Greystar is the world's largest rental housing company, managing over one million units and beds across nearly 250 global markets. Founded in 1993 and headquartered in the US, the firm operates across North America, Europe, South America, and Asia-Pacific, with a portfolio spanning multifamily housing, student housing, active adult communities, single-family rentals, modular housing, and logistics properties. The company employs more than 22,200 people worldwide and oversees real estate valued at over $300 billion in the US alone, with $79 billion in assets under management and $36 billion in development assets.
The security challenge at this scale is substantial: a distributed, global infrastructure connecting millions of residents, property management systems, financial transactions, and operational technology across residential and logistics properties. Threat models likely include tenant data protection, payment system integrity, access control across physical and digital perimeters, and securing operational technology embedded in building management systems. The attack surface spans corporate IT, resident-facing platforms, and the logistics side of the business.
Greystar's cybersecurity teams operate in the context of a highly regulated real estate and financial services environment, where resident PII, payment data, and investment records intersect. The company's geographic footprint across four continents means security operations must account for varying regulatory regimes and data sovereignty requirements. For security professionals, the draw is defending infrastructure at genuine scale - not a tech company's abstraction layer, but the systems that keep physical communities running.
