It's said that 36 states have now started using Albert sensors, which can detect hacking attempts and even send alerts to state and federal government agencies.
According to Bloomberg, the sensors are based on a system which used to guard federal government networks, and while they can't block cyberattacks, they can send supsicious inforation to an information sharing centre near Albany, New York.
From there, it's said the agents can then attempt to figure out if it's a genuine hacking attempt, and then notify the states affected.
Jeanette Manfra - a top official at the Department of Homeland Security - previously told CNET that hackers will generally find a way through.
She said: "Pretty much anything is going to have some vulnerability that somebody is going to try to exploit."
