Glasswall product offering
Product offeringCore offering
Glasswall fundamentally sells zero-trust Content Disarm and Reconstruction (CDR) cybersecurity software that rebuilds files and documents into safe, clean, known-good standards to eliminate malware, ransomware, and zero-day threats without relying on signatures, sandbox detonation, or internet lookups. Its platform comprises three core products — Embedded Engine (SDK), Halo (Kubernetes-based server), and Meteor (desktop application) — and is augmented by Foresight AI threat prediction, Find and Redact DLP, Storage Monitoring and Outlook Integration for Microsoft 365, ICAP Server for web proxies, and Halo Agent Skills for AI-assistant integration. The software is sold via subscription licensing and deployed on-premises, in the cloud, or in air-gapped environments.
Product overview
Glasswall offers a platform-plus-modules architecture centered on Content Disarm and Reconstruction (CDR) technology. The core platform consists of three main products: Glasswall Embedded Engine (SDK) for developer integration, Glasswall Halo (Server) for scalable enterprise deployment on Kubernetes, and Glasswall Meteor (Desktop) for automated local/cloud file cleaning. These are augmented by add-on modules including Glasswall Foresight (AI-powered threat prediction), Glasswall Find and Redact (DLP), Storage Monitoring and Outlook Integration for Microsoft 365 protection, ICAP Server for web proxy integration, and Halo Agent Skills for AI assistant integration. The platform is trusted by Five Eyes governments and NATO, and is mandated by NSA's Raise the Bar initiative for cross-domain solutions.

Glasswall competitors and assessment
Company assessmentDirect peers
- Votiro: Votiro is the most direct CDR competitor to Glasswall, offering file sanitization technology that rebuilds documents to known-good specifications. Both target government, defense, and enterprise customers with similar Zero Trust file security propositions.
- ReSec Technologies: ReSec Technologies provides CDR-based file security for enterprise and government customers, including air-gapped network deployments. Highly comparable to Glasswall Halo in deployment model and target use cases.
- Sasa Software: Sasa Software specializes in CDR and content security for cross-domain solutions, serving government and defense customers with similar file-rebuilding technology. Direct competitor in the regulated/defense CDR niche.
- OPSWAT: OPSWAT's MetaDefender platform provides file security including CDR-like sanitization, multiscanning, and DLP capabilities across enterprise and government markets. Overlaps with Glasswall's find-and-redact and CDR offerings.
- Menlo Security: Menlo Security acquired Deep Secure, a CDR-focused vendor, and offers file security as part of its browser isolation and Zero Trust platform. Comparable in targeting secure file transfer and cross-domain use cases.
- ReversingLabs: ReversingLabs provides advanced file analysis and threat intelligence that integrates with Glasswall Halo via partnership. Comparable in file security focus but approaches the problem via reputation/scanning rather than full reconstruction.
Broad incumbents
- Forcepoint: Forcepoint offers CDR-adjacent file security within its broader Data Loss Prevention and Cross Domain Solutions portfolio, competing for similar defense and government customers as Glasswall but with a wider security suite.
- Fortinet: Fortinet's security fabric includes file security and sandboxing (FortiSandbox) that overlaps with CDR's use cases. A broad incumbent that Glasswall ICAP integrates with but also competes against in enterprise file security.
- Trellix: Trellix (the merged FireEye/McAfee enterprise business) provides file analysis, sandboxing, and threat intelligence. Glasswall partners with Trellix but also competes for similar government and enterprise file security budgets.
Emerging players
- Perception Point: Perception Point provides advanced email and collaboration security with file scanning and threat detection capabilities, targeting enterprise M365 and Google Workspace environments — overlapping with Glasswall's M365 Outlook Integration and Storage Monitoring offerings.
