Case Study: City National Bank of Florida strengthens security maturity with Deepwatch MDR

City National Bank of Florida Elevates Security Maturity with the Deepwatch Guardian MDR Platform™

City National Bank of Florida (CNB), a large community bank based in Miami, needed to strengthen its cybersecurity program as threats grew more sophisticated. With limited visibility, slow log management tools, and a small security team supporting more than 1,000 employees, the bank needed to improve detection, response, and audit readiness without adding headcount. CNB engaged Deepwatch for its Guardian MDR Platform™ and Managed Firewall services.

Deepwatch implemented a fully managed SOC with 24/7/365 detection, response, and firewall management, integrated with CNB’s existing Splunk environment. The partnership helped CNB move from reactive to resilient, cut audit response time from days to minutes, reduce estimated cyber insurance premiums by nearly 80%, and improve incident dwell time and overall security maturity. Deepwatch also became a trusted extension of the CNB team, supporting incident response, compliance, and ongoing security strategy.
