Public Storage

Public Storage operates at a scale that's easy to underestimate until you look at the numbers: over 170 million net rentable square feet across thousands of locations in the U.S. and Europe, all of it online and app-accessible for reservation and management. That's an S&P 500 real estate company founded in 1972, now running a physical attack surface the size of a small city - every keypad, every access log, every tenant credential forming a distributed footprint that doesn't get to have downtime. The threat model here isn't theoretical. A self-storage empire this large deals with high-frequency access control at thousands of unmanned or lightly staffed sites, customer payment data at scale, and operational technology tied to physical security systems - all while maintaining the online interfaces customers use to book and manage units. The cybersecurity team operates across that full stack, from cloud infrastructure and application security to the convergence of IT and OT at the facility level. With more than 5,000 team members, the organization has the depth to build dedicated security functions rather than stretching generalists across domains. The company's commitments to sustainability - LED retrofits, solar installations across facilities - add another layer of connected infrastructure worth defending. For security engineers who think in terms of distributed systems with physical endpoints, the scope here is concrete and the attack surface is real.
