5ironCyber

5ironCyber is a Franklin, Tennessee-based managed security services provider that runs 24/7 security operations exclusively for financial institutions — community banks, credit unions, and fintech companies that face heavy regulatory scrutiny but rarely have the budget to staff an in-house SOC around the clock. The company’s core offering pairs Managed Security Operations (SIEM monitoring, threat detection, and incident response) with MDR+ Endpoint Security, a managed detection and response layer aimed at catching threats that bypass perimeter controls.

Founded in 2017 by Jeremy Hopwood, 5ironCyber has grown to roughly $5 million in annual revenue without raising outside venture capital, funding its growth entirely through customer revenue. That trajectory has been recognized externally: the company has appeared on the Inc. 5000 list of fastest-growing private U.S. companies for four consecutive years, a ranking based on audited revenue growth rather than self-reported marketing claims.

The vertical focus on financial services is the company’s main differentiator from generalist MSSPs — its analysts work within the compliance context (FFIEC, GLBA-adjacent expectations) that community banks and credit unions operate under, rather than treating financial clients the same as any other vertical. What’s less publicly documented is independent, named-customer evidence of detection efficacy; most of what’s available is the company’s own marketing and directory listings rather than third-party validation.
