Email Security Meets DMARC: A Dual Defence Against Modern Threats

In today’s cybersecurity landscape, email remains both the most essential business tool and the most dangerous. Every day, cybercriminals exploit trust to impersonate brands, trick employees, and steal data. To truly secure business communications, organisations need more than spam filters. They need the combined strength of AI-powered email security and DMARC enforcement.

Why Email is Still the #1 Cyberattack Vector

Despite advancements in security, phishing remains the most successful attack method. Why? Because it targets people, not just systems. Attackers use lookalike domains, impersonated senders, and psychological tactics to trick recipients into clicking or responding.

Business Email Compromise (BEC) alone cost global businesses over $2.7 billion last year. And while traditional filters catch obvious threats, today’s phishing emails are often personalized, socially engineered, and free of links or attachments—making them nearly invisible to outdated tools.

The Role of AI in Email Threat Detection

This is where IRONSCALES’ AI-Powered Email Security Solution makes a difference. The system uses behavioural analysis and real-time threat intelligence to:

• Detect advanced phishing attempts—even from trusted or compromised sources

• Prevent BEC and impersonation of key executives or vendors

• Continuously adapt to new attack techniques using machine learning

• Automatically remediate threats with minimal user impact

• Integrate seamlessly with Microsoft 365 and Google Workspace

Unlike legacy tools, IRONSCALES’ email security learns from how your team communicates—identifying deviations, unusual tone shifts, and changes in sender behavior to flag threats faster and more accurately.

DMARC: Protecting Your Domain from Being Weaponized

While AI secures your inbound email, DMARC (Domain-based Message Authentication, Reporting & Conformance) protects your outbound reputation. DMARC ensures only authorized sources can send emails using your domain, stopping attackers from spoofing your brand in phishing campaigns.

Without DMARC, attackers can send convincing emails that appear to come from your CEO, HR team, or IT helpdesk—, causing real damage before they're even detected.

By implementing and properly managing DMARC, organisations can:

• Block unauthorised senders from using their domain

• Gain visibility into how their domain is being used

• Improve email deliverability and sender reputation

• Comply with security frameworks like NIST and ISO 27001

Why DMARC Alone Isn’t Enough

DMARC is a powerful tool, —but it’s only one layer. It doesn’t protect against phishing from lookalike domains, compromised third-party vendors, or internal account takeovers. That’s why pairing DMARC with IRONSCALES’ AI-driven email threat detection is essential. Together, they create a multi-layered Defense that not only stops spoofing but also detects impersonation attacks and internal threats in real time.

Working Together: A Unified Strategy

The synergy between AI email security and DMARC management delivers complete protection:

• DMARC blocks impersonation at the domain level

• AI detects threats that bypass authentication

• Reporting tools give full visibility into attack sources

• Automated responses reduce dwell time and damage

This layered defence ensures that your people, brand, and data are safe—, from both external actors and compromised internal accounts.

Final Thoughts

Email threats are evolving—and so must your defences. By combining IRONSCALES’ AI-Powered Email Security with automated DMARC management, you gain layered protection that stops attackers before they can reach your inbox or impersonate your domain. It’s time to move beyond reactive security.
