Consider these factors when defining your email resilience strategy

1. Protect Your Domain Identity

Implement SPF, DKIM, and DMARC to prevent spoofing and domain impersonation. Mailspike helps organizations assess, monitor, and improve their email authentication posture, reducing the risk of fraudulent use of corporate domains.

2. Use Real-Time Threat Intelligence

Modern attacks evolve quickly. Combined, global, and email-focused threat intelligence and reputation data makes organizations closer to identifying malicious IPs, domains, and emerging email threats before they reach users. 

3. Stop the mostly-local BEC and Email Fraud

Not all attacks contain malware. Many rely on executive impersonation, supplier fraud, or compromised accounts. And most attacks are local, making use of cultural, news, habits, and language profiles of each country and industry. This is the type of fraud that usually circumvents global security, especially for smaller countries. Choose Advanced anti-fraud, spoofing detection, and BEC monitoring with a strong local insight, to help identify suspicious activity before others, and before financial or reputational damage occurs.

4. Add a Dedicated Security Layer to Microsoft 365

Native cloud security is important, but organizations often require additional visibility, control, and compliance capabilities. A dedicated, security driven solution that integrates seamlessly with Microsoft 365, can provide the advanced filtering, message tracking, auditing, and security controls that the broadband, one-size-fits-all Exchange+Defender cannot.

5. Secure Inbound and Outbound Email

Email security shouldn't stop at the inbox. Outbound protection helps prevent account abuse, data leakage, and reputation damage while ensuring the reliable delivery of business-critical messages. At a time where Large providers block most suspicious behaviors, having the adequate relay solution can make a difference.

Final Thought

Effective email security is about layers. By combining email authentication, threat intelligence, anti-fraud protection, cloud email security, and outbound controls, organizations can significantly reduce their exposure to modern email-based threats.
