Brookfield manages over $1 trillion in assets across infrastructure, renewable power, private equity, and real estate - operating in 50+ countries with approximately 250,000 employees running physical assets and 4,400+ investment professionals. The threat surface is institutional-grade: critical infrastructure networks, power generation facilities, operational technology systems, cross-border data flows, and financial transaction platforms serving sovereign wealth funds, pension systems, and insurance companies. The attack model spans nation-state actors targeting energy grids, ransomware groups exploiting OT environments, and supply chain compromise across a globally distributed asset base.
Security operates at the intersection of financial services rigor and industrial control system reality. Teams protect both the investment management technology stack - deal flow platforms, portfolio analytics, client reporting systems - and the operational environments of owned assets, where downtime or compromise directly impacts power delivery, building operations, or transportation infrastructure. The founder-to-present continuity since 1899 means legacy systems coexist with modern cloud architectures, creating complex segmentation and monitoring challenges across jurisdictions with varying regulatory requirements.
The owner-operator model means security isn't just about protecting transactions - it's about ensuring continuous operation of physical assets that institutions depend on for stable, long-term returns. Cybersecurity teams work across asset classes with different maturity levels, from digitized real estate management systems to renewable power plants with embedded IoT and SCADA networks. The scale demands automation, but the criticality of assets requires human oversight and incident response capabilities that understand both IT and OT failure modes.
