Our vision is to enrich security for RPA robots by enabling immutability for activity logs. We guarantee the security of RPA logs by making them immutable, allowing log reconstruction when logs are altered by a third party and the real time backup of logs. We also provide secured access on logs using permission-based policies and advanced encryption. Using blockchain technology, Modex Blockchain Database provides the right alternative for data security and data protection against ransomware effects, as well as the right argument for data integrity against any possible litigation. As an UiPath Orchestrator plug and play logs module, Modex Blockchain Database is a custom, efficient and easy to adopt alternative for immutable and secure RPA activity tracking.
