Enables cost-effective asset and threat management while requiring improvements in support and training
The time it takes to train itself is a concern. Initially, it will not identify many assets, as it needs time to read the information before finding the assets. Some detections can go wrong, and it may not understand certain industrial protocols. While installation and deployment are easy, upgrading from one version to another can be challenging.
