All OT equipment you use and the lines on which they operate are modernized in the Industry 4.0 digital transformation process. Cyber ​​Security must be discussed at all stages in this transformation process. It has been observed that IT Security PenTest methods are not used, and if they tried in OT infrastructures, they result in adverse damages. SCADAfence functions like a camera in your facility and interprets and synthesizes a copy of your traffic. It creates alarms to make you proactive. Besides, it operates as a hidden camera and attackers who attampt to infiltrate the facility from inside or outside leave traces on the network layer while communicating with C&C by creating very minor densities of network traffic (information gathering, scanning, etc.) to mature the attack. SCADAfence captures therese minor but risky traffics, compares them with attack types and signature patterns and interprets them to inform you before the attack becomes active.
