Stop email impersonation before it damages your business
Sendmarc
DMARC Protection
Prevent unauthorised use of your domain, strengthen email security and improve trust in every message you send.
The Cost of
Unprotected Email
Cybercriminals regularly impersonate trusted organisations to:
Steal sensitive information
Deliver malware and ransomware
Commit invoice and payment fraud
Damage customer trust
Disrupt business operations
Many organisations assume they’re protected because they use Microsoft 365 or Google Workspace. However, without properly configured DMARC, SPF and DKIM policies, attackers may still be able to send emails that appear to come from your domain.
Many providers simply offer DMARC tools. We go further. Xeretec assesses, implements, manages and continuously optimises your email authentication strategy, helping you achieve full DMARC enforcement without disrupting legitimate business communications.
85% of cyber attacks affecting UK businesses originate from email.
Xeretec DMARC Enforcement
Enforcement is Risky
Without Clear Insight
Many organisations are unsure about DMARC because it’s invisible when working, difficult to troubleshoot when it isn’t, and risky to enforce without the right insight. That uncertainty leaves the door open for attackers to send spoofed emails from your domain, putting your reputation and customers at risk. In just 90 days, Xeretec can help you safely implement and enforce DMARC, preventing unauthorised use of your domain.

How Sendmarc
Works
Assess
We evaluate your current email security posture, reviewing existing SPF, DKIM, and DMARC configurations to identify gaps, risks, and opportunities for improvement.
Discover
Sendmarc analyses your email ecosystem and identifies all legitimate email sources associated with your domain.
Authenticate
We configure and validate SPF, DKIM, and DMARC records to ensure trusted email sources are properly authenticated.
Monitor
Detailed reporting provides visibility into email activity, authentication performance, and potential threats targeting your organisation.
Enforce
Once legitimate senders are verified, stricter DMARC policies can be applied to reject or quarantine fraudulent emails before they reach recipients.

FAQs
Find answers to common questions about Sendmarc and DMARC enforcement.
DMARC (Domain-based Message Authentication, Reporting and Conformance) is an email authentication standard that helps organisations prevent domain spoofing and phishing attacks.
Not necessarily. Microsoft 365 provides security features, but DMARC must still be configured and managed correctly for your domain.
When implemented properly, DMARC should not impact legitimate email delivery. Our phased deployment approach ensures authorised senders are identified before enforcement policies are applied.
Most organisations can begin monitoring within days, with full enforcement typically achieved after a period of analysis and optimisation of 90 days.
Yes. We can manage DMARC protection across multiple domains, brands, subsidiaries, and business units from a centralised platform.
