Information Services Group, or ISG, has warned that agencies at the federal, state and local levels face increasingly sophisticated cyberthreats. To strengthen security, the government is adopting advanced technologies, such as artificial intelligence, to mitigate cyberattacks, the research and advisory firm revealed in its new report.
The 2025 ISG Provider Lens Cybersecurity — Services and Solutions report assessed the cybersecurity trends that impact the U.S. public sector. It is part of ISG’s Provider Lens Quadrant research series, which extracts insights from empirical and data-driven research and market analysis combined with real-world observations.

What ISG Found
According to the report, the convergence of information and operational technologies in supply chains and critical infrastructures creates major cyber risks. ISG said supply chains involved in government procurements require regular vendor risk management and monitoring. The firm also noted that an early notification system prevented a ransomware attack against transportation infrastructure.
AI offers enhanced cybersecurity through threat detection, automated discovery of vulnerabilities and predictive analysis.
More agencies are also addressing cyberthreats by deploying cloud security posture management and workload protection platforms, which can safeguard critical applications across distributed systems.
“Public agencies need strong data protection strategies to continue delivering services and maintain public trust,” said Nathan Frey, ISG partner and U.S. public sector lead.
Top Government Technology Providers
The report also assessed 86 cybersecurity solutions and service providers across six quadrants: identity and access management, extended detection and response, technical security services, security service edge, strategic security services, and next-generation security operations center and managed detection and response.
IBM is the leading provider across five quadrants. Meanwhile, Accenture, Deloitte, Capgemini, Infosys, HCLTech and EY led in three quadrants.
“Providers enable clients to align security measures with agency goals and build effective defenses with limited resources,” commented Gowtham Sampath, assistant director and principal analyst for ISG Provider Lens Research.
