FileWall - 2026 Pricing, Features, Reviews & Alternatives

FileWall is a native security booster for Microsoft 365 that provides robust protection against file-based cyberattacks targeting business applications like Exchange Online, SharePoint, Teams, and OneDrive. Leveraging patented Deep File Analysis (DFA) technology with proprietary Content Disarm and Reconstruction (TrueCDR) algorithms, FileWall efficiently eliminates embedded malware in files that evade detection by traditional solutions.

By complementing Microsoft’s own defenses like Exchange Online Protection (EOP) and Microsoft Defender, formerly Advanced Threat Protection (ATP), FileWall delivers effective real-time protection against any unknown threat concealed in innocent-looking files from both external and internal sources. It offers one-click deployment for seamless activation across an organization’s Microsoft 365 ecosystem.

FileWall secures both internal and external users against ransomware, malware, and other cyberattacks using files as a threat vector. Its Deep File Analysis is uniquely capable of disarming threats hidden in nested files, archives, password-protected documents, and more.

Available as a cloud-based SaaS offering, FileWall integrates with Microsoft’s marketplaces and Cloud Solution Providers (CSPs) for easy procurement and licensing. As a Microsoft partner and member of the Microsoft Intelligent Security Association (MISA), FileWall meets enterprises’ need for robust yet easy-to-deploy defenses that close critical gaps in Microsoft 365’s native security.
