Email security
We’ve partnered with Mimecast to provide cloud-hosted email threat solutions.
Unlock 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).
How Mimecast works
We have substantial experience in implementing Mimecast email security solutions for Microsoft 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
- 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. Inspection
of URL's
- 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. Email content
checks
- 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.)
Email continuity service
In the event of a cyber attack, our Email Continuity service can allow no interruption in accessing your emails. All emails would fully recoverable due to the continuous sync and recover service.
Email will remain the main threat posed to organisational security going forward, either through attacks by hackers or user error.
