Customer Challenge
The Internal Revenue Service (IRS) manages vast amounts of sensitive taxpayer data across over 600 interconnected systems, including monolithic Tier 1 mainframe applications and Tier 2 server-based systems. Protecting this critical data from evolving cybersecurity threats posed significant challenges, worsened by complex integration dependencies and limited legacy documentation. The IRS also needed to comply with federal mandates for data encryption—in-transit and at-rest—across diverse database technologies like SQL Server, DB2, Oracle, and VSAM. A robust cybersecurity strategy was required to address emerging legislative requirements such as Zero Trust Architecture and Quantum Resistant encryption, while ensuring business continuity in serving millions of taxpayers annually.
