We are proud to be named a Leader across four categories in ISG’s evaluation of the U.S. cybersecurity services market. The recognition reflects EY’s ability to connect strategy, engineering, managed operations and quantum readiness to help enterprises build resilient, compliant security programs.

ISG highlights EY’s risk-led strategic advisory, engineering-first technical delivery, AI-enabled SOC/MDR operations and structured approach to post-quantum readiness. Across these services, EY combines regulatory insight, multi-vendor execution, automation and phased transformation planning.

According to Yash Jethani of ISG, EY stands out for its “advisory-first, risk-led approach,” “engineering-first delivery model” and “AI-enabled next-gen SOC/MDR security operations.” He also highlights EY’s regulatory-aligned approach to building crypto-agile, future-ready security architectures.

As the U.S. market shifts toward accountable, AI-aware and resilience-driven cybersecurity, EY’s four Leader recognitions demonstrate capabilities spanning strategy, implementation, operations and long-term cryptographic transformation.
