecast is engineered to use multiple
layers and types of detection engines,
combined with high-performance analytics
and a diverse set of threat intelligence
sources, overseen by the Mimecast SOC. This
helps protect email data and employees
from malware, spam, phishing and targeted
attacks – 100% from the cloud. n
