GLIMPS Fortress is an on-premise file repository platform that collects, stores, and continuously analyzes files using AI-based detection and multiple antivirus engines. It is designed for organizations that handle large volumes of files, including open source components, third-party libraries, and business binaries. The platform supports over 25 analysis engines and can process more than one million files per day via a Kubernetes-based architecture. Files are analyzed using GLIMPS AI, built-in YARA rules, and multiple antivirus engines to detect malware, malicious scripts, and zero-day threats. A core capability is retrohunting: when new detection rules, YARA signatures, or updated AI models are added, they are automatically applied to all previously stored files. If a new threat is identified retroactively, users are automatically alerted. Files can be ingested from a variety of sources, including S3 buckets, internal repositories, MalwareBazaar, GitHub, Docker Hub, and OS package repositories. Two storage modes are available: full file duplication in the Fortress repository, or metadata-only storage with files remaining in the original S3 location. Each file maintains a living record of metadata, verdicts, and detection history. The platform supports observable extraction and exports indicators of compromise (IOCs) such as hashes and signatures to threat intelligence platforms. Reanalysis frequency is configurable, ranging from every few hours to weekly intervals. The solution is deployed entirely on-premise, keeping all data within the customer's infrastructure. It is intended for use by SOC teams, CSIRT teams, software development managers, and big data managers.
