These barriers can postpone deal closure and slow initial uptake in the smart cities market.

Cyber-Security and Data-Privacy Concerns

High-profile breaches elevate cyber security from an IT matter to a political flashpoint. The 2024 ransomware attack on Dallas prompted the United States Cybersecurity and Infrastructure Security Agency to demand air-gapped backups for all federally funded smart-city projects, raising total system costs. Under GDPR, European cities must anonymize facial data within 90 days, pushing compute to the edge and reducing algorithm accuracy by up to 12% relative to cloud processing. Baltimore canceled its aerial-surveillance pilot in 2025 because of privacy concerns, underlining how regulatory uncertainty can strand investments. As a result, procurement teams often favor vendors that bundle zero-trust architectures and third-party penetration testing, adding expense and lengthening sales cycles.
