Under Attack?

Trust your email with DMARC enforcement

Impersonation attacks continue to be a major cyber threat. One third of organisations in 2020 saw impersonation as their biggest email threat. Combating this threat needs increasing resources from secure email gateways, threat intelligence feeds to user awareness training. These tools can and do help our users from being trapped by these threats.

Machine learning, content analysis and other email inspection technologies are hit and miss; they are particularly vulnerable to newer or rarer attacks such as highly-targeted and well-crafted attacks.

Using DMARC, DKIM and SPF technologies we can protect our users, customers and partners from email attacks impersonating our domains. While important for all organisations, this is particularly important for B2C organisations where customer trust is a vital commodity.

Key benefits of DMARC enforcement:


  • Publishing a DMARC record protects your brand by preventing unauthenticated parties from sending mail from your domain.
  • Enhancing your domain reputation increases delivery rates to recipients.


  • DMARC reports increase visibility into your email program by letting you know who is sending emailsfrom your domain.
  • Without this visibility, it is challenging to understand who and what is using your domain.


  • DMARC provides a strong instruction to mail servers to quarantine or discard email that doesn’t authenticate.
  • Trust and defend the email that comes from your domains.
