Liberty Mutual operates a global insurance infrastructure spanning 28 countries with roughly 45,000 employees processing personal and commercial insurance claims, policy underwriting, and risk assessments. As the 9th largest property and casualty insurer globally by gross written premium, the attack surface is substantial: customer PII across millions of policies, financial transaction systems, claims databases, and interconnected commercial insurance platforms serving multinational corporations. The threat model includes nation-state actors targeting financial data, ransomware groups exploiting legacy systems common in century-old institutions, and insider threats across a geographically distributed workforce. The security perimeter extends beyond typical enterprise boundaries into investment management operations through Liberty Mutual Investments, workers' compensation systems handling sensitive employment and medical data, and Solaria Labs - an innovation unit exploring insurtech integrations that introduce third-party API risks and emerging technology vectors. Commercial insurance for large enterprises means defending against supply chain compromises, while personal insurance lines create high-volume consumer data protection requirements under varying international privacy regimes across their 28-country footprint. Security teams face the operational reality of protecting both modern cloud infrastructure and decades-old mainframe systems still processing core insurance functions. The scale requires automation across identity management, threat detection, and incident response, while regulatory compliance spans insurance commission requirements, financial sector oversight, and data protection laws across multiple jurisdictions. Founded in 1912 as a workers' compensation provider, the organization carries technical debt alongside Fortune 100 resources - a combination that shapes both the security challenges and the tooling budgets available to address them.

In 2014, American Express Global Business Travel (Amex GBT) emerged from a strategic evolution that transformed how the world approaches corporate travel. When American Express divested their Global Business Travel division in a $900 million investment led by Certares LP, they created an independent entity that would redefine the industry. This was not just a business transaction - it was the recognition that modern companies needed a dedicated partner to navigate the complexities of global business travel, with technology and innovation at its core. Today, Amex GBT stands as the world's leading B2B travel platform, serving companies of all sizes across more than 140 countries. With 18,000 professionals and a suite of integrated solutions for travel, expenses, and meetings & events, the company has grown through strategic acquisitions including KDS, Hogg Robinson Group, Ovation, Egencia, and CWT. Going public in 2022 on the New York Stock Exchange marked a new chapter, but the mission remains unchanged: helping ideas travel by connecting people and businesses worldwide through innovative technology, expert service, and a commitment to making business travel a force for good.

American Transmission Co. operates the high-voltage backbone serving over 5 million consumers across Wisconsin, Minnesota, Illinois, and Michigan's Upper Peninsula. Formed in 2001 as the nation's first multi-state transmission-only utility, ATC owns and maintains critical grid infrastructure that connects generation to load - no retail customers, no power plants, just the wires that keep regional energy flowing continuously. The threat model here is straightforward: operational technology environments running RTUs and PLCs that can't afford downtime, plus enterprise systems managing grid planning and maintenance across a geographically distributed footprint. The security surface spans both IT and OT domains. On the OT side, remote terminal units and programmable logic controllers monitor and control transmission equipment in real time, requiring strict segmentation and monitoring to prevent unauthorized access or manipulation. Enterprise infrastructure includes cloud computing environments alongside traditional tools like Microsoft Office, MS Project, and Primavera for grid planning and operations coordination. The company emphasizes continuous operation - any disruption to these systems translates directly to power delivery risk across four states. ATC's technical challenges center on protecting legacy grid infrastructure while integrating diverse generation sources and newer technologies. This isn't a move-fast-and-break-things environment; it's a regulated utility where security decisions must balance availability requirements, safety protocols, and compliance mandates. The work involves securing industrial control systems, managing third-party vendor access to critical infrastructure, and maintaining visibility across geographically distributed substations and control centers.
