Access your Cloudflare dashboard and navigate to the Email Security section. Here, you’ll find a list of pre-configured rules designed to protect against common threats. Review these rules; understand their purpose and impact.
To create a custom rule, select the “Create Rule” option. Choose a rule type (e. g., block sender, block attachment type, quarantine spam). Specify the criteria for your rule. For example, block emails from a specific domain or containing specific keywords in the subject line or body. Employ precise filtering parameters to minimize false positives.
Cloudflare allows you to prioritize rules, determining the order of evaluation. Prioritize rules based on your organization’s specific security needs. High-priority rules will be checked first. Carefully consider the order to prevent conflicts.
Regularly review and update your email security rules. Threat actors constantly change tactics. Review logs to identify bypassed rules, helping you refine existing ones or create new ones to address emerging threats. A proactive approach is key to strong email security.
Pro Tip: Use the rule logging feature to monitor the effectiveness of your rules. This provides insights into the types of threats blocked and allows you to adjust your security posture accordingly. Analyze this data regularly to maintain optimal protection.
Remember: Overly restrictive rules can impact legitimate email delivery. Strike a balance between robust security and usability. Test your rules thoroughly before deploying them widely.
For advanced customization, explore the API. The API allows for programmatic rule management, automation, and integration with other security tools. This offers greater control and scalability for larger organizations.
