Digital Immunity (DI) delivers groundbreaking Cybersecurity protection for Operational Technology environments. DI prevents the execution of malware attacks, both file-less and file based by constantly verifying the integrity of executing code, operating systems and related applications in memory at runtime. DI leverages a bioinformatics approach to prevent the execution of malware attacks including zero days without any prior knowledge of exploits or vulnerabilities. While protecting against bad processes with a lightweight sensor that resides on the endpoint, good processes are protected to run so that operations will continue without disruption. Digital Immunity is being deployed in the protection of Operational Technology and mission-critical environments globally.
