Seculetter DISARM is a cloud-based email security service designed to protect Microsoft 365 environments from phishing emails, ransomware, and business email compromise (BEC) attacks. The product integrates with Microsoft 365 through API connections without requiring MX record changes. The solution employs a multi-layered security approach combining threat intelligence, debugger analysis, and Content Disarm and Reconstruction (CDR) technology. The CDR functionality removes active content such as malicious URLs, JavaScript, and shellcode from email attachments, then reconstructs files to eliminate potential threats while maintaining document usability. DISARM analyzes both executable and non-executable files for malware detection, including compressed and encrypted documents. The debugger analysis component uses reverse engineering techniques to detect known and unknown security threats, including zero-day vulnerabilities and polymorphic malware that evade signature-based detection. The platform provides email profiling capabilities that alert recipients when emails arrive from senders with no recent communication history. It secures both external and internal email communications within organizations. Administrators can access a web-based management console for real-time email flow monitoring, policy configuration, and monthly reporting. Supported file types for CDR include Microsoft Office documents (doc/docx/docm/rtf, xls/xlsx, ppt/pptx/pptm), PDF files, image files, and various compressed formats (ZIP, 7Z, ARJ, RAR, TGA). The service offers VIP email information masking to protect sensitive data for critical users.
