Ep149: Rabbi Joey Felsen | Founder of Jewish Study Networks

By Michael Matias, CEO of Clarity and Forbes 30 Under 30 alumCybersecurity is at a turning point, driven by artificial intelligence (AI). My conversation with Jonathan Roizin, CEO of Flow Security—now part of CrowdStrike—reinforced the urgent need for organizations to rethink data protection strategies in an era of dynamic, fluid information exchange.The Shifting Nature of Data SecurityRoizin, a veteran of elite Israeli cybersecurity organizations, has spent over 15 years tackling cyber threats. His focus on "data in motion" highlights a critical reality: data no longer sits in static environments. It moves continuously across cloud services, SaaS platforms, and APIs, fundamentally altering security needs.The stakes are enormous. IBM’s 2023 Cost of a Data Breach report revealed that the average breach now costs $4.45 million. Meanwhile, organizations use over 130 SaaS applications, a number increasing nearly 18% annually. Yet, many still rely on outdated security models that assume clear perimeters around data.The Decline of Traditional DefensesRoizin emphasized the need to move beyond legacy Data Leakage Prevention (DLP) strategies, which were designed for endpoint security and internal networks. “The boundaries have been broken,” he explained. As organizations migrate to cloud environments like AWS, Google Cloud, and Microsoft Azure, perimeter-based security models are becoming ineffective. Gartner predicts that by 2025, 85% of businesses will operate primarily in the cloud.AI as a Threat and a Defense MechanismThe rise of AI compounds security challenges. AI-powered tools—such as coding assistants and automated meeting note-takers—introduce new vulnerabilities. Employees often share sensitive information through unmonitored AI platforms, inadvertently exposing critical data. A Team8 report found AI-driven phishing attacks have surged by more than 2,000%, with nearly half using GPT-generated communications.Yet, AI also strengthens cybersecurity. Flow Security leverages AI-driven automation to classify and monitor sensitive data in real time, providing dynamic protection that traditional security models cannot achieve.The Urgent Need for Proactive AI IntegrationThe future of cybersecurity demands a philosophical shift—security cannot rely on passive visibility. Instead, AI-driven real-time interventions must become the norm. Roizin and I share a conviction: cybersecurity teams should not simply identify risks but actively prevent breaches before they occur.My work at Clarity reinforces this belief. AI-driven techniques can protect organizations far more effectively than reactive security models. Intelligent automation minimizes false positives, allowing security teams to focus on genuine threats rather than being overwhelmed by noise.Looking AheadThis conversation reaffirmed my thesis: cybersecurity must evolve alongside rapidly shifting technological landscapes. Static security frameworks no longer suffice. Organizations must integrate AI-driven defense mechanisms that adapt to the continuous movement of data—or risk falling behind.Those who embrace this paradigm will unlock unprecedented security resilience. Those who delay may find themselves vulnerable to increasingly sophisticated cyber threats.

Artificial intelligence (AI) is reshaping cybersecurity—not just for digital threats but also for critical physical infrastructure like railways. My conversation with Miki Shifman, Co-Founder and CTO of Cylus, underscored the urgent need to extend cybersecurity beyond traditional digital domains to protect transportation systems.Railway Cybersecurity: A Growing ConcernShifman, a cybersecurity expert and Israeli intelligence veteran, co-founded Cylus in 2017 to address vulnerabilities in railway systems. Historically, rail safety focused on mechanical redundancy and human oversight. But modern trains—autonomous, high-speed, and digitally connected—face unprecedented cyber risks. As Shifman put it, “The boundaries have been broken.”Recent incidents highlight the severity. London’s railway shutdown last September exposed the economic and societal disruptions cyberattacks can cause. A similar event in New York’s subway system would ripple far beyond transportation, affecting healthcare and public safety.Emerging Threats and AI’s RoleRailway cyber threats fall into two categories: availability threats that halt train operations and safety threats that could lead to collisions or derailments. Many railway systems lack adequate encryption and authentication, making vulnerabilities deeply embedded. AI accelerates these risks—lowering the expertise needed to execute sophisticated attacks. Tools like ChatGPT enable less-experienced hackers to gain insights into specialized rail protocols, expanding the pool of potential attackers.Regulatory Response and AI-Powered DefenseWith railways classified as critical infrastructure, regulatory bodies in the EU and U.S. are mandating stronger cybersecurity measures by 2025. However, these solutions must integrate carefully to avoid interfering with operational safety.AI also strengthens defenses. Cylus uses AI to enhance threat detection, real-time monitoring, and anomaly detection while reducing false positives. AI boosts productivity across railway cybersecurity, from rapid prototyping to regulatory compliance automation. “AI helps turn compliance from a burden into an asset,” Shifman noted.The Future of Railway CybersecurityRail cybersecurity lags behind other critical infrastructure sectors, but AI provides an opportunity to leap forward. Organizations embracing AI-driven security will gain unprecedented protection—while those slow to adapt remain vulnerable to increasingly sophisticated threats.When asked about AI’s future in rail security, Shifman admitted, “We’re still evolving our understanding. But ignoring AI simply isn’t an option. This technology changes the landscape weekly.” That mindset—alert, adaptable, and proactive—is exactly what the railway industry needs today.

Artificial intelligence (AI) is no longer a mere enhancement in cybersecurity—it’s essential. My conversation with Dr. Dorit Dor, Chief Technology Officer at Check Point Software Technologies, reinforced AI’s transformative role in defending against cyber threats. As a pioneer in Israel’s cybersecurity sector, Dorit has been shaping security strategies for nearly three decades.AI’s Expanding Role in CybersecurityFrom Check Point’s early days to its global prominence, Dorit has emphasized the need to shift from reactive threat detection to proactive prevention. “AI empowers attackers to scale their operations dramatically,” she explained. Today, targeted cyberattacks occur at mass scale, making real-time defense a necessity.The Challenge of AI-Driven ThreatsOrganizations now face AI-generated threats daily, including deepfakes and hyper-targeted phishing campaigns. Dorit stressed the urgency of stopping attacks as they happen, not just detecting them afterward. The conversation highlighted a growing vulnerability: supply chain security. Cybercriminals increasingly exploit weak links within supply chains, underscoring the importance of securing every aspect of an organization’s ecosystem. “Supply chain attacks have significantly increased,” she warned, calling for rigorous internal security among providers.AI and the Future of Cybersecurity OperationsBeyond threat prevention, AI is reshaping cybersecurity roles. “The human factor will increasingly shift from direct intervention to supervising AI agents executing defensive tasks,” Dorit noted. Traditional manual security processes are giving way to AI-driven systems, requiring cybersecurity teams to act as strategic managers rather than hands-on defenders.The Urgency to AdaptCybersecurity must evolve at the pace of emerging threats. AI-driven attackers pose a growing risk, and organizations failing to integrate AI into their security frameworks will struggle to keep up. Dorit’s perspective aligns with my own experiences at Clarity, where AI-driven cybersecurity is not a luxury—it’s a necessity. As she put it, “Organizations today need solutions that can respond automatically and intelligently. We must empower our defenses to act decisively when under attack.”Looking AheadAI stands at a crossroads: both a threat multiplier and a defensive enabler. Organizations must act swiftly to integrate AI into their cybersecurity strategies, ensuring they stay ahead of increasingly sophisticated threats. Dorit’s insights serve as both a warning and a roadmap—those that embrace AI will not just survive but thrive in the evolving digital landscape.
