Glasswall Halo
Glasswall Halo is a scalable Zero Trust file protection solution, deployable on-prem, in the cloud or in air-gapped networks. Accessible via Web UI, APIs and ICAP Servers.
Built on powerful cloud-native
architecture
Glasswall Halo is a Kubernetes-based solution, which makes our CDR cloud-native, highly scalable and easily deployable for a wide range of security environments.
Seamless integration with API endpoints and ICAP servers
Our API endpoints ensure our trust file protection capabilities can be delivered and managed at critical stages within document workflows, anywhere files are moved or stored. Glasswall Halo can also be used for real-time threat removal from web traffic, by seamlessly integrating with web appliances, such as firewalls, proxies and Gateways, through ICAP server requests.
Multiscanning and advanced threat intelligence
ReversingLabs adds additional layers of multiscanning security and real-time threat intelligence to Halo with instant hash lookups and file handling based on malware status. Safe files are automatically approved, while suspicious ones are blocked.
Zero Trust CDR anywhere files are moved or stored
Key features
ICAP integration for web proxy servers, enabling SSL sanitization in real-time
Bring Zero Trust data protection to your M365 environments with Glasswall Storage Monitoring for SharePoint or OneDrive
85+ supported file types and counting
Manage high-risk content in files (such as macros) with tailored security policies

Glasswall Halo is a file security platform that uses Content Disarm and Reconstruction (CDR) technology to remove embedded threats from files. It sanitises documents by rebuilding them to a known-good standard, eliminating malware without relying on detection-based methods.
Glasswall Halo analyses files at a structural level and reconstructs them according to strict file format standards. Instead of scanning for known malware signatures, it removes any content that does not conform to the file specification, preventing zero-day and unknown threats.
Traditional antivirus tools detect known threats using signatures or behavioural analysis. Glasswall Halo does not rely on detection. It removes potentially malicious elements from files by rebuilding them safely, making it effective against unknown and zero-day attacks.
Yes. Because Glasswall Halo does not depend on malware signatures or prior knowledge of threats, it protects against zero-day exploits and previously unseen file-based attacks.
Yes. Glasswall Halo can be integrated into email gateways, web gateways, secure file transfer systems, and other security workflows via APIs and deployment options. It is designed to work alongside existing security tools.
Yes. Glasswall Halo is used in highly regulated sectors such as government, defence, financial services, and critical infrastructure, where file-based threats pose significant operational risk.
Glasswall Halo preserves the intended visual and functional integrity of files while removing embedded threats. Any active content that violates file format standards or presents risk may be removed to ensure safety.
Glasswall Halo can be deployed on-premises, in private cloud environments, or within hybrid architectures, depending on organisational requirements and security policies.
