Mimecast<\/a><\/strong>, a leading email and data security company, announced the availability of its quarterly Email Security Risk Assessment (ESRA), a report of tests that measure the effectiveness of incumbent email security systems.<\/p>\n

This quarter\u2019s 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.<\/p>\n

Additionally, the report noted a continued challenge of securing organisations from unknown malicious attachments, dangerous files types, impersonation attacks, as well as even basic spam.<\/p>\n

Key findings of the report<\/strong><\/h3>\n

As part of the assessment, Mimecast inspected more than 95 million emails, all of which had passed through organisations\u2019 incumbent email security vendors.<\/p>\n

These organisations, in 20 different industries, invested millions of dollars to deploy a variety of commonly used on-premise and hybrid email security systems.<\/p>\n

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 — all missed by the incumbent providers and delivered to users\u2019 inboxes.<\/p>\n

Most notably, 11,653 known emails with malicious attachments passed through these systems, an increase of 532 percent in comparison to last quarter\u2019s assessment.<\/p>\n

Impersonation attacks also continue to be a problem for organisation, as 23,072 were caught \u2013 increasing 22 percent in comparison quarter over quarter.<\/p>\n

A need for enhanced cyber resilience strategies for email<\/strong><\/h3>\n

The report indicates the need for organisations to enhance their cyber resilience strategies for email.<\/p>\n

\u201cMimecast\u2019s ESRA is aiming to establish a standard of transparency that raises the bar for all security vendors helping organisations pinpoint weaknesses in their defenses,\u201d said Matthew Gardiner, cybersecurity strategist at Mimecast.<\/p>\n

\u201cEmails ranging from opportunistic spam, targeted impersonation attacks and unknown malware are getting through incumbent email security systems. The security system of one primary cloud email platform missed 76.6 percent of the aggregate impersonation attacks while another global security vendor missed the 83.4 percent of the \u201cknown\u201d malware attachments.\u201d<\/p>\n

Vanson Bourne cybersecurity research<\/strong><\/h3>\n

Mimecast recently conducted global research with Vanson Bourne on the state of organisations\u2019 cybersecurity, what attacks they\u2019ve seen increase, and their level of confidence to thwart these evolving attacks.<\/p>\n

The findings were based on responses from 800 IT decision makers and C-level executives.<\/p>\n

Not surprisingly, and consistent with the results of the Mimecast ESRA report, organisations are forecasting a challenging future, with nearly 60 percent of respondents having said their organisation is likely to suffer a negative business impact because of an email-borne attack in 2018.<\/p>\n

Also, in line with the ESRA results, despite efforts, email-borne attacks are on the rise.<\/p>\n

The clear majority of Vanson Bourne respondents have seen untargeted phishing attacks (94 percent) or targeted spear-phishing attacks (92 percent) with malicious links in the past 12 months, with the volume of both attacks increasing 56 percent over the last year.<\/p>\n

Most respondents also reported seeing email-based impersonation attacks asking either to initiate wire transfers (87 percent) or for confidential data (85 percent) over the last year.<\/p>\n

Mimecast\u2019s solutions<\/h3>\n

\u201cMimecast\u2019s multilayered security inspection system is engineered to include more than 100 analytic techniques and threat data sources provided both by in-house development and third-party sources, including 3 separate AV engines, file sandboxing, static file analysis and other techniques,\u201d Gardiner added.<\/p>\n

\u201cNo single technique can be relied upon to stop the rapidly evolving attacks and organisations need to ensure they also have continuity during, and automated recovery after an attack to achieve cyber resilience for email.\u201d<\/p>\n
