Case Study: U.S. State Government Agency achieves 90% reduction in phishing and doubles staff productivity with Tenable Networks (Tenable.sc Continuous View)

State Government Agency Turns to Tenable to Protect Valuable Taxpayer Data and Deliver on Compliance Requirements

A U.S. state government revenue agency responsible for safeguarding the personally identifiable information of millions of taxpayers — including motor vehicle records — faced rising phishing attacks, manual and time‑consuming vulnerability monitoring, an increasingly distributed workforce, and stringent compliance requirements (IRS 1075 / NIST 800‑53). The agency needed continuous, real‑time visibility of its expanding attack surface and a turnkey compliance solution to reduce cyber risk and meet audit demands.

They implemented Tenable.sc Continuous View to gain real‑time asset visibility, agent‑based scanning, intuitive dashboards, and predefined NIST/IRS compliance checks. As a result, phishing attempts fell by about 90% (from 10–15/day to roughly 1 or zero), staff productivity roughly doubled with IT workload cut in half, downtime decreased, audits became easier with turnkey reports, and the agency achieved faster patch prioritization and stronger compliance readiness.
