Ensure comprehensive attachment filtering is applied

Why This Matters

Without comprehensive attachment filtering, malicious files can bypass your email security and reach your users. Malware, ransomware, and phishing attachments remain a primary vector for attacks. Configuring strong filtering reduces the risk of successful compromise through email-borne threats.
