  • Webinar: “Preventing Cyber Attacks on OT Networks and Industrial Control Systems”
    During the past few months, cyberattacks have increased against Operational Technology (OT) networks and Industrial Control Systems (ICS). Recent targets include a natural gas facility, water facilities, and steel manufacturers. Given the fact that critical infrastructure such as utilities, energy suppliers, and manufacturing facilities are exposed and at risk, it is essential to implement effective security in order to reduce the attack surface of these ICS and OT networks. Join Mati Epstein, Head of Industrial Control Systems at Check Point Software Technologies for insight on the realities surrounding today's vulnerabilities and how companies can protect their critical infrastructure without impacting operations going forward.
