Lexington, MA – March 5, 2019 – Mimecast Limited (NASDAQ: MIME), a leading email and data security company, today announced the latest Email Security Risk Assessment (ESRA) report, an aggregated analysis of tests that measure the efficacy of widely used email security systems. This quarter’s report found that email delivered with malicious URLs, a recently added part of the testing, has increased by more than 125 percent in comparison to last quarter’s results.
The data was analyzed and, as in past periods, Mimecast was found to deliver superior efficacy. New to the ESRA report, was testing for malicious URLs. Mimecast detected 463,546 malicious URLs contained in the 28,407,664 emails delivered were deemed “safe” by an organization’s existing email security system, averaging to one malicious URL in every 61 emails. Recent research Mimecast conducted with Vanson Bourne independently also confirms that malicious URLs are a rampant problem, with 45 percent of the 1,025 respondents saying the volume of these URL-based attacks or those with dangerous attachments
In addition to malicious URLs, the latest ESRA report also found 24,908,891 spam emails, 26,713 malware attachments, 53,753 impersonation attacks, and 23,872 dangerous file types of the 232,010,981 total emails inspected were all missed by these incumbent security solution providers and delivered to inboxes, putting individuals and organizations at risk.

Impersonation fraud also continues to grow and present challenges. The new research from Mimecast and Vanson Bourne revealed that 41 percent of respondents reported seeing an increase in impersonation fraud from vendors or business partners asking for money, sensitive information or credentials – with 38 percent saying they’ve seen an increase of impersonation fraud from well-known internet brands.
