Attackers are weaponizing public and legitimate AI assistant APIs and defenders must adjust.

Why cyber resilience - not just compliance - is critical for manufacturing OT environments

Your manufacturing environment might be compliant, but that doesn't mean it's protected against a cyberattack. Even compliant systems can fall victim to cybercrime.
