Data center cyber risk threatens credit quality across sectors, S&P Global says
Rising reliance on data centers is increasing the financial significance of cyber threats to digital infrastructure. The risk extends beyond operators to tenants and funding markets, including project finance and asset-backed securities tied to the sector.
Highlights
- S&P Global warns that a cyberattack on a major data center operator poses a significant and underappreciated threat to credit quality across sectors.
- Exposure from data center cyber risk extends to tenants, project finance markets, and asset-backed securities linked to digital infrastructure operations.
- Large investments by Amazon, Microsoft, Alphabet, and Oracle heighten the sector's strategic and credit relevance as data centers underpin financial, healthcare, and government operations.
Cyber threat to critical digital infrastructure
As reported by S&P Global Ratings, citing S&P Global, a report says that a cyberattack on a major data center operator and its facilities poses an increasing and underappreciated threat to digital systems and to the credit quality of a broad range of stakeholders.The report says the exposure reaches data center customers, including tenants that depend on uninterrupted digital capacity, as well as parties involved in financing those operations. It adds that the risk is relevant for the project finance market and for asset-backed securities linked to the sector.
S&P Global also states that the report does not constitute a rating action, framing the publication as a credit risk assessment rather than a change to any formal rating decision.
Broader implications for investors and industries
Digitalization has created growing dependence on data centers, which now underpin operations across financial services, technology, healthcare, telecommunications and government.The report highlights cloud services and the expanding importance of AI as factors that are turning data centers into foundational infrastructure. It also points to large investments by technology companies including Amazon, Microsoft, Alphabet and Oracle, underscoring the sector's strategic importance and the potential credit impact if cyber disruption hits a significant operator.
In our earlier article on the massive AI-driven data center buildout, we examined projections that AI infrastructure spending could take an unusually large share of U.S. GDP through 2032. We also noted that the shift from tech giants’ balance sheets to more complex, leveraged financing structures may widen systemic financial vulnerabilities, especially if revenue expectations fail to materialize.
