Bill Brinkley

Bill Brinkley is the Chief Information Security Officer of the State of Wisconsin.

Career path

By November 13, 2025, he held the title Chief Information Security Officer. That is the title shown on the presentation he gave that day at the 2025 Wisconsin Statewide Procurement Conference.

An event page for the 2026 Wisconsin Governor's Cybersecurity Summit gives a longer form of his title: State Chief Information Security Officer & Director, Wisconsin Department of Administration. This places his security role within the state's Department of Administration.

Organizational setting

The Division of Enterprise Technology's senior leadership page lists Brinkley as State Chief Information Security Officer and Director of the Security Bureau.

That team is responsible for strategic IT planning and for delivering Wisconsin's IT services and solutions.

Contracts, code and supply chains

Brinkley's procurement conference presentation was titled Building Trust Through Contracts, Code, and Supply Chains.

Its agenda covered managing risk across the contract lifecycle, software and service transparency, updating the Cybersecurity Business Review (CBR) process and building resilient supply chains.

The transparency section opened with the question of what role a Software Bill of Materials (SBOM) plays. It then turned to how the state increases supply chain visibility.

The same section asked how the State Standards, which are based on NIST 800-53 and SSDF, drive software assurance to improve vendor accountability.

The final part of the presentation began by explaining what the CBR process is.

Statement for the 2026 summit

For the 2026 Wisconsin Governor's Cybersecurity Summit, Brinkley wrote that he looked forward to joining fellow SLTT leaders in Appleton.

His statement tied protection of the state to infrastructure design. He wrote that a shared commitment to protecting Wisconsin can deliver secure by design infrastructure that adapts to new challenges.

He also connected security work to the state workforce: "By prioritizing automation and retiring legacy risks, we empower our workforce with greater speed and security."

He described the gathering as a vital step in the effort to build a resilient Wisconsin that serves everyone.

The same event page carries a statement from Governor Tony Evers. Evers called the summit a key part of the state's work to keep Wisconsin's cyber infrastructure resilient and secure.
