CPS Energy is the largest community-owned electric and gas utility in the U.S., serving over 907,000 electric and 373,000 natural gas customers across San Antonio and seven adjoining counties. Founded in 1860, it operates as a public utility that has generated $8 billion in revenue for the City of San Antonio. It's also the number one solar generator in Texas.
For a cybersecurity professional, the threat model here is critical infrastructure. The attack surface spans industrial control systems (ICS) and operational technology (OT) networks managing the grid and gas distribution, alongside conventional IT and customer-facing digital platforms. The team defends systems where the consequences of a breach are measured not in data loss, but in physical disruption to a major metropolitan area's power and gas supply.
The organization employs around 3,500 people. Security operations would involve monitoring and defending a hybrid OT/IT environment, a domain where network segmentation, protocol analysis, and threat hunting aren't theoretical exercises. The scale - nearly a million customer endpoints and the generation assets feeding them - means the work is consequential and concrete.
