My company provides engineering services to organizations that provide critical infrastructure. Critical Infrastructure provides essential services such as water, electric and transportation that underpins American society and serve as the backbone of our nation's economy, security, and health. We deal largely with water and waste water and have in recent years extended our services to include Operational IT services. We work extensively with programmable logic controllers (PLCs) which in turn control valves, switches and measuring devices among other things and the software that monitors and reports on these devices.
When we get a new customer, it is not uncommon to find out that there is little to no documentation or knowledge of the existing infrastructure. A tool such as NTM would be perfect IF there weren't reports of PLCs being damaged or even bricked by netscans and similar. The problem most always stems from older hardware that has not been updated, but with hundreds if not thousands of items that make up the Internet of Things we support, running any utility that has the potential to do damage is not going to happen.
I'm curious if anyone else has had this experience, or what you do to prevent this from occurring. NTM has the potential to save us hundreds of hours a year, but only if it doesn't cost us millions in damage!
