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

DMARC (Domain-based Message Authentication, Reporting & Conformance)

Enforces a reject policy to block spoofed emails from using your domain.

Provides reporting on authentication failures to support proactive email security.

DKIM (DomainKeys Identified Mail)

Adds cryptographic signatures to outbound emails to verify message integrity.

Confirms that sent messages are authentic and have not been altered during delivery.

SPF (Sender Policy Framework)

Specifies authorised mail servers that can send emails on behalf of your domain.
Blocks spoofed messages sent from unauthorised servers to reduce impersonation risk.

Phishing & Spoofing Prevention

Prevents AI-driven spoofing attacks that mimic your domain or trick recipients.
Authenticates all email traffic to ensure legitimacy and security.
