AWS re:Invent 2025 - Cyber Risk is Business Risk: Managing Cloud Security Without Disruption(SEC212)

Cyber Risk is Business Risk: Managing Cloud Security Without Disruption

The Evolving Cyber Risk Landscape

• Cyber attacks can have severe business impact, as seen with the £220 million loss and 5-week production shutdown for Jaguar Land Rover after a major breach.
• Cyber risk is now an operational risk that can disrupt core business functions and services, not just an IT issue.
• Boards and executives are now directly accountable for cyber security outcomes, with cyber risk impacting growth, customer trust, compliance, and operational resilience.
• The rapid adoption of cloud, AI, and remote work has dramatically expanded the attack surface, introducing new vulnerabilities and risks.

The Limitations of Traditional Security Approaches

• Organizations have historically relied on a patchwork of independent security tools, leading to:
  • High operational complexity and maintenance costs
  • Visibility gaps and inability to correlate threats across the environment
  • Reactive, firefighting security posture with poor alignment to business priorities
• Boards struggle to quantify cyber risk exposure and justify security investments, as traditional metrics do not map to business impact.

The Need for a Proactive, Risk-Based Approach

• To address these challenges, organizations must shift from reactive defense to a proactive, risk-based security strategy focused on:
  1. Reducing material business risk
  2. Lowering operational costs and complexity
  3. Increasing the speed and value of security initiatives
• Key elements of this approach include:
  • Continuous, comprehensive visibility across the hybrid, cloud-based attack surface
  • Mapping technical vulnerabilities and threats to business-critical assets and services
  • Quantifying cyber risk in financial terms to enable data-driven decision making

Cyber Risk Quantification and Prioritization

• Cyber risk quantification models, such as the FAIR (Factor Analysis of Information Risk) framework, enable organizations to:
  • Estimate the potential financial impact of specific cyber incidents (e.g., ransomware, data breaches)
  • Prioritize mitigation efforts based on the likelihood and magnitude of risks
  • Communicate cyber risk in business terms to non-technical stakeholders
• This data-driven approach helps justify security investments and align them with broader business objectives.

The Trend Micro Vision One Platform

• Northeast Georgia Health System (NGHS), a large regional healthcare provider, adopted the Trend Micro Vision One platform to address their security challenges:
  • Fragmented visibility across on-premises, cloud, and hybrid environments
  • Inefficient threat detection and response processes
  • Operational complexity and resource constraints
• By leveraging Vision One's integrated capabilities for risk exposure management, cloud security, and threat intelligence, NGHS achieved:
  • 60% reduction in time spent on false positive alerts
  • Improved team efficiency and centralized visibility
  • Simplified reporting to the board of directors, securing ongoing security investments

Key Takeaways

• Cyber risk is a critical business risk that must be managed proactively, not just reactively.
• A platform-based approach with comprehensive visibility, risk quantification, and business-aligned security strategies is essential to enable innovation and growth while mitigating cyber threats.
• Trend Micro Vision One, integrated with AWS cloud services, provides a practical solution to help organizations transform their security posture and become a true business enabler.
