IT vs OT Security – Understanding the Differences
IT and OT systems have traditionally kept separate to prevent cyber attacks from moving between the two networks. Industry 4.0 has created the imperative to converge the two realms. In this article we discuss the differences between IT and OT, focusing on the security challenges posed by convergence.
In the aftermath of the Colonial and JBS SA ransomware attacks: how to protect yourself while optimizing your ROI on Risk Reduction
We discuss the methods of optimizing your OT security through breach & attack simulation and risk assessment, to prioritize the most effective countermeasure mitigations.
SCADA Security: What It Is, and Why It Matters
In this overview of cybersecurity for SCADA systems, we cover: In this article we will cover what Is SCADA Cyber Security, the problems related, why SCADA security issues matter and how to perform a Security Risk Assessment for SCADA systems.
Transitioning to an OT Security Operations Center (SOC) – 3 Key Considerations
CIOs and business executives are beginning to see the advantages of integrating OT processes into their established security operations center (SOC), creating a new security approach known as an OT SOC.
Colonial Pipeline Paid Hackers Nearly $5 Million in Ransom
Based on the amount paid as ransom to cyber-attackers, the magnitude of loss perceived by Colonial Pipeline obviously exceeds the $5M paid if we add up all the expenses involved in reaching Colonial’s recovery point objectives (RPO).

The Goldrush for Operational Cyber Security (OT)
IoT security spending is expected to increase by 300% to $6 billion by 2023. Radiflow CEO Ilan Barda reveals what’s behind this trend and why people remain the most vital tool in the fight back.
What’s Included in an OT Security Assessment?
The convergence of OT and IT has given hackers a much broader “attack surface.” OT security assessments provide a clear picture of the risks facing their networks, accounting for probability of a cyberattack on all business units and the impact of the attack.
OT Cyber Security: What Are the Common Challenges?
Traditional industrial control systems (ICSs) are self-contained; communications take place over physical wires between and among system components, and the system’s operation is independent of any other systems or networks in the plant.
