How Digital Twin Testing Protects the Grid Without Risk
What if you could simulate a cyberattack on your power grid without touching the real system? What is Digital Twin Testing? A digital twin is a virtual replica of a physical system. In cybersecurity, it allows testing attacks and behaviors in a safe, isolated environment. Why It’s Important Traditional testing risks: Digital twin testing eliminates…
