EY Cybersecurity was founded in 1989, giving them over three decades of experience in cybersecurity services. In an industry where many agencies are less than 5 years old, 37+ years of sustained operations signals stability, client retention, and the ability to adapt through multiple technology cycles. Today, the team is enterprise.
EY Cybersecurity has a presence across 7 states: New York, Illinois, California, Texas, Virginia, Georgia, Massachusetts. A multi-state presence can be important for enterprise buyers who need local account management, on-site workshops, or time-zone-aligned teams. It also suggests the agency has scaled beyond a single-office operation.
Penetration testing engagements cost $10K–$60K depending on scope. Security assessments and compliance readiness range from $20K–$100K. Managed security retainers (continuous monitoring, incident response) run $5K–$30K/month. These are industry benchmarks for cybersecurity services agencies at the level AgencyCluster curates.
