EMAIL SECURITY AND CONTINUITY

Mimecast Email Security

At Atlas Cloud, we’re one of few providers of industry-leading Mimecast email security and continuity solutions in the North East. We’ve partnered with the best in order to provide cloud hosted email threat solutions including phishing protection, ransomware prevention and spam filtering. Mimecast Targeted Threat Protection is seamlessly integrated with our UK customers’ email services.

Email is an integral part of how every business operates but it also represents a weak link for organisations due to the prevalance of ransomware attacks and human error. A recent survey found that 90% of businesses have seen an increase in the number of email phishing attacks over the past 12 months and 40% have seen the volume of impersonation attacks increase (source: mimecast.com).

We have substantial experience in implementing Mimecast email security solutions for Office 365 and Exchange. Every email that your company receives is put through three stages of threat assessment at a speed and detail that human precautions are unlikely to achieve. The three stages of our hosted email filtering service are:

1. Attachment inspection

Email attachment inspection

2. Inspection of URL's

Email URL inspection

3. Email Content checks

Email content checks
1. We look at any attachments within the email and carry out the following checks: 
  • Check for specific file types & macros
  • Run checks against malicious file database
  • Sandbox email attachments and open them in a safe environment to see if they execute as expected
2. Next we examine any URL’s within the email and perform the following checks:
  • Check any URLs in the message
  • Resolve them through to end destination
  • Check against malicious URL database
  • If the URL downloads a file this is executed in a safe sandbox environment
  • Content on the URL evaluated for spoofed content
3. Finally we inspect the content of the email for the following: 
  • Check against sender blocked/permitted lists
  • Check DNS authentication
  • Check sender reputation (Mimecast Greylisting)
  • Scan for spam (Mimecast Spam Filtering service)
  • Carry out content and impersonation checks (Mimecast Phishing Protection etc.)
