Unsafe emails bypass incumbent security systems; report
Mimecast's ESRA report highlights how organisations continue to receive dangerous files via email
Mimecast has discovered that nearly a quarter of "unsafe" emails are being delivered to users' inboxes.
Mimecast's Email Security Risk Assessment (ESRA) report noted a continued challenge of securing organisations from malicious attachments, dangerous files types, impersonation attacks, as well as spam.
To date, Mimecast's ESRA reports have inspected more than 45 million emails that had passed through email security systems, however it found that 31% were deemed unsafe. From this, Mimecast uncovered 10.8 million pieces of spam, 8.682 dangerous file types, 1,778 known and 503 unknown malware attachments and 9,677 impersonation emails to date.
The report urges organisations to enhance their cyber resilience strategies for email by adding a multi-layered approach, such as a third-party security service provider.
The report also found that some the top email cloud platers were missing commonly found advanced security threats, which means organisations are vulnerable by missing millions of spam emails and thousands of threats and allowing them to be delivered to the users' email inboxes.
Ed Jennings, chief operating officer at Mimecast, said: "They (organisations) should ensure there's a plan in place that covers advanced security, data management and business continuity, as well as awareness training to the end user, which combined help prevent attacks and mitigate business impact.
"These quarterly Mimecast ESRA reports highlight the need for the entire industry to work toward a higher standard of email security."
