Why Visibility Gaps Fuel Lateral Movement Risk

#1714110: Why Visibility Gaps Fuel Lateral Movement Risk

Description:	More tools, more data and more spending haven't translated into fewer breaches - just bigger ones. Andrew Rubin, founder and CEO of Illumio, said the real problem isn't dwell time itself, but the industry's failure to detect and contain threats early. Modern breaches aren't caught in days or weeks; they often persist for months, wreaking financial and operational havoc. Security leaders, Rubin said, must rethink the perimeter model and address the attack surface inside the environment. Traditional defenses aim to keep threats out, but lateral movement allows attackers to escalate damage once inside. Observability, especially at the network level, plays a critical role in detecting threats before they spread. "If they can't move laterally, the amount of damage they can inflict is solely contained to that one resource," Rubin said. Organizations should adopt tooling that surfaces anomalies quickly and empowers defenders to act fast before small issues become catastrophic events. In this video interview with Information Security Media Group at Microsoft Ignite 2025, Rubin also discussed: Why more telemetry doesn't equal actionable visibility; How artificial intelligence can automate mundane tasks to free security teams; Why operational agility matters more than perfect plans. Rubin has more than 25 years of experience in cybersecurity and technology, focusing on zero trust, segmentation, network security, and regulatory and compliance management. As CEO of Illumio, he leads strategy and serves as an executive sponsor for major clients including Citi, HSBC, Salesforce and Microsoft.
