Email has been around for almost six decades and, during that time, has become one of the most important communication channels and powerful marketing tools available to businesses. Unfortunately, organisations are not the only ones benefiting from email’s popularity. Cybercriminals continue to exploit weaknesses in email security to launch phishing campaigns, impersonation attacks, ransomware incidents, and Business Email Compromise (BEC) scams at an ever-increasing rate. In fact, the majority of cyberattacks still begin with an email, making email security one of the most critical components of any cybersecurity strategy.

As technology evolves, security teams are finding it increasingly difficult to keep pace. The rapid adoption of generative AI has introduced a new wave of sophisticated cyber threats, enabling attackers to create convincing phishing emails, impersonation attempts, and social engineering campaigns at unprecedented scale. At the same time, organisations face growing attack surfaces due to hybrid working, cloud adoption, and an ongoing cybersecurity skills shortage. Many IT teams are stretched beyond capacity, leaving businesses exposed to threats that are becoming more frequent, more convincing, and more costly.

Against this backdrop, protecting your email domain has never been more important.

The Growing Risk of Email-Based Attacks

Last year saw record levels of phishing activity, with millions of attacks detected globally. Cybercriminals are increasingly using AI-powered tools to automate and personalise attacks, making it harder for employees, customers, and partners to distinguish legitimate communications from fraudulent ones.

One of the most damaging forms of attack is Business Email Compromise (BEC), where attackers impersonate trusted individuals or organisations to trick recipients into sharing sensitive information, transferring funds, or granting access to systems.

These attacks often rely on domain spoofing — the ability for cybercriminals to send emails that appear to come from your organisation.

Without the appropriate controls in place, your domain can become a weapon used against your employees, customers, suppliers, and brand reputation.

Why DMARC Matters

DMARC (Domain-based Message Authentication, Reporting and Conformance) helps organisations prevent unauthorised parties from sending email using their domain.

By working alongside SPF and DKIM authentication protocols, DMARC enables organisations to identify legitimate email sources, monitor email activity, and ultimately reject or quarantine fraudulent messages before they reach recipients.

The challenge is that implementing DMARC correctly is rarely straightforward.

Many organisations have multiple applications and services sending email on their behalf, often without complete visibility. Enforcing DMARC without understanding these dependencies can lead to legitimate emails being blocked, disrupting business operations.

As a result, many organisations delay implementation or remain stuck in monitoring mode, unable to realise the full security benefits DMARC can provide.


The Xeretec Difference: Assessment First

At Xeretec, we believe effective cybersecurity begins with understanding your environment.

Rather than rushing to enforcement, we start with a comprehensive assessment of your existing email security posture. This allows us to identify authentication gaps, uncover unknown email services, review current SPF, DKIM, and DMARC configurations, and establish a clear roadmap towards enforcement.

This assessment-led methodology is central to how we deliver IT and cybersecurity services. By understanding your business, users, applications, and operational requirements first, we can recommend solutions that strengthen security without introducing unnecessary risk or disruption.

We work collaboratively with your teams throughout the process, ensuring every legitimate email source is identified and validated before policy changes are introduced.


How Xeretec and Sendmarc Work Together

To deliver effective DMARC protection, Xeretec combines its consultancy and managed service expertise with the advanced monitoring and reporting capabilities of Sendmarc.

Together, we guide organisations through a structured process:

Assess
Evaluate your current email authentication posture, identify risks, and understand how email is being used across the organisation.

Discover
Sendmarc analyses your email ecosystem to identify all legitimate email sources associated with your domain.

Authenticate
Configure and validate SPF, DKIM, and DMARC records to ensure trusted email sources are properly authenticated.

Monitor
Gain visibility into authentication performance, email activity, and attempted abuse of your domain.

Enforce
Apply stricter DMARC policies to reject or quarantine fraudulent emails once legitimate senders have been verified.

Optimise
Maintain protection through continuous monitoring and management as your organisation adopts new applications, services, and technologies.


From Visibility to Protection

DMARC is not simply a technical configuration exercise. It is an ongoing process that requires visibility, expertise, monitoring, and continuous optimisation.

The combination of Xeretec’s assessment-led approach and Sendmarc’s intelligence platform provides organisations with the confidence to move from observation to enforcement safely.

Instead of wondering who is sending email on behalf of your business, you gain complete visibility. Instead of reacting to impersonation attacks, you actively prevent them. And instead of managing DMARC as a one-off project, you benefit from a continuously evolving security posture that adapts alongside your organisation.


Protect Your Brand Before Attackers Exploit It

Cybercriminals are becoming more sophisticated, AI is accelerating attack capabilities, and email remains the most common entry point into organisations.

The question is no longer whether your domain will be targeted, but whether you have the controls in place to stop attackers successfully impersonating your business.

With Xeretec and Sendmarc, organisations can move from uncertainty to protection in as little as 90 days.
