DMARC Domain Protection: Prevent Spoofing & Phishing Attacks | Solid Systems

DMARC Domain Protection

Secure Your Business Email & Prevent Spoofing

What is Domain Protection?

Email is one of the most targeted attack vectors for cybercriminals using sophisticated AI attacks. Business domains are frequently exploited in phishing campaigns, allowing attackers to impersonate companies and deceive customers, employees, and partners.

With Secure365 Domain Protection, businesses can lock down their domains, preventing unauthorised use and email-based threats such as spoofing, phishing, and business email compromise (BEC).

  • DMARC, DKIM, and SPF enforcement to secure outgoing emails
  • Protection against email impersonation and domain spoofing
  • Improved email deliverability by verifying legitimate senders

Without strong domain security measures, businesses risk:

  • Cybercriminals impersonating their company to send fraudulent emails
  • Phishing scams using fake email addresses to steal sensitive information
  • Email security vulnerabilities leading to data breaches

How Domain Protection Works

Secure365 integrates domain security protocols into Microsoft 365, ensuring that only authorised senders can use your domain for email communication
