Main Business, Products and Services

Guardtime Cybersecurity is a business unit focused on productizing our technology stack for cybersecurity applications. Our flagship product MIDA is a completely new approach to security where every digital asset (firewall rules, configs, virtual machine images) are wrapped in a cryptographic container which provides the integrity and provenance information for that asset. Any change in that asset that is outside of policy can be detected and mitigated in real time in direct contrast to the traditional approach of  log analysis and anomaly detection.
