GLIMPS Email Security for M365 is a SaaS email security solution designed for organizations using Microsoft 365. It connects to M365 environments via the Microsoft Graph API and operates asynchronously after email delivery, analyzing emails without impacting mail flow or user productivity. The solution performs multi-layered analysis across three dimensions: email headers and body, attachments, and URLs. Email analysis includes BEC and spoofing detection, SPF/DKIM/DMARC validation, over 500 specialized detection rules, and anti-spam filtering. Attachment analysis uses GLIMPS Deep Learning for zero-day threat detection, combined with multiple antivirus engines and recursive extraction. URL and link analysis draws on an enriched anti-phishing database, web categorization, and dangerous domain blocking. Analysis is performed by 30+ detection engines, including anti-phishing, anti-spam, YARA, heuristics, and anti-malware engines. Results are delivered in under 3 seconds, with automatic quarantine of detected threats requiring no user interaction. The platform is available in both SaaS and on-premise deployments, with identical features across both. Deployment is completed in approximately 15 minutes via Microsoft Graph API. All data is hosted in France, with no data transferred outside the EU, supporting GDPR compliance. An administration dashboard provides detailed analysis reports, quarantine management, real-time alerts, and exportable logs for SIEM integration. Each analyzed email generates a traceable report with history of detected threats and actions taken.
