Calamu is a data-first security software company that provides a product called Data Harbor, designed to make stored data resilient against cyber attacks, including ransomware and data exfiltration. The company's core technology uses a patented process that transforms data into what it calls "Digital Sludge," rendering it unreadable and useless to unauthorized parties even in the event of a breach. Key capabilities of the Data Harbor platform include: - Real-time data transformation that eliminates common threat vectors - Automatic detection of suspicious anomalies within stored data - Sequestering of compromised data to contain breaches - Self-healing functionality that restores data automatically to maintain 100% operational continuity during and after attacks Calamu positions Data Harbor as a cyber vault for backup and recovery use cases, integrating with established data management and storage platforms. Named integrations include Veeam, Veritas, Dell, Nutanix, Wasabi, and StarWind, as well as an S3-compatible interface for broader compatibility. The platform is described as deployable within 30 minutes into existing environments. The company has been recognized in Gartner's Emerging Tech Report and the 2024 Gartner Hype Cycle Report under the "cyberstorage" category. Calamu targets organizations seeking to protect backup datasets from ransomware and data theft without replacing existing storage infrastructure.
