Cloudflare Email Security’s gateway scans incoming emails for malware using multiple techniques. Configure your DNS records to route email traffic through Cloudflare. This directs all emails through Cloudflare’s security infrastructure before they reach your mail servers.
Utilize Cloudflare’s advanced anti-malware features; these actively identify and block emails containing malicious attachments or links. Regularly review the Email Security dashboard for threat reports; this provides insights into detected threats and helps you fine-tune your security settings.
Implement email authentication protocols like SPF, DKIM, and DMARC. These strengthen your email’s authenticity, making it harder for malicious actors to spoof your domain and send phishing emails. Adjust your threat score thresholds; Cloudflare lets you specify the sensitivity level for blocking suspicious emails. A higher threshold catches more, but might increase false positives.
Leverage the quarantine feature to examine emails flagged as suspicious before they reach your inbox. This helps you review flagged emails and fine-tune the system over time. Consider enabling Cloudflare’s advanced features such as sandboxing for attachments; this analyzes potentially harmful attachments in a safe environment before they interact with your systems.
Monitor your email security logs diligently for any unusual activity or anomalies. Proactive monitoring helps detect and address security threats early. Regularly update your Cloudflare Email Security settings and keep your software current; this ensures that you benefit from the latest protection.
